Not able to pair more than one BLE device in windows at same time

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.

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?
