For people having problem with bluetooth, you should try (tested on
kernel 4.4) the following method :

Here is a copy/paste :

You need to apply this patch :

and to do so you can run these commands :

sudo service bluetooth stop
sudo apt-get install build-essential linux-headers-$(uname -r)
cd to your prefered build dir
apt-get source linux-image-$(uname -r)
sudo apt-get build-dep linux-image-$(uname -r)
cd to the created source dir
cp "/boot/config-$(uname -r)" .config
cp "/usr/src/linux-headers-$(uname -r)/Module.symvers" .
edit drivers/bluetooth/btusb.c and apply the patch manually
make prepare
make modules_prepare
make M=scripts/mod
make modules_prepare
make M=drivers/bluetooth/ modules
sudo cp drivers/bluetooth/btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth
sudo service bluetooth start

Enjoy !


For Wifi, I have some trouble with wifi that crash sometimes, and I need to restart network manager. Depending on the network it can happened every 10 seconds or every 4 hours. I tried the branch 2.0.3a-1 which solved some problems, but not all. If someone manage to solve this problem please tell me ! Here is the Issue and some logs : https://github.com/neurobin/MT7630E/issues/18

Bug description:
  This device is appearing in some OEM machines, but driver is not yet
  available in mainline.

  The driver seems to be present in machines with pre-installed OS, but
  isn't available on the download-and-install versions!

  The driver that upstream is working on can be found at
  https://github.com/lwfinger/mt7630.
