How change UART baud rate in WP76xx?

1

Hi,

How could I change UART baud rate which is in the mangOH-yellow external card ?

2

Do you mean UART1?
What do you set for AT!MAPUART?
are you using it in AT command mode? If yes, you might try AT+IPR to change baud rate

3

I set at!mapuart=17,1

You mean like it “AT+IPR=9600” ?

4

Then this is in data mode
You can try the following for setting baud rate to 115200:

stty -F /dev/ttyHS0 raw 115200 -crtscts 
microcom /dev/ttyHS0 -s 115200

Hi @jyijyi ,

Thanks for your reply.

I want to know if I only want to set baud rate “stty -F /dev/ttyHS0 raw 9600” ?

How to I save the setting?

you don’t need to save the setting
just set the baud rate when you open the port

Hi @jyijyi ,

But I want to save the setting , because I sometimes will reboot.

but after reset, you still need to type those commands to open the port, right?
