ESP32BLE.h

An ESP32 class for BLE using the Arduino framework.

A simple header file for easily setting up a Bluetooth Low Energy service for sending and receiving data with ESP32.

Usage

Just drop the ESP32BLE.h file into your project.

To simply setup the service:

ESP32BLE bluetooth;
void setup() {
  bluetooth.setup("Example");
}

To trigger a function upon receiving data:

ESP32BLE bluetooth;

void onReceiveData(const String newValue);

void setup() {
  Serial.begin(115200);
  bluetooth.setup("Example", onReceiveData);
}

void onReceiveData(const String newValue) {
  Serial.println("Received data: " + newValue);
}

To send data:

int i = 0;
void loop() {
  i += 1;
  bluetooth.send(i);
  delay(1000);
}
