• Oh, great. Thanks for the quick response. Switching Bluetooth on and off actually solved the problem!

    I found a note in the meantime that the Bluetooth SIG requires a service 0x1801: { // generic attribute service with charactersitic 0x2A05: { // service changed characteristic to be present (and I assume with value true) if the services on a device can change.

    I tried to set this, as part of my code using

      0x1801: { // generic attribute service
        0x2A05: { // service changed characteristic
          notify: true,
          readable: true,
          value : [true]

    but this didn't produce any effect. I suppose at that point it's already too late? Would it be possible to put that into the default profile?
