Hacking EV BLDC Motor Controler Protocol

[Piwencjusz]

Hello, I am writing here because I bought a motor controller and I am trying to see how it works and communicates with the display. I know its pinout and I know that after connecting the power and turning it on, it sends 9 bytes in the uart baud 115200 protocol, but that's all I have or someone has had to do with something like this and know what the protocol is?

Hello, have you figured out this controller? I have the same one and am looking for information on how to make it work.

See this thread about the KT controller, where some figured out the protocol.

It won't apply to your model. I don't think anyone else is going to look at the firmware on an anonymous $29USD black box, but you might find some like minded people.

KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

This OpenSource firmware/embedded software runs on the BMSBattery S/Kunteng KT motor controllers. The main advantages of this controllers are: 1. sine wave/"FOC": motors run silent and very efficient 2. cheap: starting at 20€ 3. widely available: many online shops sell them and ship to worldwide...
