SpeechRecognizer in background: Error Domain = kAFAssistantErrorDomain Code = 1700 "(null)"

Hello,


My app is Bluetooth supportive and I want to recognize the speech in background mode.


However, it is working only in the foreground.

(Exception: if its execution was originally started on UI thread then it works even in the background)


But without it, after my app goes to the background mode, I am getting an error message like:

Error Domain = kAFAssistantErrorDomain Code = 1700 "(null)"


Is there anything I have missed or is it the limitation that iOS doesn't support SpeechRecognizer under background mode?
