readCharacteristic method
Reads the value of the specified characteristic.
The returned future completes with an error in case of a failure during reading.
Be aware that a read request could be satisfied by a notification delivered for the same characteristic via characteristicValueStream before the actual read response arrives (due to the design of iOS BLE API).
Implementation
Future<List<int>> readCharacteristic(
QualifiedCharacteristic characteristic) async {
await initialize();
return _connectedDeviceOperator.readCharacteristic(characteristic);
}
