I write firmware for microcontrollers for a living. Not the really tiny ones, but the ones with maybe a megabyte of memory. Basically I'm the $50,000 consultant those companies can't afford. The part of the industry I'm seeing is incredibly weird.

I'm under NDA so I can't name any companies I've worked with, but you've absolutely heard of some of them; it's not unlikely you've used their products yourself.

When it comes to devices with embedded microcontrollers, they tend to have absolutely no clue what they're doing. That's why they're calling us in, after all. They will absolutely use hobbyist hardware for prototyping, with no plans for transitioning to anything production grade. Or maybe they will build custom hardware before even considering use cases for their device. They will develop new and exciting (read: buggy) transfer protocols because they're unaware of existing standard interfaces.

And it's... fine?

It's completely true that to bring an electronics device to market, you need to be good at a lot of different things, across very different domains. You can't be equally good at all of them

And yes, it's weird that the software, the part that defines what the product does is the one most likely to be treated as an afterthought, outsourced to specialists instead of building relevant expertise in-house*.

But unlike, say, paint chipping off the casing, or devices catching fire, or bad marketing resulting in no sales, etc., inefficient software is mostly invisible.

The end-consumer doesn't notice that they're flashing those SOCs individually, they don't see the terrible custom bluetooth stack, and they'll never know how many internal processes rely on copying files to USB drives by hand.

They also usually don't see the kernel version on that 5,000€ device (connected to the internet!) being 20 years out of date. Which, uh, that one might have visible consequences one day.

*to be fair, writing good firmware is also just hard. Competent systems programmers are rare, and getting rarer over time.

At my last job, we sold lots of hobbyist electronics stuff, including microcontrollers.

This turned out to be a little more complicated than selling, like, light bulbs. Oh how I yearned for the simplicity of a product you could plug in and have work.

Background: A microcontroller is the smallest useful computer. An ATtiny10 has a kilobyte of program memory. If you buy a thousand at a time, they cost 44 cents each.

As you'd imagine, the smallest computer has not great specs. The RAM is 32 bytes. Not gigabytes, not megabytes, not kilobytes. Individual bytes. Microcontrollers have the absolute minimum amount of hardware needed to accomplish their task, and nothing more.

This includes programming the thing. Any given MCU is programmed once, at the start of its life, and then spends the next 30 years blinking an LED on a refrigerator. Since they aren’t meant to be reflashed in the field, and modern PCs no longer expose the fast, bit-bangable ports hobbyists once used, MCUs usually need a third-party programming tool.

But you could just use that tool to install a bootloader, which then listens for a magic number on the serial bus. Then you can reprogram the chip as many times as you want without the expensive programming hardware.

There is an immediate bifurcation here. Only hobbyists will use the bootloader version. With 1024 bytes of program memory, there is, even more than usual, nothing to spare.

Consumer electronics development is a funny gig. It, more than many other businesses, requires you to be good at everything. A startup making the next Furby requires a rare omniexpertise. Your company has to write software, design hardware, create a production plan, craft a marketing scheme, and still do the boring logistics tasks of putting products in boxes and mailing them out. If you want to turn a profit, you do this the absolute minimum number of people. Ideally, one.

Proving out a brand new product requires cutting corners. You make the prototype using off the shelf hobbyist electronics. You make the next ten units with the same stuff, because there's no point in rewriting the entire codebase just for low rate initial production. You use the legacy code for the next thousand units because you're desperately busy putting out a hundred fires and hiring dozens of people to handle the tsunami of new customers. For the next ten thousand customers...

Rather by accident, my former employer found itself fulfilling the needs of the missing middle. We were an official distributor of PICAXE chips for North America. Our target market was schools, but as a sideline, we sold individual PICAXE chips, which were literally PIC chips flashed with a bootloader and a BASIC interpreter at a 200% markup. As a gag, we offered volume discounts on the chips up to a thousand units. Shortly after, we found ourselves filling multi-thousand unit orders.

We had blundered into a market niche too stupid for anyone else to fill. Our customers were tiny companies who sold prototypes hacked together from dev boards. And every time I cashed a ten thousand dollar check from these guys, I was consumed with guilt. We were selling to willing buyers at the current fair market price, but they shouldn't have been buying these products at all! Since they were using bootloaders, they had to hand program each chip individually, all while PIC would sell you programmed chips at the volume we were selling them for just ten cents extra per unit! We shouldn't have been involved at all!

