Let’s start with the basics. Many times the most basic steps like restarting your Mac can fix a Bluetooth connectivity issue.

You can restart your Mac from the Apple menu> Restart. It will fix almost any bluetooth issue, especially the one where the bluetooth module crashed.

You should also remove all USB devices from the Mac and try your luck with the Bluetooth connection.

2. Reconnect the Bluetooth device

If your device isn’t connected to your Mac, turn off your Bluetooth device, then turn it back on to see if it reconnects. This is also a good time to check the battery level of your device. If it doesn’t have enough power, put it on charge.

If your device does not reconnect, you can restart the Bluetooth radio on your Mac. To do this, click on the Launchpad icon in the Dock and head to System Preferences> Bluetooth.

Step 4: Your Mac is now in Safe Mode. Test your Bluetooth now. Does it work?

Step 5: In either case (running or not), restart your Mac normally. This will exit safe mode. This means restart your Mac but don’t press and hold any keys.

Step 6: When your Mac is on, test Bluetooth again.

6. Delete registered Bluetooth devices

If turning off and on your Mac doesn’t work, turn your Bluetooth devices off and on again.

There is another reason to delete devices: If you are signed in to too many devices, it can cause connection issues. While seven is the maximum number of Bluetooth devices, you may run into issues once you go over three or four, as some devices need more data than others.

Step 1: Open System Preferences> Bluetooth.

2nd step: Click the x button next to each device and clear the list of Bluetooth devices.

Remove devices

Step 3: Try to connect the bluetooth device again and see if it works or not.

7. Update macOS

I started noticing Bluetooth disconnection issues on my MacBook Air when I updated my device to the latest macOS Big Sur update. Apple is generally quick to fix these issues with future updates. If you are in the same boat as me, you must download the latest patch available in the System Preferences menu and install it on the device.
