The version of Bluez used in Alpine is not supported anymore.
Dear Alpine Linux Team,
No doubt, many of us have appreciated that you have included support for
Bluetooth, or Bluez in Alpine Linux.
As the version of Bluez used in Alpine is not supported anymore and new
version is recommended, we would like to kindly ask you to include Bluez
5 (5.9 at the moment) in Alpine Linux. It will improve Bluetooth
connection with many devices.
Thank you very much.
Sasha
