Our streets are becoming litter with high technology joy. These forgotten scooter must be reverse engineer and given the love they deserve.

So when I type in commands into my remote for ESP32 the motor controller spits back hex data. It easier on the eyes in decimal so here a little to look at

Keep alive command

19 38 20 0 44 213 0 82 0 0 80 0 0 7 0 0 255 1 153 186 0 158 0 0 0 0 0 0 32 0 2 100 17 16 16 18 255 255 255 148 127

Turn off

19 38 20 0 44 213 0 82 0 0 80 0 0 16 0 0 255 1 153 186 0 158 0 0 0 0 0 0 32 0 2 100 17 16 16 18 255 255 255 148 1

Notice the highlighted numbers is on and off. Other commands seem to change the last third fourth and fifth digits. Also adds a bunch more data to the response.

19 38 20 0 44 213 0 82 0 0 80 0 0 16 0 0 255 1 153 186 0 158 0 0 0 0 0 0 32 0 2 100 17 16 16 18 255 255 255 202 197 255 255 255 255 255 255 3 255 0 154 36 255 20 162 51 255

The last digit in the string is the checksum Im guessing.
