XPS 13 9315, Bluetooth issues

Before you do anything, contact your IT support staff to find out if they imaged the computer with their own image -- if they did and there's an issue with the way the drivers are installed, it may be the cause of the problem.

Yes same issues with my laptop 9315 and after raising issue they told me to do factory data reset but internally they dont have solution, even they dont know what to do

Small update: I do believe it's a driver issue caused by the image that has been initially put on the ssd, because I also have problems with the My Dell app: it starts, but after a few seconds the program disappears from the screen...

A factory install of windows wil occur soon I hope (for that I need to get my laptop to my employer abroad, which is not that easy...)

Having the same issue 2 different model types, Latitude 7440 and 5440, have done everything and have not been able to fix this issue. Bluetooth studently stops working at this moment if i turn off the Bluetooth toggle it gets greyed out and im not able to turn on again, i have to restart windows.

@AP10004​ Same here... When I switch to an alternate audio device (e.g. from bluetooth speaker to headset) the system sometimes plays no audio (and windows media player playbar stays on the same second). Only workaround for me is to temporarily change the audio device in the system tray to another device and back to the headset. That works for me for now (not handy though...)

I have the exact same problem with a XPS 9320 Plus, which seems to share the same Intel Killer AX211 chipset.

I've opened a support ticket with a detailed report, similar to yours. To me, this is a driver issue (or a bios one, perhaps).

Funny thing is, I got my laptop replaced (for a completely unrelated problem), and the problem is still there. So now, I can safely explain to Dell that, no, the issue is not an hardware one, but it's a driver problem.

It's a bit sad when your ultraportable laptop cannot run bluetooth properly. "T_T

Another test that I have performed, to complete your own report: I was asked by the dell support to try connecting my headset through USB. So I tried the jack-to-usb converter provided by dell. 

And the weird thing is, after a bluetooth crash (when you shutdown bluetooth capabilities and you cannot get them back up): my USB connected headphone couldn't get recognized anymore, whatever I did.

So I'm... not entirely sure that this is only related to bluetooth drivers. I wonder if this could be some kind of conflict between intel drivers and realtek ones for instance. Or something else. I really don't know what is going on.

I've got the same problems here on my Dell XPS 9320 : bluetooth impossible to turn on again after a turn off, when restarting after that, I have to "hard reboot" with the power button (resulting sometimes with a blue screen), need to manually switch from headset to speakers and back to get sound on the headset, etc...

I also uninstalled bluetooth devices (both in Bluetooth manager and Peripheral manager) but a reboot is needed as system is stucked in "Deletion in progress..." or the device keeps showing back..

It's been months with this problem and Support has not provide any useful help.

If someone has the solution to this problem, I would be very grateful if you share it here !

Thanks.

Yes, I've been experiencing the same issue, and I've reached out to more than six IT support team members. Despite one agent suggesting a motherboard replacement and even receiving a brand new laptop, I am still facing the same issue

@DELL- Nat M​ This is the Dell accepted solution....but has anyone with this problem actually gotten this "solution" to work?  And how exactly does an audio driver fix a bluetooth problem?

@NikonShooter24​ > I'm trying that solution for a few days now, and it does seem to work (still waiting a few more days to be sure).
About your question, I tested a Bluetooth USB dongle to replace the one from the laptop, and I still had numerous problems (see this other topic here: https://www.dell.com/community/en/conversations/xps/xps-9520-bluetooth-issues/64ef7c5840359957a93c184a?commentId=653a18a87af2d67a933c803e ).

I started to think that the problem didn't come from bluetooth after all, or maybe not entirely (there still might be BT problems on top of the Realtek ones, that is possible).

Just, take care: Dell Command Update apparently still proposes the Realtek Audio Driver from March, which seems to be the culprit (at least it did so for me this very morning). Pay attention to it while Dell updates its database, until this version goes away. >_>

@DELL-Nat M​ : i rolled back the driver on the 9315 as you suggested, and it seems to have fixed the problem: the Bluetooth tray icon does no longer 'freeze' when i toggle bluetooth on and off. I will further test this later with my headset(s), but it looks good now... Many thanks!

@DELL-Nat M​ It worked! Thank you!

I have had the same issue with my new XPS 13 and none of the Dell suggested solutions work. I should've returned the laptop instead of sending it in to Dell to be repaired, because now I've missed the return window and the repair didn't fix anything.
