I was confused by Rucio’s reference to “IKN”, but here is how I got both controllers to work in 1909. I’m assuming he meant “IRK”. Heads up, this will mess with your computer’s registry and has the potential to break windows if done incorrectly. No one except yourself is responsible for anything that may go wrong.
* Connect one of the Gear VR controllers to Windows via the Bluetooth menu. Make a note of what the device name is, specifically the 4 letters and numbers inside the parenthesis. This should work without error.
* Regedit.exe as Administrator, navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Keys. On the left, there will be a subkey (folder) under “Keys”, the name of this folder will be specific to each computer. Expand that folder with the downwards arrow. Now you should see a folder with the last 4 characters in the name matching the 4 characters in the Bluetooth menu. Open this folder.
* There is a entry with the name “IRK”. Click that and you’ll see the the attached screen. Replace the 01 at the start of each line with 02.
* Close out of Regedit and restart your computer.
You should now be able to pair the second controller without issues. You don’t need to worry about changing that value back, but you may need to remove both devices and repeat this process if you ever need to repair the controller.
