On the Dart side you'd better call like: https://github.com/woodemi/notepad_core/blob/b0e329f3d6e02f14f8a0e5e48a6ddb48e026b658/notepad_core/lib/woodemi/WoodemiClient.dart#L245-L256
const CODE__SERV_BATTERY = "180f";
const CODE__CHAR_BATTERY_LEVEL = "2a19";
const SERV__BATTERY = "0000$CODE__SERV_BATTERY-$GSS_SUFFIX";
const CHAR__BATTERY_LEVEL = "0000$CODE__CHAR_BATTERY_LEVEL-$GSS_SUFFIX";Common service/characteristic list
