Thank you. I tested a same CoreBluetooth code to connect to 3 or more devices on iPhone 15 Pro ( iOS 18.5) and Vision Pro (vision OS 2.5). It worked on iPhone but does not on Vision Pro. I suppose there is an issue or limitation of bluetooth connection on background or hardware. Does anyone have or resolve the same problem? And how should I detect when I cannot add connection, and successfully reconnect them?
