Hello, I am Konstantin. I bought a fsesc (3-12s Esc PWM Speed Controller Mini FSESC4.20 50A Base on VESC® 4.12 with Aluminum Anodized Heat Sink Flipsky) and it works very well with my motor (I used the arduino to controll it and the VescTool to see some graphs of the values), but now I have a problem. I need to get the values (like rpm, current...) using UART and not USB like before, but when I connect the FSESC to my Arduino and try to get the values, I always get empty data. Maybe you have a user guide or something like interface describtion.
Maybe I connect the cables wrong or something like that.
