Re: [PATCH v2 0/9] HSP profile implementation
Hi Frederic,
2011/3/17 Frédéric Dalleau <frederic.dalleau(a)linux.intel.com>:
This patch will start providing an HSP profile implementation
in oFono. This is work in progress, and based of what was done for
HFP profile. Finally added the audio connection, that will provide
a base for discussion. To avoid emulator depend upon btio, there is
a callback fom the emulator to the hsp plugin to connect audio,
Some question remains :
* How should pulse audio be notified?
I suppose we should use the Media API to notify PA, it is already
upstream, in that case oFono doesn't need to deal with SCO at all. If
that is the plan then I suggest we first define a D-Bus spec on how to
signal things like SLC and NREC to BlueZ, the record and socket
listening/connection handling logic could also be done in BlueZ side
so we use D-Bus to transfer the fd to oFono.
* What is the behavior of hsp when receiving CKPD=200?
This is what oFono does in BlueZ:
void telephony_key_press_req(void *telephony_device, const char *keys)
{
struct voice_call *active, *waiting;
int err;
DBG("telephony-ofono: got key press request for %s", keys);
waiting = find_vc_with_status(CALL_STATUS_INCOMING);
if (!waiting)
waiting = find_vc_with_status(CALL_STATUS_DIALING);
active = find_vc_with_status(CALL_STATUS_ACTIVE);
if (waiting)
err = answer_call(waiting);
else if (active)
err = release_call(active);
else
err = 0;
if (err < 0)
telephony_key_press_rsp(telephony_device,
CME_ERROR_AG_FAILURE);
else
telephony_key_press_rsp(telephony_device, CME_ERROR_NONE);
}
Next step will be to dial/hangup a call.
