Re: bluez/android

Hi Szymon,

 Sorry for posting with ML, my mistake.

Thanks for the information.  Again, I was trying to find where the
unknown AT Commands are coming;
I tried to catch @ static void at_cmd_unknown(const char *command,
void *user_data);
But, no luck, no AT commands are caught there.  If you can let me
know, where all the AT commands will be handled would be of great help
( unknown - so that I can handle then)

ManYThanks
Prabhu

Hi Szymon,

   Thanks for your reply. I was debugging further, I noticed that
while connecting at service level, there is CIND callback
(cind_cmd_cb) is coming which is for Call Indicator AT CMD.
I am curious to know, how it is happening, which can help me to
understand and  try for other call backs.

Please don't top-post on ML.

As for your question: HFP HAL has methods that should be called as a reply for
some callbacks ie for cind that would be cind_response. You can check
"android/hardware/bt_hf.h".

Yet, Android HAL is rather lowlevel interface not recommended for direct use.
If for whatever reason you are stuck with it I suggest checking Android
Framework source code as this (and header comments) is the only documentation
you get for it.

 This is with respect to HFP profile.

While I pressed the Button on my HF device, service level connection
is happening - BTHF_STATE_CONNECTED is coming.

But next callbacks are not coming on pressing of buttons - like voice
recognition.

Can any body help me

HFP is a bit special since BfA provides only part of the implementation
and
rest is implemented in Android Framework. When HF device is connected SLC
creation must happen. Most likely your HF device is sending some AT
commands and you must response to those as per HFP specification. Only
when all required SLC AT commands are handled state will be set to
BTHF_STATE_SCL_CONNECTED. This is normally handled by Android Framework
but if you are using haltest you must handle those on your own.

For details on how to setup SLC I recommend HFP specification lecture.
