You are trying to write 1 to the characteristic itself. The notification enable is always the handle after the target characteristic.
Do this:
ConfigHndl = ch.valHandle + 1
p.writeCharacteristic(ConfigHndl , (1).to_bytes(2, byteorder='little'))
from bluepy.
Did this fix the problem?
Also, it's not generally reliable to pick out indices into lists of values ( srvs[2], chs[1] etc.) because bluepy doesn't guarantee the order (see e.g. http://stackoverflow.com/questions/526125/why-is-python-ordering-my-dictionary-like-so for some of the background to this).
In general, you either have to find the services / characteristics you want by UUID, or consult the documentation for the BLE peripheral to discover the handles for the characteristics you're trying to read or write.
