This value is
true if you enabled notifications or indications for the characteristic by successfully calling the
set method of the
CBPeripheral class. In this case, the peripheral updates its connected central that whenever the characteristic’s value changes.
If the value of the property is
false, notifications (or indications) aren’t enabled for the characteristic, and the peripheral doesn’t update its connected central when the characteristic’s value changes.
