The built in drivers from Ubuntu 12 and Ubuntu 14 are not able to support bluetooth functionality of my RTL8723BE chip. I used to install the drivers from this two unofficial repos:
https://github.com/lwfinger/rtlwifi_new
https://github.com/troy-tan/driver_store/raw/master/bluetooth/8723BE/
Those drivers temporary make bt work but very unstable and they are overwritten with Ubuntu updates - so this is not a solution to reinstall unstable drivers day by day.
Is there a way to get this BT chip work stable and consistant in ubuntu 14, the same way as under windows?
