Windows 10: More than one bluetooth LE device cannot be paired on Windows 10

Hi there,I try pair one ble device , it is not problem.When i try pair second ble device ,gives a Windows error "Try connecting your device again".It is possible to pair the second device if the first is removed, but never two at the same time.The issue with the second device happens whether the first device is still connected or not. If the first device is in the paired devices list, the second cannot be paired.What is the cause and solution?Thanks for help.

Bug in windows bluetooth le GetGattServicesAsync method

The problem description:
Sometimes it is not possible to get some response from the method GetGattServicesAsync with the parameter BluetoothCacheMode.Cached or BluetoothCacheMode.Uncached. Only the windows restart helps to reconnect the le device and to get the services from the le device.

We use Windows.Devices.Bluetooth.dll with .Net Framework 4.6.1 to build the class library.
The Windows PC shall connect the Bluetooth le device.

Steps for the problem reproducing:

1. Discovery the devices with the determined service
   
2. Call the method FromBluetoothAddressAsync with the Bluetooth address of LE device
   
3. BluetoothLEDevice is found
   
4. Pair the LE device with desktop:
   
   
5. Check the connection status. If the status connected, call the method GetGattServicesAsync(BluetoothCacheMode.Cached)
   
6. Sometimes is not possible to get the response from GetGattServicesAsync. After 30 seconds we cancel the task, dispone BluetoothLEDevice, unpair and try to reconnect le device. The reconnection is failed and only the Windows restart helps to establish the connection to the le device.
   

PC:

Pairing bluetooth LE smartband failed

Hi Jesinta,

I write you information which you requested:

1) When I try to pair with smartband the result info on screen is "Couldn't connect"

2) Device information from my Mobile Phone:

Windows 10 mobile build is 10.0.10572.0

Firmware revision number: 02177.00000.15184.36003

Radio software version is 401c3.00009.0001

Aditional info:

When I had paired smartband in Windows Phone 8.1 and I upgraded to Windows 10 insider preview the paired device is listed in bluetooth settings and I can connect to it, but when I remove the paired device and try to pair it again in Windows 10 isider preview
I get the error "Couldn't connect".

My notebook where I have Intel(R) Centrino(R) Wireless-N 2230 card with Bluetooth LE and Windows 10 OS I could pair with smartband too.

Regards,

.

 

Bluetooth Devices will not Pair


Hi,

Hopefully this is the correct Forum !

I have a Microsoft Mouse 5000 and Wedge keyboard (the early one that does not fold).
Both have been working perfectly.

Recently I paired them both successfully with a new Samsung tablet, but when I came to use them again on my laptop,
I found that I could not pair either of them.

I have spent countless hours researching this without success.

Here's where I am now:

Settings > Bluetooth & other devices does not list either of them.
Device Manager > Bluetooth has both of them showing and reports both working properly.

Device Manager reports as follows:

Notebook Mouse 5000:
No driver files are required or have been loaded
The Events tab says that further installation is required

Wedge Mobile Keyboard:
No driver files are required or have been loaded
The Events tab says that further installation is required

The 2 Service Discovery Service entries also report that further installation is required.

Can anyone suggest the way forward, please ?

Regards.
