#94566 Same problem; different root cause
I used a delay() that caused WDT timeout and return the same message.
I replaced delay() with an if() statement in order to let loop() run freely
Problem solved without bothering about baud rate (it runs perfectly at 115200!) and pins state

I use a nodeMCU but I'm sure this applies to any ESP implementation
