Windows 10: Repeat Bluetooth Pairing Request

I paired my phone to my PC by Bluetooth so I could use the calling feature but every 5 or 10 sec it unpairs my phone and ask me to repair by confirming the codes. How do I stop this from happening I tried removing the phone from my pc and completely disconnecting it from Bluetooth but the same issue keeps happening.

Bluetooth Stopped pairing

On Monday my wireless headphones were working ok, on Tuesday they weren't . When I switch them on now, I still get the 'connected' message, but they no longer show up in the list of connected devices. I've tried uninstalling and re-installing the Bluetooth adapter, re-installing the drivers, rolling back the drivers etc, and although i get the 'connected' and 'pairing' messages, they still don't appear on the list and are not working. Any suggestions, please? (There may have been an update installed on Monday night?) Windows 10 Pro. version 22H2. Build 19045.3930

 

Windows 10 Enterprise- New Bluetooth Pairing is requested when logging into Windows even though pairing has already been completed on iPhone.

iPhone With Windows 10 Enterprise Via Bluetooth

Bluetooth pairing is requested when logging into Windows even though pairing has already been completed. After that, even if the pairing is done, pairing will be asked again at the next login to Windows every time when the Windows is restarted.



Our iOS app acts as a Bluetooth central and the other as a peripheral (Bluetooth Driver on Windows).

when the app is trying to connect using Bluetooth Low Energy (GATT) at step 5 as mentioned below, new pairing is requested from windows every time when the PC is restarted.



Steps to reproduce the problem:

• S1: log into Windows and connect the app to the Windows computer
  
• S2: See the paring request on Windows and on iPhone,
  
• S3: Pair on both Windows and iPhone
  
• S4: Turn off the Bluetooth toggle on iPhone and then turn it on
  
• S5: Restart windows and see the login screen
  
• S6: Start the app on your iPhone and try to connect,
  
• S7: See the paring request on iPhone
  
• 
  

With the above steps, if this issue is not reproducible, try rebooting the iPhone instead of changing the Bluetooth toggle at S4.



we also observe the iPhone device is receiving this log from Windows:

We observed that looks like the issue reproduces more consistently when the windows restarts or reboots.



On the pairing request alert dialogue on iPhone, If I press "cancel", the app disconnects from the peripheral (Windows). If I press "pair", the peripheral nothing happens. However, Windows continues sending me pairing requests whenever the machine is restarted or rebooted.

We did not observe this behaviour with the Android Device. Windows and Android work without any problem (i.e. No new Pairing is requested once the device is paired in any situation).

In the below screenshots, we could see that the iPhone is already paired in Windows Bluetooth Settings but the Paring is requested from Windows on iPhone to pair again and in the background, our app is successfully connected to Windows using Bluetooth Low Energy (GATT).

1. Is this a known bug with Windows 10 Enterprise?
   
2. Is there any way to get around this issue?
   

Sample Code to reproduce the problem on iOS:



Our iOS app acts as a Bluetooth central and the other as a peripheral (Bluetooth Driver on Windows)

1. Initializes the central manager with a specified delegate and dispatch queueself.cbManager = [[CBCentralManager alloc] initWithDelegate:self queue:bleManagerQueue];
   
   
2. Scans for peripherals that are advertising services to discover other Bluetooth devices, passing in the UUID of the service it’s searching for.
   
   [self.cbManager scanForPeripheralsWithServicesNSArray<CBUUID *> *)serviceUUIDs optionsNSDictionary<NSString *,id> *)options;]];
   
3. When the central manager discovers a peripheral with a matching service UUID, The method saves the peripheral as the property discoveredPeripheral and calls connect to it.[self.cbManager connectPeripheral:[[self.currentConnection device] peripheral] options:nil];
   

Step 3, when trying to establish a connection to a peripheral, pairing is requested even though pairing has already been completed. After that, even if the pairing is done, pairing will be asked again at the next logon to Windows.

Is this a known bug with Windows 10 Enterprise?

Is there any way to get around this issue?

 

Bluetooth Stopped pairing

1 If your headphones are also paired with other devices then un-pair from those others even if the device claims to be able to cope with multiple pairings. Then proceed to step 2 and/or 3. 2 Try going to Control panel, Devices & printers then selecting & deleting the device in order to then re-pair. That has worked me me several times. 3 If that does not work then unpair using Bluetooth command line tools xzions link to Bluetooth command line tools - TenForums in order to then re-pair. As you'll see in that thread, many people have raved about how effective these tools are. - When I've been forced to use them I've taken the simple option of un-pairing & then re-pairing all my Bluetooth devices Code:

- As you'll see in their instructions, you can use them to remove individual devices instead e.g. Code:

but I've never tried that. Others have, see Remove just one Bluetooth device - DrNefario #83 - TenForums Best of luck, Denis
