Thank you so much @wolph. I completed overlooked the fact that the baud rate might be the problem. I just tried with an ESP32-WROOM chip (was getting the same error message on it) and it worked fine. Shall try with another TX Ultimate switch later.

Anybody ever get the sound to be as loud as the stock firmware. mine works but its very , very low.
