Install and update the latest BIOS & video card drivers, once done, use the below steps:
Open the controller's battery cover.
Press and hold the pairing button. It is located below the batteries.
Press and hold the Windows button for five seconds.
Release both buttons simultaneously. The process of resetting should take about 15 seconds.
Pair your motion controllers with your PC.
Once done, try the below steps:
Open the Mixed Reality Portal app on your PC.
In the side menu click on see more.
Select set up controllers.
In the settings screen you now see, click add Bluetooth or other device.
Open the battery door on your controllers.
Press the small button below the batteries for 2 seconds until the lights flash.
When the controllers appear in the list, click connect.
Now, put on your headset and make sure that they're working and tracking OK. If you don't see them as in the image above, hold down the Windows button for two seconds until it vibrates to turn them off.
Then repeat the process to turn them back on again and this should make them both appear in front of you.
Once the controllers have paired over Bluetooth the lights on the ring will stop flashing and instead stay bright and steady.
Hope this helps! Keep me posted.