But they were stuck. Translating a program from the soft and cuddly memory-managed education-oriented languages to the hardcore embedded byte counting low level languages was a rather esoteric skill. If everyone in-house is just barely keeping their heads above water responding to customer emails, and there's no budget to spend $50,000 on a consultant to rewrite your program, what do you do? Well, you keep buying hobbyist chips, that's what you do.

And I talked to these guys. All the time! They were real, functional, profitable businesses, who were giving thousands of dollars to us for no real reason. And the worst thing. The worst thing was... they didn't really care? Once every few months they would talk to their chip guy, who would make vague noises about "bootloaders" and "programming services", while they were busy solving actual problems. (How to more accurately detect deer using a trail camera with 44 cents of onboard compute) What I considered the scandal of the century was barely even perceived by my customers.

In the end my employer was killed by the pandemic, and my customers seamlessly switched to buying overpriced chips straight from the source. The end! No moral.

Top 5 Challenges of Embedded Software Development 2025

Businesses are concentrating on efficient methods to evaluate the data and produce insights that will help them improve their business processes and make wise decisions as a result of the rapid generation and gathering of data by enterprises worldwide. This need is being met by artificial intelligence (AI) and machine learning (ML), which also automate processes, solve complicated problems, and allow experience-based self-learning.

Almost every industry, including banking, consumer electronics, aerospace, automotive, security, and others, has experience with embedded systems. The accuracy, dependability, speed, and low power consumption of embedded systems are well known, and they can be applied to a greater range of tasks. A variety of microprocessors, programming languages, and operating systems are needed for the perfect embedded system, which is made up of both hardware and software.

For consumer goods like phones, robots, modems, automobiles, toys, security systems, appliances, televisions, digital watches, etc., many manufacturers utilize embedded software. Embedded software makes a device's hardware function in accordance with our specifications. Firmware, another name for embedded software, is housed in the hardware to form a single embedded system. It supports the operation of mission-critical devices like industrial automation systems, electronic control units, and anti-lock brakes in automobiles, among others. However, development organizations must also overcome certain obstacles presented by embedded software.

Let's talk about a few of the difficulties in developing embedded software.

Stability – Any unexpected behavior on the part of an embedded system can cause chaos and pose significant risks. Its behavior should be consistent under all conditions, and stability is crucial.

Safety – Given that embedded systems are utilized in numerous vital and life-saving functions in all kinds of critical environments, safety is one of their most important challenges. It is distinguished by constraints and stringent demands on testing, quality, and engineering know-how.

Connectivity – Given that there are numerous ways to connect to the internet—Ethernet, Wi-Fi, LoRa, cellular, Bluetooth, and other sources—this is one of the major challenges faced by embedded software developers. Every source has advantages and disadvantages of its own, and developers need to be aware of the various software stacks in order to ensure that the hardware functions.

Security – Developers face a difficult task in protecting their devices against ever-more complex security threats. Due to the devices' interconnectedness, the hazards associated with IoT devices are increasing rapidly as they become more and more popular worldwide. Hacking attacks are a common occurrence, and it's important to identify precisely which information needs to be protected.

Over-the-air-Updates – Once the device is online, developers will be able to remotely update the firmware. Customers can update software on their own with the aid of IoT. But in any deployment involving thousands of devices, the developers must concentrate on

Generate a firmware update

Save it to all the devices

Verify that they are delivered from a reliable source.

Run that specific update on the devices at the appropriate time.

Always be prepared to roll back updates right away in the event of a problem.

the ESP32 is such a fantastic chip it's a miracle anyone working on general purpose embedded hardware uses anything else. Integrated network stack on the chip plus WiFi and Bluetooth. Two cores. Most boards come with 4+MiB of flash. 2 ADC's and a DAC. 160-240MHz core clock.

I guess there's all those mini Linux ARM boards but the additional cost is significant enough that it really puts it in a different class.

Houston Texas Appliance Parts: Ambiq Launches AI SDK for Ultra-Low Power MCUs

Ambiq Launches AI SDK for Ultra-Low Power MCUs

by Houston Texas Appliance Parts on Friday 17 February 2023 06:21 PM UTC-05

Ambiq Micro is the latest microcontroller maker to build its own AI-focused software development kit (SDK). The combination of Ambiq's Neural Spot AI SDK with its ultra-low power sub-threshold and near-threshold technologies will enable efficient inference: Ambiq's figures have keyword spotting at less than a milliJoule (mJ). This efficiency will suit IoT devices, especially wearables, which are already a big market for the company.

