Solution for Thermal Printers Using the KT6368A Dual-Mode Bluetooth Chip Module

I. Introduction to the Printer Bluetooth Module

Currently, most mainstream printers do not come equipped with Bluetooth. Due to cost constraints and other factors, many still rely on USB for communication with computers to facilitate data exchange for printing.

In the early days, Bluetooth technology developed slowly, and printer-type products were positioned as high-end, making development quite challenging. For example, a requirement to connect one iOS device and seven Android host devices simultaneously to send print data was nearly impossible to achieve cost-effectively.

Most current module products consist of an MCU paired with a Realtek dual-mode Bluetooth chip. The reason for this combination remains unclear to us.

However, in reality, many products do not require such high specifications. Connecting to a single host device is often sufficient. For scenarios requiring simultaneous multi-device operation, Wi-Fi or 4G versions are typically used instead.

Additionally, modern Windows 10 computers come with built-in Bluetooth drivers, and Bluetooth adapters are readily available and convenient to use.

The early Bluetooth module designs were as follows:

We recommend using the KT6368A dual-mode Bluetooth chip, which enables APP connectivity and data exchange for printers. It comes in an SOP8 package, offering high cost-effectiveness, simplicity, and stability.

II. Detailed Development Guide

1. First, ensure that your Bluetooth printer supports BLE (Bluetooth Low Energy) communication and does not use proprietary protocols, adhering to standard BLE communication protocols.

2. Obtain UUIDs from the Printer Manufacturer

Request the printer's UUIDs from the manufacturer. There are three UUIDs:

Service UUID

TX_UUID (Transmit UUID)

RX_UUID (Receive UUID)

3. Configure the Bluetooth Module Using AT Commands

Enter AT command mode to modify the BLE UUIDs. Update all three UUIDs (Service, TX, and RX).

Set the BLE working mode to Master Mode.

Send the command AT+Z to restart the module.

The UUIDs for the KT6368A are as follows:

Service_UUID: 49535343-FE7D-4AE5-8FA9-9FAFD205E455

TX_UUID: 49535343-1E4D-4BD9-BA61-23C647249616

RX_UUID: 49535343-8841-43F4-A8D4-ECBE34729BB3

III. Test Environment Setup – Meituan Merchant Edition

The Android and iOS platforms operate differently:

Android uses SPP (Serial Port Profile) for communication.

iOS devices use BLE (Bluetooth Low Energy).

The KT6368A chip's internal operation logs and the print data received from the app can be monitored for debugging and verification.

I hasten to add that I don’t think Bernie Sanders is inimical to democracy. I think that’s the big difference between rightwing versus leftwing, that rightwing populism is inherently inimical to democracy. I don’t think leftwing populism is. In fact, I would say that we probably do need a good dose of leftwing populism today to save us, really, from the very damaging and ultimately much more scary rightwing version.

Karine Le Marchand : ce clash que Cyril Hanouna n'attendait pas !

Tandis que Jean-Luc Lemoine faisait ses premiers pas en tant que chroniqueur dans "Les Grosses Têtes" de RTL ce 27 mars, il a reçu un avertissement de sa collègue, Karine Le Marchand, qu'il n'oubliera pas.

"Là c'est pas chez Hanouna"

L'animatrice de "L'amour est dans le pré" l'a épinglé pour son passé dans l'émission Touche pas à mon poste... Malgré de bons rapports avec Cyril Hanouna, elle n'aime pas beaucoup l'émission de C8. Et elle ne s'en cache pas...

Agacée par les violentes critiques qu'elle reçoit régulièrement de Benjamin Castaldi ou Gilles Verdez , elle a prévenu Jean-Luc Lemoine : "Là c'est pas chez Hanouna, donc faut pas dire du mal !". 

Et l'intéressé ne s'est pas laissé intimidé. Il lui a répondu tout de go : "Je sens qu'elle n'a pas digéré certaines choses...", faisant rire tout le plateau. Et Karine Le Marchand de lui assurer : "Non... Pas de toi".

"Il n'aime pas mon émission" La BFF de Stéphane Plaza en a également profité pour enfoncer le...

Here's the dating app for you, based on your zodiac sign

In our Love App-tually series, Mashable shines a light into the foggy world of online dating. It is cuffing season after all.

Picking which dating app will drag you down to hell is no easy task. So why not select one based on the internet's favorite pastime: astrology?

Maybe you should try Coffee Meets Bagel. Perhaps a nice stint on Bumble is in your future. Or maybe you should give Happn a chance. (Yikes.) 

SEE ALSO: 5 of the best dating sites for introverts, wallflowers, and shy people

Whatever your result, feel free to take these suggestions as seriously as you'd like. After all, nothing is written in the stars, especially love. Bleak!

Aquarius: OKCupid

The deep-thinking, logical Aquarius will appreciate OKCupid's literal hundreds of survey questions, instead of being overwhelmed by them.

Pisces: Hinge

With Hinge comes a wide range of flirting opportunities — users can comment on photos, comment on answers, match without messaging, or message directly. Pisces, a truly creative flirt, is sure to excel here.

Aries: Bumble

Aries who are women seeking men will particularly enjoy Bumble. It has the adventurous, quick swipe energy they're into, but since women have to message first, they still get to maintain a sense of control.

Taurus: Coffee Meets Bagel

Tauruses have a reputation for being high-maintenance, but there's nothing wrong with a little pickiness. Coffee Meets Bagel provides a limited number of curated matches every day while still being fairly low-pressure. As far as dating apps go, it's as close to a balanced experience as you're going to get.

Gemini: Tinder

Tinder can feel like the Wild West, but that won't faze a Gemini. Like Tinder, they're a little all over the place. But that just means more possibilities!

Cancer: Wingman

The sensitive Cancer can veer into crisis mode fairly easily, which is why it might be helpful to have a dedicated team of wing-people to help them navigate the online dating realm. Plus, Cancers love friendship.

Leo: Raya

Leos are stereotyped as showboats because they are showboats. What better way to show off than joining an exclusive dating app with a waitlist 100,000 people deep? Also, its nickname is "Illuminati Tinder."

Virgo: The League

Profiles on The League must undergo a pretty intense screening process — including submitting their LinkedIn profile — which is perfect for the fastidious Virgo.

Libra: Happn

Happn, which matches you with people you've crossed paths with IRL, is not not creepy. It's also potentially great for Libras, who have a very healthy appetite for romance but may need a beat to consider: Are they actually crushing on the person from the subway? Or do they just like dramatic eye contact?

Scorpio: Hater

Using Hater, which is predicated on the idea that people will bond over their mutual dislikes, can be a pretty intense experience. Luckily, "intense" is every Scorpio's middle name.

Sagittarius: Zoosk

Zoosk is a large community of over 35 million users, which should play well with a Sagittarius's adventurous spirit and optimism — even when the experience gets a bit overwhelming.

Capricorn: Match

Capricorns have a reputation for enjoying the classics, so Match, which has been around in some form or another since 1995, is a good option for them.

Love. It's in the stars.

WATCH: This slim GPS will track just about anything

L'Oréal Paris : ce mascara à 15€ qui fait mondialement le buzz

Les mascaras L’Oréal Paris ? Plus que jamais une valeur sûre… et ce, quelle que soit la problématique liée à nos cils.
