NUC6i5SYK - Bluetooth AD2P stop working on both ubuntu & windows 10 even in a LiveCD. Weird HW bug

Hello,

I got a strange bug with my NUC6i5SYK, my bluetooth headset stop working in ad2p mode (stereo mode). but still working in hand free mode.

It sounds like a software problem or headset but no. I disabled the build-in bluetooth then add a bluetooth dongle then windows & ubuntu are working again with AD2P.

the headset is detected and visible by windows/ubuntu but no sound. just from time to time a big buzz.

btw the wifi keeps disconnect randomly. The signal is strong and my phone is on the same wifi works with no problem. So I gotta use Ethernet

My BIOS has been updated to the latest one and I use the default settings.

it is a known bug or is a hardware failure ? Please help me !

my configuration :

NUC6i5SYK

Samsung 850 EVO

SSD scandisk

2x8G HyperX

Hi NUCOwner,

Could you please run our tool Intel® System Support Utility and send me the results?

The latest BIOS version 0039 solves the random issues with the Bluetooth and WIFI.

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.

Hi,

Still not working with this version (18.1.1611.3223).

Btw the problem is the same under ubuntu. So a driver under windows wil not help much.

Hi NUCOwner,

Could you please let me know how you are setting this option in the NUC?

Please send me the brand name and model of your third party Bluetooth device.
