The peripheral manager providing this information.
The remote central device that subscribed to the characteristic’s value.
The characteristic whose value has been unsubscribed from.
This method is invoked when a remote central device unsubscribes from the value of one of the local peripheral’s characteristics, by disabling notifications or indications on the characteristic’s value. You should use the invocation of this method as a cue to stop sending the subscribed central updates as the characteristic’s value changes.
