Subscribing to single notification characteristic and cannot unsubscribe

[imranmoezkhan]

I have a service with a number of characteristics and I'm trying to use pygatt to subscribe to a particular notification characteristic, but it seems to be subscribing to all of them:

p=adapter.connect("6C:ED:CA:81:DE:7D", address_type=ADDRESS_TYPE)
INFO:pygatt.backends.gatttool.gatttool:Connecting to 6C:ED:CA:81:DE:7D with timeout=5.0
p.subscribe("6e500002-b5a3-f393-e0a9-e50e24dcca9e")

Also, I seem to be getting notifications even after unsubscribing to the characteristic:

Is there something I'm doing wrong?
