Fix Bluetooth LE devices not pairing/connecting in Windows 10 Creators Update

The popular Bluetooth technology can wirelessly transfer data between two devices, such as your PC, smartphone, a speaker, mouse and keyboard. I was able to pair my Altec Lansing MZX300 headphones in Windows 10 on my Surface Pro 4 tablet, but it just becomes not connecting after Creators Update. The device stays in discoverable mode, and I click on Connect option in the Action Center and nothing happens. Then I test it with my Android phone and it is normal. How can I resolve the problem?

If two devices fail to be pairing in Windows 10, go to check if you have already turned Bluetooth on in the Settings app. Another method is to do a soft resetting by powering the device off and back on. In Creators Update, some older Bluetooth models seem to be not compatible or the installed driver is out-of-date, and you could try the tips to troubleshoot that.

* A recent Windows update has fixed the Bluetooth LE device connection issues with Broadcom radios.
