- Add back service - Add HID attributes - Add key attributes - Add sepolicy - Associate the script w/ the bluetooth group to avoid DAC overrides * Sadly there is no clean way to have a vendor HAL accessing mnt_vendor_file to write to bluetooth configs @ /data/misc w/o triggering neverallows. * Not gonna enable neverallows for for this, so just making the domain permissive until/if someone cares. * Note: MAYBE a vendor HAL could read it from mnt_vendor_file and expose it to a system_ext app, which then could use the undocumented auto-pairing API to do this, but man, IDC.
