I have a CC3200 EVK and I am testing the Wifi Audio demo app which was provided by TI in SDK example.

Is this application work for Full duplex communication by turning on both the Mic and Speaker on both the Modules ?

    Hi Nachiket,

    The demo in the SDK does support simultaneous bi-directional (full duplex) audio. This is achieved by exercising the two parallel paths (as described below) for the audio-in and audio-out paths.

     Audio-in jack -> 3200 McASP Data pin 1 -> I2S serializer 1 -> Audio Tx Task -> Audio transmit socket   --- Over the air

    Audio-out jack <- 3200 McASP Data pin 0 <- I2S serializer 0 <- Audio Rx Task <- Audio receive socket  --- Over the air

     

    Each of the paths are simplex individually but together it achieves the full duplex audio transfer.

    Best regards,

    Naveen
