Extra Characters from UART after command transmission

Open dcolcott opened this issue 3 years ago • 1 comments

Hi There, I have a ESP32 sending commands to the SERVO42c using the UART interface (trying at various BAUD Rates). After each command transmitted the expected result (Serial Driver ID, [hex response] t_chcksum) is returned as expected but then up to 20 or so extra characters are received on the UART Rx

Any idea why this is happening?

OK, solved my own problem here.

For anyone else using ESP32 UART for this (or other) connection, the RX pin is floating and needs to be pulled-up as per: https://github.com/espressif/esp-idf/issues/1477
