Puck Advertising Private Characteristic and r/w

Update:

Im done with second characteristic and it works. But with notify it stocks.

Here is the Code:

NRF.setServices({
  "b0d0cdff-56fa-4bee-b611-874c82f0c313": {
   "9ed52c1b-73e4-47a9-b335-8e12cfa22fdc": {
      value : 0,
      writable : false,
      notify:true
    }
  }
}, { uart : false });

And the update code:

NRF.updateServices({
  "b0d0cdff-56fa-4bee-b611-874c82f0c313" : {
    "9ed52c1b-73e4-47a9-b335-8e12cfa22fdc" : {
      value : 1,
      notify: true
    }
  }
});

The state switch and I can set Notify into the BLE App but no notification received.