Artificial intelligence applications on Cortex-M devices require specialized software stacks over and above what's available with open-source frameworks, such as TensorFlow Lite for Microcontrollers, since there are so many challenges involved in fine-tuning performance, Carlos Morales, Ambiq Micro's VP of AI, told EE Times.

"[Arm's CMSIS-NN] has optimized kernels that use [Arm's cores] really well, but getting the data in and moving it to the next layer means there are a lot of transformations that happen, and [Arm] has to be general about that," he said. "If you carefully design your datapath, you don't have to do those transformations, you can just rip out the middle of those things and just call them one by one–and that gets very efficient."

Neural Spot's libraries are based on an optimized version of CMSIS-NN, with added features for fast Fourier transforms (FFTs), among others. Morales points out that, unlike cloud AI, embedded AI is focused in large part on about a dozen classes of models, so it's an easier subset to optimize for.

"A voice-activity detector running in TensorFlow would be terrible, you'd just be spending all your time loading tensors back and forth. But you write it [at a lower level], and suddenly you're doing it in two or three milliseconds, which is great," he said.

Further headaches include mismatches between Python and the C/C++ code that runs on embedded devices.

"We created a set of tools that let you treat your embedded device as if it were part of Python," Morales said. "We use remote procedure calls from inside your Python model to execute it on the eval board."

Remote procedure calls enable easy comparison of, for example, Python's feature extractor or Mel spectrogram calculator to what's running on the eval board (a Mel spectrogram is a representation of audio data used in audio processing).

Neural Spot includes an open-source model zoo with health (ECG classifier) and speech detection/processing examples. Speech processing includes models for voice activity detection, keyword detection and speech to intent. Ambiq is working on AI models for speech enhancement (background noise cancellation) and computer vision models, including person detection and object classification.

The Neural Spot AI SDK is built on Ambiq Suite—Ambiq's libraries for controlling power and memory configurations, communicating with sensors and managing SoC peripherals. Neural Spot simplifies these configuration options using presets for AI developers who may not be familiar with sub-threshold hardware.

The new SDK is designed for all fourth-generation Apollo chips, but the Apollo4 Plus SoC is particularly well suited for always-on AI applications, Morales said. It features an Arm Cortex-M4 core with 2 MB embedded MRAM, and 2.75 MB SRAM. There's also a graphics accelerator, two MIPI lanes, and some family members have Bluetooth Low Energy radios.

Current consumption for the Apollo4 Plus is as low as 4 μA/MHz when executing from MRAM, and there are advanced deep sleep modes. With such low power consumption, he said, "suddenly you can do a lot more things," when running AI in resource-constrained environment.

"There are a lot of compromises you have to make, for example, reducing precision, or making shallower models because of latency or power requirements…all that stuff you're stripping out because you want to stay in the power budget, you can put back in," Morales added.

He also pointed out that while AI acceleration is important to saving power, other parts of the data pipeline are just as important, including sensing data, analog-to-digital conversion and moving data around memory: Collecting audio data, for example, might take several seconds while inference is complete in tens of milliseconds. Data collection might thus account for the majority of the power usage.

Ambiq compared internal power measurements for the Apollo4 Plus running benchmarks from MLPerf Tiny, with published results for other microcontrollers. Ambiq's figures for the Apollo4 Plus have the energy consumption (µJ/inference) at roughly 8 to 13× lower, compared with another Cortex-M4 device. The keyword-spotting inference benchmark used less than a milliJoule, and person detection used less than 2 mJ.

Sub-threshold operation

Ambiq achieves such low power operation using sub-threshold and near-threshold operation. While big power savings are possible using sub-threshold voltages, it is not straightforward, Scott Hanson, founder and CTO of Ambiq Micro, told EE Times in an earlier interview.

"At its surface, sub-threshold and near-threshold operation are quite simple: You're just dialing down the voltage. Seemingly, anybody could do that, but it turns out that it's, in fact, quite difficult," he said. "When you turn down voltage into the near-threshold or sub-threshold range, you end up with huge sensitivities to temperature, to process, to voltage, and so it becomes very difficult to deploy conventional design techniques."

Ambiq's secret sauce is in how the company mitigates for these variables.

