Hi,
i am just starting to use a A7 GSM/GPRS module form AI-THinker. I have it up and running but i really need to change the Baud rate. So i did
AT+IPR=9600
AT&W
As far as i understand this should save the configuration. But when i restart the module, it is set to 112500 baud again.
What am i doing wrong?
Cheers and thanks a lot for help!!!
The AT&W command stores the current configuration to user defined profile so if you only send this:
AT&W
You'll get an error. Then you need to specify a profile after the command (there is only one profile that is 0) so:
AT&W0
It returns OK.
PS: I recommend you to download and view this PDF about AT commands for the A6 module (it will pretty similar to the A7)
