BFB F.A.Q.
No reply?
I’m connected, i switch in binary data mode (with at^sbfb=1) and send some BFB data, and then nothing happens, no answer, what’s wrong ?
If something goes wrong there won’t be an answer.
may i change bauds-rate or something in this mode ?
You may do that, but I discourage you from doing it. It’s complicated.
Send <01><10><0B><C0>115200<0D><D2><2B>
Answer is <01><0A><0B><CC>115200<0D><D2><2B>
the phone must give an answer for each frames, not ?
Try the init frames.
It’s <02><01><03><14> the answer should always be <02><02><00><14>
how to switch back the phone in “AT” mode ?
There is a cancel sequence.
