Mac OS Catalina keeps disconnecting bluetooth devices

Hi, I am using MacBook Pro Late 2016 model and Mac OS Catalin 10.15.2.

After the update to Mac OS Catalina, my bluetooth devices - Bose speakers, headphones, mouse keep disconnecting randomly. Even if they are connected, Mac OS is not able to find their audio output and delivers a very low sound.

As per few articles on the Internet, I have tried deleting the /Library/Preferences/com.apple.Bluetooth.plist and resetting PRAM but nothing helped. Please provide a reliable and valid solution for this issue.

PS: I have tested my bluetooth devices with other laptops / phone and they work perfectly fine.

Thanks!

MacBook Pro 13", macOS 10.15

I was having the same problem, until I read a solution related to delete the Bluetooth plist entry. Did that, and Bluetooth didn't work anymore. Until last night. I watched a video on Youtube and the solution shown didn't work, but I figured it out by myself.

Go to the following page...https://developer.apple.com/download/more/
Search "Additional Tools"
Download version 11.4, and install
Open "Hardware" folder, and execute Bluetooth Explorer. A Bluetooth icon is shown on Apps Bar. Click there to open the App.
Under the "Tools" menu select "Modify Software & Device Configuration
On the "Setup (Auto BTSA)" square, click on "Go". The computer will restart, and Bluetooth will be Active again, and no more disconnecting problems.

Reinstalling OS does not help! I clean my iMac and install it on a crean drive from Internet Recovery. Did not restore from Time Machine backup, just clean install!

Since Apple keep ignoring our requests, I bought this Bluetooth on amazon https://www.amazon.ca/dp/B00ITYBN6E/ref=cm_sw_em_r_mt_dp_U_GEEbFb528NK12

I don't have any issues now :)

No. They didn't fixed. Apparently they keep ignoring their customers and don't care so much about it.

Thank you Calvin! Looks like most have done steps 1 - 6 there. Wondering if the magic sauce is in step 7 and 8. Can anyone else confirm which step seemed to resolve?
