BG96: Cannot change AT (UART1) BAUD Rate

I wish to set UART1 to 921600 BAUD. I have tried the following commands as per the documentation however after power cycling the BG96 I find that the UART1 BAUD rate remains at the default rate of 115200.

pls pay more attenttion to the below item :slight_smile:

  1. only the uart port can be config , USB-AT port /modem port can not be config
    2, the host baut rate should be same as the TE-A
