Query the device name (BLE characteristic UUID 0x2a00) of a Bluetooth® Low Energy device.

Syntax

bleDevice.deviceName()

Parameters

None

Returns

Device name (as a String).

Example


  // begin initialization
  if (!BLE.begin()) {
    Serial.println("starting Bluetooth® Low Energy module failed!");

    while (1);
  }

  Serial.println("BLE Central scan");

  // start scanning for peripheral
  BLE.scan();

  

  BLEDevice peripheral = BLE.available();

  if (peripheral) {
    // ...

    Serial.println("Connecting ...");

    if (peripheral.connect()) {
      Serial.println("Connected");
    } else {
      Serial.println("Failed to connect!");
      return;
    }

    // discover peripheral attributes
    Serial.println("Discovering attributes ...");
    if (peripheral.discoverAttributes()) {
      Serial.println("Attributes discovered");
    } else {
      Serial.println("Attribute discovery failed!");
      peripheral.disconnect();
      return;
    }

    // read and print device name of peripheral
    Serial.println();
    Serial.print("Device name: ");
    Serial.println(peripheral.deviceName());
    Serial.print("Appearance: 0x");
    Serial.println(peripheral.appearance(), HEX);
    Serial.println();

    // ...
  }