"When faced with temperature and process variations, it's critical to center a supply voltage at a value that can compensate for those temperature and process fluctuations, so we have a unique way of regulating voltage across process and temperature that that allows subthreshold and near-threshold operations to be reliable and robust," Hanson said.

Ambiq's technology platform, Spot, uses "50 or 100" design techniques to deal with this, with techniques spanning analog, digital and memory design. Most of these techniques are at the circuit level; many classic building block circuits, including examples like the bandgap reference circuit, don't work when running in subthreshold mode and require re-engineering by Ambiq. Other challenges include how to distribute the clock and how to assign voltage domains.

Running at lower voltage does come with a tradeoff: Designs have to run slower. That's why, Hanson said, Ambiq started by applying its sub-threshold ideas in the embedded space. Twenty-four or 48 MHz was initially sufficient for ultra-low power wearables, where Ambiq holds about half the market share today. However, customers quickly increased their clock speed requirements. Ambiq achieved this by introducing more dynamic voltage and frequency scaling (DVFS) operating points—customers run 99% of the time in sub-threshold or near-threshold mode, but when they need a boost in compute, they can increase the voltage to run at higher frequency.

"Over time, you'll see more DVFS operating points from Ambiq because we want to support really low voltages, medium voltages and high voltages," Hanson said.

Other items on the technology roadmap for Ambiq include more advanced process nodes, architectural enhancements that increase performance without raising voltage and dedicated MAC accelerators (for both AI inference and filter acceleration).

Highly Integrated Wireless Microcontroller from ST Simplify Design of BLE/ZigBee/Thread Applications

STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, is simplifying the design of competitively priced and power-efficient wireless equipment for applications like smart buildings, smart industry, and smart infrastructure by introducing new development tools and software for STM32WB wireless microcontrollers.

ST’s highly integrated STM32WB contains a 2.4GHz radio and Arm® Cortex®-M4 and Cortex-M0+ MCU on the same chip, which eliminates numerous RF-circuit design challenges that can add time and uncertainty to a project. Just a small number of external components are needed, such as an antenna chosen for the application, to complete the hardware design. The MCU includes numerous peripherals, including a 12-bit analog-digital converter (ADC), digital interfaces, and a crystal-less USB 2.0 Full Speed interface in selected models. Protocols supported are Bluetooth® LE 5.2, Zigbee®, OpenThread, and proprietary protocols, including combinations of such protocols with concurrent modes.

As a member of the STM32 family, the market-leading Arm Cortex-M MCUs, the STM32WB benefits from the extensive and market-proven STM32Cube ecosystem that provides a rich selection of development tools and software.

“The STM32Cube ecosystem is already widely used and is also broadly supported by third-party developer resources that help accelerate project completion,” said Hakim Jaafar, STM32 Wireless Marketing Director, STMicroelectronics. “Our latest wireless enhancements extend the STM32 family’s capabilities to handle new demands and use cases, further enhancing the most complete and robust solution on the market.”

Strengthening support for wireless design, the STM32WB ecosystem provides all the necessary embedded software bricks and tools to get users started easily with their applications. The STM32CubeWB MCU package is loaded with many examples and brings a full set of peripheral drivers (HAL and LL), all the necessary radio stacks including Bluetooth 5.2, Zigbee 3.0, OpenThread v1.1, and 802.15.4 MAC for proprietary protocols, as well as example implementations of several concurrency models (static and/or dynamic) for these stacks. Software tools like STM32CubeMX and STM32CubeIDE offer direct support of the radio stacks in their GUI for easy access and configuration. Users can easily select and configure profiles and clusters for popular standards and benefit from ready-to-use examples.

In addition, extra controls for the power estimation tool contained in the STM32CubeMX configurator help calculate the RF-subsystem contribution to the overall power consumption budget. Users can set up various scenarios for an accurate assessment of battery runtime.

Houston Texas Appliance Parts: Wireless SoCs Solve Connectivity Challenges

Houston Texas Appliance Parts

Wireless SoCs Solve Connectivity Challenges

by Houston Texas Appliance Parts on Monday 30 January 2023 02:21 PM UTC-05

Wireless systems-on-chip (SoCs) are favored by IoT system designers for their high functionality, low power consumption and space savings. These devices are comprised of a number of key components, including the processors, radios, power management, memory, interfaces and peripherals.

