It's nothing about special code, program logic works. But even a simple serial echo program dosen't work.
Baud rate tried 115200, 19200, 57600.

That will help you to figure out who is not talking at proper time.

Both are transmitting well. But ESP dosen't receive for some reason. This is the problem.
