Its default baud rate is 115200.
I want to change it to 9600 baud rate.
I tried to change by AT+CIOBAUD? but it returned ERROR.
Then i tried to change directly by AT+CIOBAUD=9600. Buad rate got changed but after reset or power on, it again goes to its default baud rate 115200.
Please help me how to change and save baud rate to 9600 parmanently.
