Two Simultaneous Bluetooth connections

Help! “Automatic” audio transfer of MFi iPhone to iPad and back and forth does not work well!!!

Very often freezes up, requiring turning all 3 devices off and rebooting them just to make a simple phone call this morning when the last night’s prior use was iPad. Even though all hearing aids and iPad/iPhone are constantly within 12 feet of each other and the WiFi without walls.

Yes, all software on all devices is up to date.

Need two simultaneous Bluetooth connections in HAs. Understand Phonak has this. Others? Hard to find listing of that capability in online descriptions. Does anyone know how to research or have list?

Thanks!

I am aware of “Hand Off” for iOS Apple devices but I have not seen two simultaneous bluetooth connections to one set of Oticon Real hearing aids. Someone here might have a better answer.
