Hi, i am on radio 125 wheel when bump on bridge gap rather hard loosing signal about 10 second, is that something could be fix vesc tool, connections are good snd siliconed and using uart.
Remote signal coming on/off is neither something VESC tool manages and can tinker about to my knowledge. What is possible, however, is that the ESC faulted and rebooted during the time the board was dead (which is typically a few seconds). I don’t know if possible now, but would be helpful to look into the ESC fault history or any other sign of it rebooting (trip history?).
Besides that, you gotta make sure every connection is solid in the board (like you did) as well as inside the remote (battery connections particularly). I know that the remote battery leads can be intermittent from vibration/shock.
