Bluetooth: Fixed issues
Fixed a bug that prevented the Digital Car Key app from performing low-latency scans when running in the foreground.
A fix has been implemented to use custom UUIDs instead of standard UUIDs for the HOGP service in the Android header tracking service.
The head tracking codec capabilities are used to detect transport support in the LE audio stack.
A fix has been implemented to prevent Bluetooth pairing requests from being immediately rejected when there is a mismatch between the transport suggested by the API and the transport observed by the Bluetooth group, which may improve pairing success rates.
