bamjus good to hear 🙂 - you are close!
You are pressing the 'Scan' button in slr interactive app while keon is blinking blue?
Make sure quest 2 and Keon are very close to eachother (no obstruction)
You are positive SLR Interactive has all permissions on allowed by Quest 2 and Bluetooth is enabled?
If unsure, just uninstall SLR Interactive, reinstall again to make sure
Doesnt hurt to then reboot your devices (Keon and Quest 2) just in case as well
If still unlucky - search for Keon on your phone bluetooth (but do not pair) to ensure its actually working in pairing mode
