The module do not support auto baud rate detection. If you do not know the Baud rate of the module you can try to read back the ‘>’ value when pushing CONFIG low for different host baud rates. When you detect ‘>’ you know that the host baud rate is correct. Alternatively you can measure the ‘>’ duration using a oscilloscope and estimate the baud rate of the module.
