  Hello everyone,
  currently I'm developing an application for my bachelor's thesis and I want to control the watch via BLE on my phone.

  I have already established a connection and can discover and read the characteristics of the watch. What I want to achieve is also writing to a characteristic and reading it with the watch (to turn on/off the Heart Rate Sensor etc.). Is there a function which monitors the watch's writable characteristics/services? And if not how should I approach this? (Or is this even the right way to do it? )
  Much thanks in advance.. If you need further info / code I'm happy to provide it.

  Greetings

  EDIT: I've found it :)

  NRF.setServices({
    0xBCDE : {
      0xABCD : {
        writable : true,
        onWrite : function(evt) {
          digitalWrite([LED3,LED2,LED1], evt.data[0]);
        }
      }
    }
  });
