Hi and thank you for your help.
I am using the latest firmware SYSKLi35.86A.0039.2016.0316.1747 and nothing change.
The version of the Bluetooth driver is 18.1.1551.2884 and it shows up in windows without any error.
It detects my Bluetooth devices (headsets/phone) and I can send/receive files and use my both headset only in HSP Mode (mono)
same problem on Ubuntu 15.10.
There is a newer Bluetooth driver. Please give a try and let me know the results.
