* Fix of the issue that incoming call triggered
handsfree ringing which didn't stop after
calling side hung up.
* Cleanup of several places in code, minor
bluetooth <-> cellular integration refactor.
Fix of the issue that after connecting
to Bluetooth device it was impossible
to disconnect using Disconnect button.
Refactor of connect/disconnect events
naming (and all names related).
Now, both profiles can operate separately. Additonally, minor
fixes has been applied to allow calling via car audio system.
Some infotainment systems still don't work though.
To be able to pair properly using SSP the BT device have to know
which services we're running, thus we need to register SDP entries
after startup of the BT stack
Reworked AppSettings handling of BT devices to be prepared for
handling the HFP profile, eliminating by the way few bugs and
speeding up the flow (by getting rid of few refreshes).
Added unit tests for handling the BT devices flow
Due to wrong logic, all devices were disconnecing during unparing
Now, the disconnecting is performed only when the unpaired devices
is the connected one
Added HSP ring sound on incoming call event while
there's bluetooth connection active and HSP is
selected as the current profile.
Possibility of pick up/decline the call using
BT device buttons added.
Slightly changed HSP initialization according
to the UML-s added.
Changed call hangup handler in service cellular.
This PR:
* provides Bluetooth-Harness API messages definition [EGD-5944]
* provides Bluetooth-Harness API messages implementation
* provides Bluetooth-Harness API usage on harness side [EGD-5946]
* provides Bluetooth-Harness tests [EGD-5947]
Due to incorrect stopping the BT scan, re-enabling it caused
failure to HCI state machine, which was indirect cause of failing
connections. Now it works
To be able to connect to the BT device with more than one audio
profile, we need something to manage those profiles. Created here
ProfileManager made it convenient
To be able to work properly with BT, CPU freq has to be at least
at Level_5 - to be fixed!
