How can I use baud rate other than 115200 bps for application download? You must send the below command for the first time at 115200 bps, as the module is shipped with baud rate at 115200 bps. 1) AT+CFG 520 XXXX where X is desired baud rate. 2) Instead of calling AT &F *, you must send "AT &F 1" which will only clear the file system.
