Jan-Marcel Dietrich	73fe564321	Remove characteristic in GATT Client unsubscribe() if it's the last subscriber GATT Client's subscribe() adds the characteristic itself as subscriber. Therefore the characteristic has to be removed in unsubscribe(), if it's the last subscriber. Otherwise the clean up does not work correctly and the CCCD never is set back to 0 in the remote device.	2024-10-30 07:34:22 +01:00
