Connecting a ESP32 devkit v1 to Flipsky fsesc75100

[LankoG]

I am trying to connect esp32 with a flipsky vesc, but cannot get esp to work. I connected it only through UART because I do not have CAN bus transceiver.

For UART to work you'll have to rebuild the firmware with CANBUS_ONLY commented out in config.h

Otherwise CANBUS is used.

I already did that, also tried to change [platformio] default_envs = nodemcu-32s, but nothing worked. I am using vs code to upload the code with platformio, but don't think there is anything wrong there.

Ok, did you check that UART is enabled in VESC tool?
Do your VESC and ESP share a common ground?
Using a common ground is important.

[LankoG]

yes when I used just the VescUart library it was able to print the data to the terminal

I tried reinstalling the source code and now I get this error:

@LankoG, you also need to disable CANBUS_ENABLED too
