USSD AT Command doesn't work
« on: March 29, 2013, 07:53:08 am »
Hello!


I'm using GSM demo. In "Direct AT Command", I type: at+cusd=1,"*101#",15<cr>
It replies: Error.

But when I type : at+cusd=1,"4d5f",15<cr>
It returns: OK.
For example if I convert *101# to hex string, the command will be : at+cusd=1,"2a31303123",15<cr>
It returns: OK, but I don't see any result, ex: Your balance is: 1234,50usd :'(

Any characters between 2 quotes will result -> Reply: Error , if it not a hex string value.

Hello

It seems like command returns OK after that (seconds later) device receives service notification (like sms report) with necessary information.
We will check builtin Huawei gsm driver implementation.
