Is it possible to extract the firmware from the device and replay it so as to imitate an IOT.?

Hi
I removed everything electronic from the scooter, and only used the controller that I linked

Only cut the two bigger wires from the stock controller :
-The 9-pin juliet : 6 smaller ones are the hall sensor, 3 bigger one are the motor phase
-The power cable

To use the stock battery I tore it appart, and bypassed the BMS for discharge function, wired the positive directly on the cell #13
For charging it is still protected by the BMS

Oh and I also got two other scooters, and I'm currently developping a two-motors version :twisted:

Took a rear wheel, cut the front fork to get the motor inside
Already wired the two controllers on the same throttle

Just need to repaint it and put everything back together
I think that it will be nut :twisted: :twisted: :twisted:
Hello, how you conturn the bms battery ?

Or do you know how to import the CSV-file to an Arduino Sketch?

Thanks for your Replies,
