I did the same patch - modify firmware patch and speed initialization patch... and I got bluetooth working on RPi! I used my own app to test it - https://github.com/Nikolay-Kha/BluetoothAudio hcitool scan also works fine. bluetoothctl starts, but I cannot type anything there, don't know why.
Patch, that I did for bluez 5.37 is in the attachment, prebuilt hciattach is also there. I took and install firmware from here - wget https://archive.raspberrypi.org/debian/pool/main/b/bluez-firmware/^Cuez-firmware_1.2-3+rpi1_all.deb to start bluetooth I used this commands(script in the attachment also): sudo ~/bluez/tools/hciattach /dev/ttyAMA0 bcm43xx 921600 noflow - sudo ~/bluez/tools/hciconfig hci0 up But, there is always BUT... I experience very weak signal. My bluetooth headset which works normally with 5 meter distance with my phone, doesn't even connect to board with 1 meter. It works only when I put headset right on board. Probably it's just a hardware issue of my RPi board instance... or some system setting, I don't know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1674509 Title: Unable to find bluetooth device on RPi3 running Ubuntu Core 16 To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1674509/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
