Is there a way to change the bluetooth name of my board?
It’s “Arduino” and is not affected by BLE.setLocalName(“insert_name”);

Hi there,
Do you mean the Advertised name that would show up in a scan or the device name of the service? there are two. :smiley:

Here
I use this code to make the advertise name be what I want plus the Uniquies serial of each Xiao

void goblu(){
// begin BLE initialization
  if (!BLE.begin()){
    Serial.println("starting Bluetooth® Low Energy module failed!");
    while (1);
  }
  get_id_address(mac_address);
  sprintf(buffBle, "Xiao %02lX%02lX",mac_address[0],mac_address[1]);
    // set advertised local name and service UUID:
  BLE.setLocalName(buffBle);
  BLE.setAdvertisedService(ledService);
  // add the characteristic to the service
  ledService.addCharacteristic(switchCharacteristic);
  // add service
  BLE.addService(ledService);
  // set the initial value for the characeristic:
  switchCharacteristic.writeValue(0);
  BLE.advertise();
  //get_id_address(mac_address);
  //sprintf(buffBle, "Xiao %02lX%02lX",mac_address[0],mac_address[1]);//Serial.println("BLE Peripheral");
}

Yes, but when you change it you cannot change it again, you need a master Reset !
