Appoliogies if ths has been posted. I did a search and couldn't locate this exact issue. I'm very new to Linux so any help is greatly appreciated.
I have an iMac18,3, with a Broadcom Corp. Bluetooth USB Host Controller. It looks like the chipset is BCM20703A2.
Whille bluetooth appears to be active, it often seems to have trouble connecting. When connecting to my Xbox One contoller, it will sometimes go into a cycle of quickly connecting and disconnecting. This is not resolved unless I force the gamepad to restart. With my Airpod Max, while they are seen in the connection settings, they very rarely will connect at all. I have done all the updates I can (at least I think I have) but it doesn't seem to have resolved the issue.
If there's more specific system info I can get, please do let me know.
