Bluetooth Problems

[neihar956]

Had a new Liquid Series Desktop for a few weeks now but having problems connecting devices to Bluetooth using Windows 10.

The motherboard is a ASUS Z270E with built in Bluetooth which is turned on in the BIOS and Windows has all the latest updates.

The Bluetooth detects ALL devices I have tried:

- Bluetooth Soundbar
- Samsung Galaxy S5 & TAB S2
- Microsoft Wireless Controller

But when I click connect it says connecting for around 1 minute before giving the message - "Couldn't connect. Try connecting again."

I have tried all the Windows 10 Bluetooth fixes when searching Google. e.g. Turning Bluetooth and devices on and off, Uninstalling drivers and reinstalling etc ....

I originally thought it was a motherboard problem. So contacted ASUS where they said to update the drivers to the latest ... which I did but still the same problem. So I found an old Bluetooth dongle I had with my old PC and installed that but still the same problem.
Finally bought a brand new dongle and that arrived the other day. Installed that but the problem still persists.

Contacted PC Specialist Support and they advised in the first message:
"Have you installed the corresponding drivers for your bluetooth devices? If they are corrupted or not installed they will cause trouble connecting properly. "

To which I replied that these devices (Excluding the XBOX controller which I just received this morning) didn't need any drivers on my old Windows 7 PC.

Then I got a message back saying:
"Sorry to go down this avenue even still but can you confirm that you have installed this latest driver:
http://dlcdnet.asus.com/pub/ASUS/mb/02BT/BT_10.0.0.309_RS2_20170724.zip?_ga=2.251272064.723370526.1503997914-505988449.1502783132"

To which I have replied that yes I have installed the latest drivers.

So that's where I am at just now. Anyone any ideas what's going on?

Thanks.

As I understand things you've now tried three different Bluetooth adapters (the one on the mobo, the old one you found, and the new one you bought) and you have the same issue with all of them. Ergo it's not the adapter, and so it's unlikely to be the drivers for them either.

This could be Windows 10 and it would be worth doing some research to see whether this is a known issue with Windows 10.

It could also be radio spectrum interference, Bluetooth uses the 2.4GHz band used by WiFi and all sorts of home devices can cause interference. These range from florescent lights, microwave ovens, mobile landline phones, and I've even come across a faulty light switch that was interfering with WiFi. If you can try relocating the PC, move it some distance from where it is, ideally to a location other than your home.

Yes I tried 3 different adapters.

I see Windows 10 has many problems with Bluetooth but when I use the exact phrase in google using quotation marks .... "Couldn't connect. Try connecting again." ... I get 3 results. None which help.

Yes I have thought it could be interference but then why can I connect my Galaxy TAB S2 and Galaxy S5 to the soundbar and to each other while sitting at the PC? Those all connect by Bluetooth no problem its just the PC that can't connect to them.

When you say you've installed the latest drivers where did you source them?

ASUS Support supplied me with them. And PC Specialist gave me a link to the same drivers.

But that doesn't matter because I have also tried 2 different dongles. So its not the motherboard built-in Bluetooth.

That's a good question but without a solid answer. Radio is a funny old world and microwave radio (where Bluetooth and WiFi work) is funnier still. If you can move the PC (to another property if possible) and it still won't connect to a Bluetooth device then you will know it's not radio interference and can move on to something else.

In troubleshooting there is no truth that you cannot see. It doesn't sound like radio interference but the only way to eliminate it is to try the PC elsewhere.

Well took my PC down to my in-laws house .... Exact same problem. So definetly not interference.

That's actually excellent news, radio interference problems can be so hard to diagnose and rectify!

I would put my money on it being Windows 10 then. I know that's not much help but you might find something useful via Google or on the Microsoft site?

 

[neihar956]

Yes am sure its Windows 10 too .... but tried about every fix there is for Bluetooth and nothing help. Posted on the Microsoft Support forum so will see what happens.

Now to add to my problems I was playing Battlefield 1 and got the dreaded BSOD with the error: DRIVER OVERRAN STACK BUFFER

This Liquid Series from PC Specialist is turning into a bit of a nightmare. Especially since it was supposedly in testing for over a week.

Given that BSOD which is clearly driver related, and since I don't believe in coincidences, I'm tempted to suspect that it might still be a driver issue?

The best thing to try now would be a clean reinstall of Windows, allowing Windows Update to find all the drivers (or all the drivers it can) and see whether that's any better? You could (and probably should) take an image of your system drive now so that you can easily get back to where you are now if a reinstall doesn't fix it.

I don't work for PCS but I think that the testing phase is just to prove that the build works and that there are no cooling issues. It's not practical for PCS to test every single last feature I'm afraid...

When I check the BSOD dump using BlueScreenView it seems the driver which caused the BSOD is the Intel Gigabit Network Driver.

A clean reinstall was the one thing I wasn't wanting to do. Spent ages getting all the settings and installing all my software and games. It takes a long time even when you have the files for over 950 games for Steam on another HDD. lol. As Steam has to check all the files.

If you use a tool like Macrium Reflect (the free version) you can take an image of your system drive first. That way, if a clean reinstall doesn't fix the problem, you can easily get back to where you are now by restoring the image. With Macrium Reflect you can also mount a disk image as a virtual volume and access individual files and folders in the image, so you also have a good backup of the data on your system drive.
