I've been using bluez, ofono and pulseaudio for bluetooth audio tests for a
few months. While everything worked fine with bluez 4, I've the need to
include BLE tests which require bluez 5.
This leads to quite some changes regarding HSP and HFP. My main requirement
is to test a bluetooth headset. Using pulseaudio with its native HSP
support I can have audio both ways from and to my headset. As I would like
to include the telephony features, I'm trying to move to ofono and HFP.
I've not found the current status of ofono and its HFP support. What use
cases are currently supported (audio gateway and/or headset) ? I tried to
configure pulseaudio to use ofono as HFP agent but I keep receiving the
following message when switch from A2DH to HFP : "Refused to switch profile
to headset_head_unit: Not connected"
Is there any limitation or am I missing something ?
