This tutorial is based on Real-Time GPS Monitoring using M5Stick C (ESP32) with the help of Qubitro's GPS Mapping System. Things used in this project Hardware componentsM5Stack M5StickC ESP32-PICO Mini IoT Development Board×1M5Stack Mini GPS/BDS Unit×1Software apps and online servicesQubitroArduino IDEGoogle Colab Story In this DIY tutorial, we are going to build an IoT-based GPS Location tracker using M5Stack GPS Unit and M5Stick C. Here, we have used Qubitro as a Cloud platform to Map the GPS Coordinates, and this coordinates will be mapped by using Google Colab with the help of simple python script. Hardware Connections: Just kidding, there is no hard-wiring in this tutorial, simply connect the GPS unit with M5StickC, that's all. Let's Compile: I used Tiny GPS library, It's very simple to use with maximum GPS units, and all the Cloud Integration could be found in the Qubitro documentation page and upload the below Qubitro_Gps.ino sketch to the M5StickC. #include #include #include #include TinyGPSPlus gps; HardwareSerial ss(2); float Lat, Lng; String lat_str , lng_str; int sat, battery = 0; float b, c = 0; // WiFi Client WiFiClient wifiClient; // Qubitro Client QubitroMqttClient mqttClient(wifiClient); // Device Parameters char deviceID[] = "Qubitro-Device-ID"; char deviceToken[] = "Qubitro-Device-Token"; // WiFi Parameters const char* ssid = "ELDRADO"; const char* password = "amazon1234"; void setup() M5.begin(); M5.Lcd.setRotation(3); M5.Lcd.fillScreen(BLACK); M5.Lcd.setSwapBytes(true); M5.Lcd.setTextSize(1); M5.Lcd.setCursor(7, 20, 2); M5.Lcd.setTextColor(TFT_GREEN, TFT_BLACK); ss.begin(9600, SERIAL_8N1, 33, 32); wifi_init(); qubitro_init(); void loop() while (ss.available() > 0) if (gps.encode(ss.read())) if (gps.location.isValid()) void wifi_init() // Set WiFi mode WiFi.mode(WIFI_STA); // Disconnect WiFi WiFi.disconnect(); delay(100); // Initiate WiFi connection WiFi.begin(ssid, password); // Print connectivity status to the terminal Serial.print("Connecting to WiFi..."); while (true) delay(1000); Serial.print("."); if (WiFi.status() == WL_CONNECTED) Serial.println(""); Serial.println("WiFi Connected."); Serial.print("Local IP: "); Serial.println(WiFi.localIP()); Serial.print("RSSI: "); Serial.println(WiFi.RSSI()); M5.Lcd.setTextColor(RED); M5.Lcd.setCursor(0, 8); M5.Lcd.printf("Network Connected"); break; void qubitro_init() char host[] = "broker.qubitro.com"; int port = 1883; mqttClient.setId(deviceID); mqttClient.setDeviceIdToken(deviceID, deviceToken); Serial.println("Connecting to Qubitro..."); if (!mqttClient.connect(host, port)) Serial.print("Connection failed. Error code: "); Serial.println(mqttClient.connectError()); Serial.println("Visit docs.qubitro.com or create a new issue on github.com/qubitro"); Serial.println("Connected to Qubitro."); M5.Lcd.setTextColor(RED); M5.Lcd.setCursor(0, 25); M5.Lcd.printf("Uplink Established"); mqttClient.subscribe(deviceID); delay(2000); M5.Lcd.fillScreen(BLACK); void batteryLevel() c = M5.Axp.GetVapsData() * 1.4 / 1000; b = M5.Axp.GetVbatData() * 1.1 / 1000; // M5.Lcd.print(b); battery = ((b - 3.0) / 1.2) * 100; if (battery > 100) battery = 100; else if (battery < 100 && battery > 9) M5.Lcd.print(" "); else if (battery < 9) M5.Lcd.print(" "); if (battery < 10) M5.Axp.DeepSleep(); Serial.print("battery: "); Serial.println(battery); void printDate() Serial.print(gps.date.day()); Serial.print("/"); Serial.print(gps.date.month()); Serial.print("/"); Serial.println(gps.date.year()); // printTime() formats the time into "hh:mm:ss", and prints leading 0's // where they're called for. void printTime() Serial.print(gps.time.hour()); Serial.print(":"); if (gps.time.minute() < 10) Serial.print('0'); Serial.print(gps.time.minute()); Serial.print(":"); if (gps.time.second() < 10) Serial.print('0'); Serial.println(gps.time.second());

