[PROBLEM] Issue with Blutooth in 4.1

[TheOldPresbyope]

Hi Kent,

For reference, I just ran a clean-slate test using iPhone, iPad and an ANKER SoundCore speaker with release 4.1 on Pi-3B, 3B+ and a 0W. The only issue I ran into was that I had to turn Bluetooth OFF/ON on my iPhone in order for it to see the 0W, otherwise no issues with discovery, pairing, connecting and playing music.

Email me if you run into issues tonight :-)

Hey Kent,

Bluetoothctl util can be used to see what Bluetooth profiles a particular paired device supports. The device needs to be paired but not connected.

Examples showing support for "Advanced Audio Distribu.." (A2DP) profile for both Anker SoundCore Speaker and iPhone.

Code:

Thanks. I emailed you some test results before I saw this. Expect an addendum.
