So if just if anyone at home is interested in testing out the new command injection firmware it is intended for a ESP32 (i.e. Adafruit Huzzah32) The reason being is it has 2 hardware serial ports. One of the ports is sending to the scooter the commands over Serial1. The other is being used for debugging and sending commands to the ESP32 i.e. Serial
You can do this with an Arduino Nano but it would need to be updated with a SoftSerial command to work.
