I’ve been using Ubuntu Mate for the RPi for the past serveral months, it’s absolutely amazing and it works great!!! (I recommend using an SSD for the root partition and an SD card for the boot partition).
I recently got an RPi3 and so I decided to upgrade from the 15.10.3 to the 16.04 development branch available. (I did do-release-upgrade -d)
After several hours (I think?) The upgrade finished and it booted normally and everything was great!
(I only saw the message about not upgrading the way I did it… and instead just re flash the image)
It then came time to test the bluetooth for the RPi3 but it didn’t work… (WiFi was fine!)
So I’m wondering the normal image, what is it that makes the Pi 3’s bluetooth work, what packages? Is it a special kernel image?
A normal bluetooh dongle works, but not the native one, it’s not detected AFAIK.
Any ideas on how to fix this??
I also upgrade my kernel via rpi-update, but the bluetooth would still not work.
Other than that, I"d say the upgrade to 16.04 went well for the pi!!
