• Thank both, that's very helpful! I have got the first 2 working, but I think I'm using NRF.getAddress() wrong, as I'm getting the following error: "Uncaught Error: Function "getAddress" not found!"

    My code is as follows:

    Bluetooth.println('BOARD:'+process.env.B­OARD); // works
    Bluetooth.println('SERIAL:'+getSerial())­; // works
    Bluetooth.println('MAC:'+NRF.getAddress(­)); // does not work
    

    Am I doing anything obviously wrong? Does NRF need to be used differently?
