Hi Nir,
Do the following:
- Go to the Start Page in the PPW Configurator and double click the example project: CC85XXDK-Wireless Headset (see picture below)
- The default Master application role is Stereo headset base station. Change this to Mono headset. You can see in the details field that this application role configures the audio device to use microphone input.
- The default Slave application role is Stereo headset. Change this to Mono headset to correspond to the Master's role.
- Pair up and stream audio from the mic connector.
What is actually happening here is settings inside the audio device definition files (.ppwadd). For example if you open the aic3101.ppwadd in a text editor (this file is found here C:\Program Files\Texas Instruments\PurePath Wireless Configurator\audio_devices\) and scroll down to line 67 you see the section:
<cfg_sequence_filter_spec name="mic_input">
<application_role_list>Master/Mono headset,Slave/Mono headset,Slave/Stereo headset,Slave/Mono microphone,Slave/Stereo microphone</application_role_list>
</cfg_sequence_filter_spec>
Master/Mono headset is one of the application roles that uses "mic_input". If you search for mic_input in this text file you can see that it occurs several places. The point is that the aic3101 is configured differently based on whether the mic_input filter is enabled or not. Hope this was understandable.

Clik here to view.
