What is your problem?

I'm switching to flutter_blue_plus from flutter_reactive_ble, in flutter_reactive_ble i could read a value from the ble device in very simple way, for example to read the battery value is going so:

final characteristic = QualifiedCharacteristic(serviceId: serviceUuid, characteristicId: characteristicUuid, deviceId: foundDeviceId);
final response = await flutterReactiveBle.readCharacteristic(characteristic);

But in flutter_blue_plus I can't read the battery value in this way, as far as I understand I MUST to discover all the services, and then all the characteristic and then find out the battery characteristic and call it....... a very long way.

Is there a way to call it directly like in flutter_reactive_ble
