However that wouldn't work with our implementation playing the role of
the audio gateway strictly requires a modem with voice call
capabilities.. no way to inject your VoIP stack here. It also hardly
depends on how the hardware is build. For HFP on most Android devices
the audio is directly routed from the microphone to the BT chip without
involving the CPU so we can gurantee you're even able to inject your
VoIP audio data.
You mean you can't use Skype with a BT headset? Sounds like we'll get
flack over that.
That depends. We're bound to the audio routing capabilities we get with
the Android HAL implementation. Also lets differentiate HFP and HSP
here. The HFP implementation is meant for voice call capabilities with a
modem and that is how we deal with it at the moment. The other thing is
HSP which is just meant for headsets without voice call control
capabilities. With HSP we should be able to set things up that you can
use it for Skype or whatever VoIP system you want. However we still need
to figure how that is possible with the Android audio HAL.
My only point is this: since I believe we should have a generic
mechanism for reading the per-device and user-overridable bits of that
file, I see no reason for implementing special exceptions for this use
case to *prevent* the user changing it.
We will only read whatever file this has in only once for Bluetooth on
start and then take with what we were configured for. If that changes
across restarts of the service then it does. However I still see only
corner cases where this is required to be adjusted by the user for
Bluetooth. It should for sure be nothing which is changeable in the
settings app for a normal user as he wouldn’t really know what he is
dealing with ..
