MacBook Airs cannot discover Bluetooth radio

Is the radio unpaired from anything else, and set to discoverable mode per its own instructions?

Sounds likes its already aired to the iPhone, so won't appear for anything else until its unpaired from that and in discoverable mode again.

❝If you are seeing your Model One BT appear on your Bluetooth list but are having trouble connecting, try forgetting your Model One BT in the Bluetooth menu of your device and then re-pairing them. If that does not resolve the issue, please contact Customer Support for further assistance*.❞

You might start with a freshly booted MacBook.

If that doesn't work, try making the Bluetooth connection while booted in safe mode.

Safe mode will often correct weird software behavior by forcing the OS to clear caches, do disk repair and other self-maintenance and housekeeping and temporarily disables third-party mods.

How to use safe mode on your Mac - Apple Support 

Can you pair the device while in safe mode?

You can exit safe mode by restarting your Mac normally, then reevaluate the problem.
