[Linphone-developers] Audio Problems on SDK version 5.3.58 - iOS version

[Jörg Rummler]

Hello Team,

I got Problems with connecting an Bluetooth Device and our ios-App. I'm using 
Callkit to Display the call and to change the Audio Device manual. When the 
incoming or outgoing Call starts the Bluetooth Device is checked and the audio 
is working correctly through Bluetooth.
When I'm now changing from Bluetooth to IPhone the Audio is now on Iphone. But 
when I'm trying to get back to Bluetooth Device, nothing happends and the audio 
stays on the Iphone.

Any Ideas whats going wrong?

Why is libliphone telling me that the Bluetooth Device is not in the device 
list?


Thanks, 
Jörg
