That sounds frustrating, especially since it was working perfectly before. Since it suddenly started on both devices, it could be a recent iOS update or app-side issue rather than hardware. You might want to check if there’s a new app update or firmware update for the Mooshimeter, as compatibility bugs can cause this kind of connection loop. Also, try resetting network settings on your iPhone as a last step, it sometimes fixes persistent Bluetooth issues.

On a side note, if you want a break from troubleshooting, you can try something fun like this null brawl android version, which offers a smooth and fully unlocked gameplay experience.
