We have fixed all reported Bluetooth issues and are almost ready with final release. There are some more features added.
Beyond Bluetooth issues we have added support for external GPS module. It can be used in Android Auto and allows to improve GPS signal and increase battery life of the phone.
Now there is also easy way to activate external Bluetooth dongle in case you need it, just type: sudo btswitch external command.
These are the last tests before final release.
