Hi, Please provide your code which is returning the characteristic result.
Thanks

I only used the onReadRequest
funtion from the echo example. Apparently adding self._updateValueCallback = None
fixed the issue.
I also tried using the callback
method from the pizza example (onReadRequest) callback(Characteristic.RESULT_SUCCESS, data);
but that gave me some errors regarding the data (I defined data the same way it has been set in the class itself).
Last problem is that the descriptor doesn't work unless I put the uuid and value into a dict. This however produces the same TypeError when doing a read request for the descriptor (which I tried with BLE Scanner)
I am trying to get the characteristics using web bluetooth, but I receive this error when the javascript calls the service.
