Bluetooth mouse connection issues on macOS 11.1 on 2017 MBP 15"

I'm having a strange bluetooth problem and I think it all started after upgrading to BigSur 11.1.

I get bluetooth devices with random names connecting to my laptop. Once one of those gets connected, my Logitech MX Master 3 no longer works. I have to go to bluetooth properties and repeatedly disconnect those to make the mouse work again. Every few minutes this thing repeats and it becomes very annoying. Those names are random and look like MAC addresses.

It's curious that they only interfere with the MX3 and not with the Apple bluetooth trackpad or AirPods Pro or other bluetooth devices. I tried removing the MX 3 from the bluetooth devising and pairing it again but it doesn't help. What to do? It happens so often that it makes my mouse unusable.

I forgot to mention, this is on a 2017 MacBook Pro 15" Touch Bar notebook.

I am also experiencing the same issue on my 2019 15-inch MacBook Pro with Touch Bar, which started just recently.

I have a Logictech MX Ergo, and have been having dozens of Bluetooth disconnects each day. Every time this happens, a random Mac address shows up in my Bluetooth list as a paired device. The random device disconnects after about 30 seconds and the mouse starts working again. It cycles through this list or a new random device intermittently appears.

No fix for this yet? This is getting very annoying!

Yes, BT is set to discoverable, but I could not find a way to turn that off ...

I wonder if there is a terminal command which allows the Mac to deny all bt requests.

It looks like 11.2 fixed it for me, although not from start. After upgrading to 11.2 I was still having the same issue for a couple of days more and then it misteriously went away. Upgraded to 11.2.1 yesterday and it's still ok. Fingers crossed!