One of the biggest drivers in wireless SoCs is the growing need for multi-protocol support to meet the requirements of different IoT devices. Chipmakers need to keep up with existing standards that continue to evolve as well as new wireless standards. These include Wi-Fi, Bluetooth LE, Bluetooth classic, 802.15.4, ZigBee, Thread, Z-Wave, Matter, cellular and other proprietary wireless protocols.

Through this integration and multi-protocol support, wireless SoCs are solving some of the biggest technical challenges around wireless design while simplifying development by providing all of the necessary functionality, along with the connectivity and security in one device. But designers aren't on their own; SoC makers also provide complete ecosystems and reference designs that can lower design risk and shorten the design cycle.

"A wireless SoC typically comprises the radio itself—one or more, depending on the application—a MAC/PHY for the Wi-Fi and PHY for Bluetooth, along with a power management unit, memory, various I/O ports, a debug port, possibly an analog-to-digital converter and bus management IP," said Brandon Bae, senior director of product marketing for wireless connectivity at Synaptics Incorporated. "Interfaces for external power amplifier and low-noise amplifier options, with associated switches, are also good to have."

Brandon Bae (Source: Synaptics Incorporated)

Depending on the protocols supported and the end applications, the components in a wireless SoC could be different, said Dhiraj Sogani, senior director of wireless product marketing at Silicon Labs. "Power optimization, longer range, robust connectivity, higher processing power, more peripherals and higher memory will continue to be the driving trends in wireless SoCs, and we will see continuous improvement in these."

Wireless SoCs are also packed with security features, making them suited for a range of embedded IoT systems, such as smart homes, smart metering, building automation and fitness devices.

"Security is increasingly a concern to protect personal data and to protect IP, and many SoCs are adding features to address security at multiple hardware and software levels," said Nathalie Vallespin, wireless product line marketing manager at STMicroelectronics.

Highly integrated wireless SoCs

As demand grows for wireless SoCs, chipmakers continue to meet requirements for better security and greater interoperability and are adding advanced features for sensors, graphics, artificial intelligence and machine learning. There is also a drive toward multi-protocol connectivity support with options for Wi-Fi, Bluetooth, LoRa, Zigbee, Matter and other protocols.

"There is always a requirement for a higher level of integration in the wireless SoCs to meet the application use cases, simplify IoT device development and reduce cost," Sogani said.

One of the key areas is a higher level of hardware and software integration, which includes the integrated applications processor, integrated networking stacks, cloud connectivity, digital and analog peripherals, additional GPIOs and higher memory, along with support for new protocols like Matter, Amazon Sidewalk and Wi-SUN, he added.

"Integration of multiple protocols is becoming critical," Sogani said. These include the combinations of Wi-Fi and BLE and 802.15.4 and BLE, as well as Wi-Fi, BLE, 802.15.4 and even sub-gigahertz integration.

"Bluetooth classic integration is also needed to support legacy headsets," he added. "These protocols need to operate concurrently, which needs significant hardware and software work."

Dhiraj Sogani (Source: Silicon Labs)

In addition, "Matter over Thread and Matter over Wi-Fi is gaining significant momentum, as it enables interoperability of different ecosystems, such as Google, Amazon and Samsung," Sogani said. "Wi-SUN is becoming more critical for smart-city deployments. Amazon Sidewalk shows significant promise to become a leading protocol for neighborhood connectivity."

Vallespin noted that the evolution in standards is also enabling new use cases: "In Bluetooth Low Energy, audio is creating many new use cases to manage new user experiences and is replacing the Bluetooth classic technology. Matter technology, just announced late last year, is a new standard for connected-home applications, and ultra-wideband is increasingly being used for car access control."

STMicroelectronics offers a wireless roadmap based on its popular STM32 family of microcontrollers and ecosystem. These include the STM32WB series for Bluetooth LE, Thread, Matter and Zigbee and the STM32WL for LoRa and other sub-gigahertz protocols. "STM32 wireless products add best-in-class IPs to smoothly migrate to wireless platforms," Vallespin said.

Sogani noted two other key trends, including the integration of machine learning for IoT edge devices for simple audio, vision and data applications like keyword spotting, motion detection and glass-break detection, as well as security integration at the hardware and software level for improving IoT device security.

Synaptics' Bae agreed that there is a higher degree of integration coming: "We're looking at advancing to finer nodes to not only shrink the die size, but it also frees up space to integrate more memory for more features for a given package size. The drivers tend to be functionality, size, power and cost, so if we can provide greater functionality for a given footprint while also improving power consumption, our customers like that.

