• Is it possible that you're still connected to the slave device with your PC?

    Espruino BLE devices can only have one device connected to them at a time, so if you're connected with your PC, the 'master' device won't be able to connect.

    Also, if you stay connected with the 'master' you could change the code to:

        }).catch(function(e) {
          digitalPulse(LED1, 1, 500); // light red if we had a problem
          busy = false;

    And you might be able to see what error it is complaining about
