[Solved] How to Control Dreame H11 C2010 M13-C Motor and Pump with ESP32?

Hi,

I own a Dreame H11 mop I am trying to remove all the control board and replace with my own on esp32, it has 2 motors and a water pump.

One motor is on 18V simple in operation 2 cables from turning the mop shaft at the bottom.
Pump I have not tested do not know what voltage it has.
The second motor c2010 m13-c the largest 150W 21.6V has two thick cables connected directly on the board with the 21.6V batteries and additionally connects to the board via 2 cables on the board marked TX D+, RX is free, i.e. only the signal is sent from the board to the motor via TX D+ does not have to be connected, it fires on one cable, I suspect this is ground.

I try to read via usb serial tty at 115200 and only screams.
How to drive such a motor correctly?
It does not have 3 thick cables only 2 thick and 2 thin.

I tried to drive esp32 pwm 50hz gpio32 does not start and just this one cable to the board and it starts the motor


When I connect esp32 uart RX under this cable it catches when the motor starts

pojedynczy packet is x00 and the quantities seem to increase in power, first gradually from a few then more and more

the voltage on these cables is below 0.2V

is this some kind of communication or is this what a normal PWM can look like?

I knocked that controller out and gave my 3-phase BLDC and it laughs without a problem.