"It's not always good to move to a smaller package, even when that's possible, as that requires board redesigns," Bae said. "More functionality is often preferred."

Similarly, Vallespin said the process node is a key factor in delivering new degrees of integration. "Smaller geometries allow greater integration."

Latest advances

Wireless SoC vendors agreed that new product development is driven by wireless standards and the need for higher functionality, more integration and lower power consumption.

For example, Silicon Labs' wireless SoC roadmap focuses on "intelligent wireless connectivity for IoT devices." The company offers a wide range of wireless solutions, including Wi-Fi, Bluetooth, 802.15.4, ZigBee, Thread, Z-Wave and proprietary wireless.

Silicon Labs' latest advances include its 2.4-GHz wireless MG24 SoC for Bluetooth and multiple-protocol operations. The MG24 supports Matter over Thread as a single-chip solution—with a range of up to 200 meters indoors for OpenThread—while also enabling Bluetooth commissioning of new devices on the same chip, Sogani said. "The MG24, combined with the ultra-low–power Silicon Labs RS9116 or Silicon Labs WF200 Wi-Fi products, enables development of Matter over Wi-Fi 4."

Silicon Labs also offers the FG25, the company's new flagship SoC for Wi-SUN, which is one of the world's first open protocols for smart-city and smart-utility applications. "The EFF01 is the FG25's corresponding amplifier that boosts signal range by 2× when used together," Sogani said.

He said the FG25 "will be the world's most secure smart-city solution, with long range, the largest memory capacity of any SoC in the Silicon Labs portfolio and the ability to operate for up to 10 years on a coin-cell battery."

In addition, Silicon Labs' first Wi-Fi 6 and Bluetooth LE SoC, the fully integrated SiWx917, is designed to be the lowest-power Wi-Fi 6 and Bluetooth LE SoC in the industry, Sogani said. "The SiWx917 is a single-chip solution that is Matter-ready, includes an integrated applications processor and offers industry-leading energy efficiency, making it ideal for battery-powered or energy-efficient IoT devices with always-on cloud connectivity."

Synaptics is focusing on two major industry trends: connecting sensors that are gathering data to the AI systems or devices that are doing the analysis, and making wireless devices easier to use, Bae said.

"First, we're simplifying the integration of AI and wireless through KatanaConnect, which combines our Katana low-power edge AI SoC with our SYN430132 1 × 1 Wi-Fi/Bluetooth combo chip on a tiny module measuring 32 × 32 mm," he said. "Second, our mix of Bluetooth, ULE, Wi-Fi, 802.15.4 and GNSS solutions is unique in the industry. They are proven solutions that simplify the cost-effective and rapid development of IoT connectivity devices. This has clear single-source benefits of both product and design expertise, so we know how to connect IoT devices."

However, Bae said there is more to it than having the silicon and track record. "We're also either already Matter-compliant or are working on it across all our solution stacks so we can ensure users benefit from Matter's promise of a seamless user experience across platforms and interfaces."

A good example of Synaptics' Matter support and high integration is the SYN4381 Triple Combo SoC, which the company claims as the first to combine Wi-Fi 6/6E (802.11ax with extended 6-GHz operation), Bluetooth 5.2 (BT 5.2) with BLE audio and high-accuracy distance measurement, and IEEE 802.15.4 with built-in support for the Thread protocol and Matter application layer. The SoC and its SynFi software simplify product development by providing secure and scalable connectivity between devices across heterogeneous IoT networks, regardless of platform, OEM or brand, the company said. For end users, they get a simplified setup and seamless control across their smart-home devices.

Key differentiators for Synaptics include its robust connectivity and the ability to balance cost and performance, Bae said. "For example, while many offer Wi-Fi/Bluetooth combo solutions, they haven't fully controlled the signaling, and that shows up as glitches in both audio and video."

To solve the problem, Synaptics has developed a proprietary mechanism, which it calls Smart Coexistence, in the 2.45-GHz band. It "carefully manages the Wi-Fi and Bluetooth transmission and reception to avoid lost packets and the inefficiencies of retransmissions," Bae said.

Bae added it is baked into all of its combo chips, including the SYN4381 Triple Combo, as well as the SYN43756 Bluetooth/Wi-Fi combo chip and the SYN43756, a single-chip IEEE 802.11ax 2 × 2 MAC/baseband/radio with integrated Bluetooth 5.2 (with LE Audio).
