Excellent post Sir!!!🙏👌

how to export the data to csv format?

#include // Bluetooth Library #include // Pressure Sensor Library #include // Temperature Sensor Library #include // Magnetometer Sensor Library // Initalizing global variables for sensor data to pass onto BLE String p, t, m; // BLE Service Name BLEService customService("180C"); // BLE Characteristics // Syntax: BLECharacteristic (, , ) BLEStringCharacteristic ble_pressure("2A56", BLERead | BLENotify, 13); BLEStringCharacteristic ble_temperature("2A57", BLERead | BLENotify, 13); BLEStringCharacteristic ble_magnetic("2A58", BLERead | BLENotify, 20); // Function prototype void readValues(); void setup() { // Initalizing all the sensors HTS.begin(); BARO.begin(); IMU.begin(); Serial.begin(9600); while (!Serial); if (!BLE.begin()) { Serial.println("BLE failed to Initiate"); delay(500); while (1); } // Setting BLE Name BLE.setLocalName("Arduino Environment Sensor"); // Setting BLE Service Advertisment BLE.setAdvertisedService(customService); // Adding characteristics to BLE Service Advertisment customService.addCharacteristic(ble_pressure); customService.addCharacteristic(ble_temperature); customService.addCharacteristic(ble_magnetic); // Adding the service to the BLE stack BLE.addService(customService); // Start advertising BLE.advertise(); Serial.println("Bluetooth device is now active, waiting for connections..."); } void loop() { // Variable to check if cetral device is connected BLEDevice central = BLE.central(); if (central) { Serial.print("Connected to central: "); Serial.println(central.address()); while (central.connected()) { delay(200); // Read values from sensors readValues(); // Writing sensor values to the characteristic ble_pressure.writeValue(p); ble_temperature.writeValue(t); ble_magnetic.writeValue(m); // Displaying the sensor values on the Serial Monitor Serial.println("Reading Sensors"); Serial.println(p); Serial.println(t); Serial.println(m); Serial.println(" "); delay(1000); } } Serial.print("Disconnected from central: "); Serial.println(central.address()); } void readValues() { // Reading raw sensor values from three sensors float x, y, z; float pressure = BARO.readPressure(); float temperature = HTS.readTemperature(); if (IMU.magneticFieldAvailable()) { IMU.readMagneticField(x, y, z); // Saving sensor values into a user presentable way with units p = String(pressure) + " kPa"; t = String(temperature) + " C"; m = "X:" + String(x) + ", Y:" + String(y); } }

is the following code, the correct one?

great video prof ...now once i receive data from the sensors how can i control like if the temperature is 20'c and am interested on 30'c .is it possible i control a thermostat using this sensor data automatically ?

Great video, just the thing I was looking for to transmit data to my android phone. I was able to see the data on my phone, but could not figure-out how to plot the data. If you could (or anyone), please, provide instructions on how to plot the data. Thanks, Vinod

@Kumar I have a little problem with my coding, did try a lot of stuff, but sadly cannot make this board be recognized by PC (Asus USB-BT400 dongle) as HID device (joystick with 6 axis). I've tried to simply connect to PC via BT/BLE and still no go for sending data. If you don't mind, please make a simple example of this board using BT/BLE for connecting to PC, would like to have it as virtual COM, or HID device. Thanks and keep it up...

graet video, i'm using a similar sensor to this and it has BLE connection too. I wonder if there could be a way to sent data from the device directly to Windows using BLE connection?

can you please show how to send simple data from peripheral ble33 device to central ble33 device using the ble setup? simple code:( i just dont see anywhere

I can not find the code in the github link, is there any shorcut? I will be gratefull

excuse me Profesor, I need to transer data from BLE 33 sense to Google Firebase, How is it?

Hello, where can I find the code please ?

Hello Sir, please share the code link

I get an error: exit status 1 Compilation error: redefinition of 'void setup()'
