Motor stutter due to UART connection?


following issue: maytech remote works fine in ppm mode. Once I add the tx/rx connection I can see the data in the remote, but the motor is now stuttering at 0-95% duty. I switched the remote&receiver (I have ordered two) and everything is stutter with UART connection.
If I add metr to the faulty receiver everything is also working fine. Did somebody else faced this issue? I have seen lately some stutter motor issue, I would advice to test your setup first without UART communication towards receiver


Does it stutter in current control mode as well? I don’t use duty control because of maybe this issue… Might be the uart vesc is only sending integers or something.
