Do remember that Bluetooth and WiFi 2.4 are using spectrum very near from each other. Apple is using Bluetooth LE that is less harmful for Bluetooth connection by a 2.4g wifi connection that might be affected from time to time. And openSPOT4 is using 2.4G band only.... so be aware. Here iPhone 13 Pro and OS4Pro.... working flawlessly since the begining.
