writeCharacteristicWithResponse method

Future<void> writeCharacteristicWithResponse(QualifiedCharacteristic characteristic, { required List<int> value, })

Writes a value to the specified characteristic awaiting for an acknowledgement.

The returned future completes with an error in case of a failure during writing.

This method assumes there is a single characteristic with the ids specified in characteristic. If there are multiple characteristics with the same id on a device, use resolve to find them all. Or use getDiscoveredServices to select the Services and Characteristics you're interested in.
