I got a report of this via email from a customer, and was able to confirm on my end as well.
The current Beta version has an issue with reconnecting and/or remembering Wiimotes. Rolling back to 5.0-18498 fixes the issue.
I'm not sure if this should be filed as a bug just yet, as it could possibly be a configuration issue on me and the users part. Typically when a release breaks bluetooth passthrough, I get many emails, but on this occasion I've only gotten 1 so far.
My Repro Steps, for what they are worth:
1. Grab 5.0-19368 and enable Bluetooth Passthrough with an official adapter.
2. Load up a game and sync a wiimote.
3. Exit the game.
4. Load up another game; observe that your wiimote will no longer connect.
5. Attempt to sync the wiimote; observe that the wiimote cannot be resynced.
6. Reset pairings in controller options.
7. Exit Dolphin, unplug/replug the adapter, and start Dolphin again.
8. Repeat the steps above; observe you can essentially only pair and use the wiimote once.
These issues do not occur with the previous release though, only current.
