I need to use bluetooth headset with voice recognition, which almost works fine in some devices like S3, S4 and Samsung Grand. However, when I tried same on Nexus 7, I am getting
BluetoothHeadsetServiceJni : Failed to start voice recognition, status: 6
error when I am calling startVoiceRecognition() method. I am using the code from this SO page.
What are the possible reasons for this issue occur only in some devices? Is there any way to solve this issue?
I have been check as Narayan mentioned, I found BluetoothHeadset.STATE_AUDIO_CONNECTED does fire in nexus 7 as well some other ZTE devices, may be this is manufature fault or a that device does not support call and you are try to communicate via call_mode, I think there is only workaround to solve this issue
