I labeled the Arduino with the BLE "setlocalname" as node 1 to distinguish it from the other nodes. I send the pitch, roll, and heading floats calculated by the Arduino to the Flutter app via BLE and display it on the app to verify its accuracy. Each value has to be updated manually in the app to see it, but the values are added automatically to the "floatlist" in the Flutter widget.dart program.
