Thought that Apple had solved their bluetooth mouse problems. Didn't have any problems with Big Sur or the Beta's of Monterey, and now with Monterey RC1, macOS 12.0.1, they seem to be back. When I wake my M1-based mac mini up after sleep, sometimes the bluetooth mouse doesn't reconnect. It's a hassle removing the mouse and re-pairing it, since I walk away from my computer a lot during the day. The worst example was yesterday, when it would not reconnect, and asked me for a code that's supposed to be on the mouse or in the manufacturers guide for the mouse....no code anywhere, of course, so I finally turned the mouse off and then back on, and turned on pairing mode. Finally reconnected when I did that. Usually it's easier, but it is annoying none the less.

Wondering if I'm alone with this one, just unlucky, or if others have experienced it? I reported it to Apple, we'll see if that brings anything. But wondering if I need to go back to the external bluetooth dongle to get around this one, or if anyone else has experienced this, and perhaps has a work-around?

The other problem I'm having relates to printer scaling, but that's most likely an Epson software problem that Epson will have to deal with. This problem also is new to 12.0.1, wasn't in the Monterey Beta builds.
 
not sure about Monterey but you can try to execute

sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport

and then a few seconds later:

sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport

from a terminal window.
 
Thanks, not sure that this worked...The unload didn't work, got an error message the kext couldn't be unloaded. So I turned off bluetooth, restarted my system, and it still said that it couldn't unload the kext module. The load following that didn't produce any error, but I don't really know if it did anything.

We'll see, I guess, but given that the kext wasn't unloaded, I don't know if it would load it again or not, or what the result of that will be *smile*. My bluetooth mouse has continued working, so that's a good sign, anyways.
