Bluetooth keeps disconnecting and reconnecting once in a while

Hi,

on my 13" MacBook Pro 2019 all of the bluetooth devices, such as mouse, keyboard, bluetooth speaker or AirPods, when connected for a while, disconnect for about 30 seconds and it reconnect after that. I wonder whether it is Catalina problem (I have latest public release), or if it could be a hardware problem, when it is getting warmer or so?

It is annoying, for example when I have online meeting and the AirPods disconnect, I do not hear anything for 10 seconds before it switches the audio to MacBook speakers, then I hear 10 seconds audio via the speakers, then the AirPods are reconnecting again and I hear nothing for another 10 seconds. After that the AirPods works fine. This happens every once in a while, maybe once per hour or once per two hours of working on the laptop. The same is happening with all the bluetooth devices at the same time, so while I am not hearing anything, my mouse does not work and my keyboard does not work as well. I still can use touchpad and the MBP keyboard, but it is really annoying to switch for 30 sec or so.

Any help or advice on that?

Thanks!

Hey!

Thanks, it seems like this article helped. Looks like removing potentially corrupted files was the solution. I did reset the bluetooth module as well just because I could. I will put the steps, more details is on the link that larakueski sent.

Remove potentially corrupted files

Step 1: Open Finder on your Mac and click on the “Go” menu in Menu Bar, then click on “Go to Folder…”

Step 2: In the Go to Folder window that opens up, type in or paste /Library/Preferences and then click on the blue “Go” button.

Step 3: In the new Finder window that opens, locate the com.apple.Bluetooth.plist file, right click on it, and select “Move to Trash.”

Step 4: Open the “Go” menu in the Menu Bar once again, and just like before, click on the “Go to Folder” option again.

Step 5: In the Go to Folder window, delete any text in the text field and type in or paste ~/Library/Preferences/ByHost into the text field and click on the blue “Go” button.

Step 6: When the Finder window opens, locate the com.apple.Bluetooth.xxxxxxxxxxxxxxxxxxfile, right click on it, and select “Move to Trash.”

Note: This file starts with com.apple.Bluetooth, and the rest of the file will have a random mix of numbers and letters, which is different for everybody. Don’t worry if the seemingly endless list of files looks intimidating – there’s should only be one com.apple.Bluetooth file here, so just find it and delete it.

Step 7: Now reboot your Mac and your operating system will automatically generate new Bluetooth files when you turn Bluetooth off and on again.

Reset your Mac’s Bluetooth Module

Step 1: Hold down the Shift (⇧) key and the Option key and click on the Bluetooth menu in your Menu Bar on your Mac.

Step 2: Go to Debug > Remove all devices and click on it to disconnect from all paired Bluetooth devices.

Step 3: Now open the same menu once again and click on Debug > Reset the Bluetooth module to reset your Mac’s Bluetooth module.

Step 4: After resetting your Mac’s Bluetooth module, you can now attempt to re-pair all of your Bluetooth accessories and everything should work as expected.

Thanks!
