read 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 FlutterReactiveBle.characteristicValueStream before the actual read response arrives (due to the design of iOS BLE API).
Implementation
Future<List<int>> read() {
_assertValidity();
return _lib._connectedDeviceOperator.readCharacteristic(_ids);
}
