Windows 10: problem adding second pair of bluetooth earphone of same make/model

Hi


I had a pair of Sennheiser CX 400BT TW earphones which worked ok with windows 10 bluetooth, i did need to turn the bluetooth on/off in a particular sequence to get them connected. However, then i lost them, and bought a second pair. Ever since then i haven't been able to connect them to windows 10 bluetooth. I'm quite sure the problem is that windows has a record of the old pair, old mac address etc and when i add these it assumes it's the old pair and can't connect. I will be able to add them but when i try to connect it just says "That didn't work. Make sure your Bluetooth device is still discoverable, then try again.". The problem is not that simple.



I went through the registry and found numerous entries for CX 400BT TW e.g.



Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\UFH\SHC

value name = 66

C:\Users\XXXXX\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Bluetooth\LE-CX 400BT TW.lnk
C:\Program Files\WIDCOMM\Bluetooth Software\BTWUIExt.exe
/deviceAddr=001b66cf704a


from there there are many instances of device address 001b66cf704a


Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\DeviceClasses\{00001800-0000-1000-8000-00805f9b34fb}\##?#BTHLEDevice#{00001800-0000-1000-8000-00805f9b34fb}_001b66cf704a#9&1c2175c8&2&0005#{00001800-0000-1000-8000-00805f9b34fb}


DeviceInstance: ........



Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\DeviceContainers\{a7692064-684f-5e85-8b6f-7d882a327923}\BaseContainers\{a7692064-684f-5e85-8b6f-7d882a327923}





These last entries i can't delete. Is there a way i can delete all these entries? start in safe mode without bluetooth service?


At the moment the only thing i can think is to completely reinstall windows which seems like the nuclear option.

Any help? It's a real pain not to be able to use these during lockdown.


thanks

Bluetooth does not Recognize/Pair/See Bluetooth Hardware


System Information: Asus Notebook UX303L, Windows 10, Microsoft Arc Touch Mouse Surface Edition

Okay, I've been working on this for awhile and have tried a million things. I'm going back to square one so pretend I haven't tried anything yet.

Here is the problem.

I just upgraded to Windows 10 (from windows 8.1) on a 2 month old laptop. On previous version there were NO problems with bluetooth. The problems started immediately after upgrade.

When the upgrade finished Windows 10 remembered all of my previous Bluetooth pairs. My bluetooth mouse (Microsoft Arc Touch Mouse Surface Edition) worked before the installation but after my system reboot the cursor no longer showed movement. The batteries are new. The mouse is acting exactly like it does when it is properly connected (lights flash, makes scrolling sounds, etc). When I checked the Bluetooth device screen it still showed as paired. I rebooted. No change. So I unpaired the device. When I unpaired the device it flashed for a second as a possible device to pair with and then was no longer on the list. Other possible devices to pair with appear and disappear from the list without cause. (Ex. sees a scanner for a few seconds then no longer has a scanner. Sometimes its up for a few minutes at most but the list is constantly flickering.) So I rebooted. Then it did not see the mouse at all. I did this for several days. Sometimes when I would turn on my laptop it would flicker, sometimes it would not. After about 3 days with no explanation it suddenly showed up and did not flicker. I connected the mouse and it worked for about 2 days. On the 3rd day I tried again, and the cursor would no longer respond even though the mouse was acting exactly the same. I rebooted. No change. I unpaired the device and it never showed up on the list. It's flickered a few times but when I click on it to pair it pops up with an error basically saying "cannot pair. Please check and see if the device is still set to connect to bluetooth." That is only on the rare occasion that it actually shows up on the list long enough to hit pair (maybe 2 times out of 50 attempts or more.)

I've tried everything I can think of, but I'd like to try everything in order that someone else would try to see if I'm missing something.

It is a Microsoft mouse by all means it should work on Microsoft drivers. :/ Arg. Please give any suggestions to help.

 

Cannot use bluetooth device

Cannot use bluetooth device

1 Pairing is done in Settings, Devices
1.1 You click on Add Bluetooth or other device
1.2 You choose Bluetooth
1.3 If there is a pairing button on the bluetooth device itself then you press that now. You need to check the instructions for your bluetooth device to see how to do this - several automatically go into pairing mode when they switch on, others have a button that needs to be pressed for, say, 5 seconds.
1.4 The computer detects all available bluetooth devices and you select yours from the list. If yours is not on the list then Windows could not detect it.
1.5 It connects - pairing includes connecting
1.6 The computer sounds a buzz in the earpiece then displays Your device is ready to go and you click on Done
1.7 The device is shown in the devices list below the subheading Audio and it shows it as connected
1.8 The device should also appear in Control panel, Sounds, Playback tab
1.9 The device should also appear in Control panel, Devices & printers
1.10 {I just paired some bluetooth earphones as I typed so I could make sure these notes were correct} You use a music player and the sound comes out of the bluetooth earphones

2 If this is not happening for you then go to Contol panel, Devices & printers
2.1 Right-click on the device & select Remove device
2.2 You can now try pairing from scratch again
2.3 Several other users have reported that only removing the device with Bluetooth command line tools - BluetoothInstaller allowed them to re-pair again [see xzion's guidance below]
2.4 Yet others reported that only the KeithM code or Bungee's guidance worked for them [see below]

3 Where is this all going wrong for you?
[I assume we are definitely talking about bluetooth headphones/earphones. I understand that WiFi ones do also exist.]

Several people registered in TenForums just to be able to thanks xzion, KeithM & Bungee. Apparently, what worked for some people did not work for others so each solution seems worth trying.