Data Visualization: Once you upload the code to M5Stick C, go to your Qubitro Device Portal and you can see the create a chart tab. Qubitro Device Page After clicked the Creation a Chart tab, select chart type as map and select the data variables ( like longitude, latitude as per the tabs) Create a Chart (Map) page That's all, now you are good to go, navigate to the Analytics area, and you can see the uploaded GPS Co-ordinates are mapped. Mapped Co-ordinates Mapping with Google Colab: If you want to map your whole location data, here I'm used python script which can phrase GPS co-ordinates and map. First you have to download the Data from Qubitro Portal by the format of CSV (now in Beta Stage), then log in to google colab and import the below python script. Import the downloaded CSV files from the Qubitro Portal. Execute the blocks one by one (make sure to rename the files in both script and files). So it's very simple and easy to use python script, Once you executed the final block you can find the logged map (sample CSV file uploaded in the GitHub). Device in action Code Qubitro GPS Mapping # import libraries + wardriving data import pandas as pd wd = pd.read_csv ('Neo-Baby-Walk.csv') # import list of all GPS Data from CSV file to pandas data frame wd.sample(100) # sample 10 random devices from dataset # len(wd) # number of detected devices # start mapping devices import folium from folium import Map, Marker basic_map = folium.Map(location=[33.675899,-117.602236 ],zoom_start=17) # manually pick scope of map folium.PolyLine(wd[['Latitude', 'Longitude']].values.tolist(),line_opacity = 0.5, weight = 4).add_to(basic_map) # plot route display(basic_map) https://github.com/Kyoot-Create/Qubitro

Flutter is a new mobile app SDK to help developers and designers build modern mobile apps for iOS and Android.

Features of Flutter:-

1. Fast development

Flutter’s hot reload helps you quickly and easily experiment, build UIs, add features, and fix bug faster. Experience sub-second reload times, without losing state, on emulators, simulators, and hardware for iOS and Android.

2. Expressive, beautiful UIs

Delight your users with Flutter’s built-in beautiful Material Design and Cupertino (iOS-flavor) widgets, rich motion APIs, smooth natural scrolling, and platform awareness.

3. Modern, reactive framework

Easily compose your UI with Flutter’s modern reactive framework and the rich set of the platform, layout, and foundation widgets. Solve your tough UI challenges with powerful and flexible APIs for 2D, animation, gestures, effects, and more.

class CounterState extends State<Counter> { int counter = 0; void increment() { // Tells the Flutter framework that state has changed, // so the framework can run build() and update the display. setState(() { counter++; }); } Widget build(BuildContext context) { // This method is rerun every time setState is called. // The Flutter framework has been optimized to make rerunning // build methods fast, so that you can just rebuild anything that // needs updating rather than having to individually change // instances of widgets. return new Row( children: <Widget>[ new RaisedButton( onPressed: increment, child: new Text('Increment'), ), new Text('Count: $counter'), ], ); } }

4.Access native features and SDKs

Make your app come to life with platform APIs, 3rd party SDKs, and native code. Flutter lets you reuse your existing Java, Swift, and ObjC code, and access native features and SDKs on iOS and Android.

Accessing platform features is easy. Here is a snippet from our interop example:

Future<Null> getBatteryLevel() async { var batteryLevel = 'unknown'; try { int result = await methodChannel.invokeMethod('getBatteryLevel'); batteryLevel = 'Battery level: $result%'; } on PlatformException { batteryLevel = 'Failed to get battery level.'; } setState(() { _batteryLevel = batteryLevel; }); }

5.Unified app development

Flutter has the tools and libraries to help you easily bring your ideas to life on iOS and Android. If you don’t have any mobile development experience, Flutter is an easy and fast way to build beautiful mobile apps. If you are an experienced iOS or Android developer, you can use Flutter for your views and leverage much of your existing Java/ObjC/Swift investment.
