I am just an iPhone newbie using an old iPhone 6S that I asked my wife to give me, updated to iOS 14, as an “iPod” for an Apple Watch that I’m getting to control my HA’s through the Smart 3D app on the watch linked to the same app on the iPhone 6S.
But I’ve noticed that if you go to Settings, Accessibility, Hearing Devices, that there are two settings options CONTROL NEARBY DEVICES and AUDIO HANDOFF. Someone who knows might help us all out by commenting on their functions and how these settings options affect iPhone, iPad, N7, etc., BT or MFi connections. But since I have no other iOS devices to control or handoff to, I turned both these options off (I think they are both ON by default in iOS 14). But if the settings of these options are inherited from some previous settings, y’all might want to check, if you’re running iOS 14.x, what these options are set to.
I have been switching my HA’s between the iPhone 6S and a Samsung Galaxy Note 8 connection/control just by turning off BT on the first active device and switching on BT on the new, second active device. Whatever settings I’ve chosen on the first device usually transfer perfectly to the Smart 3D on the 2nd device. I did have a problem the other night where I had been connected to my Android phone and I planned to use the iPhone for controlling the TV streamer but for some reason when I made the BT switch the iPhone refused to recognize the TV Streamer 2 although it had worked great before. So to watch a Blu-ray disc, I had to go back to the Android phone but after the movie when I tested the TV Streamer 2 on the iPhone again, it worked perfectly once more?! So at least with ReSound, there seems to be a bit of flakiness at knowing Who’s on First?! (famous old Abbott and Costello routine!).
