    BR/EDR Disconvery start/stop does not work in WICED client control application for CYW920719Q40EVB-01

    anje_2248446

      I have installed the latest WICED Studio version 6.4

      With this I'm able to successfully program CYW920719Q40EVB-01 provided applications like audio gateway or audio watch examples.

       

      Now, when I try to use client control application when audio watch example is programmed in the device, BR/EDR discovery start/stop buttons are enabled. But when I press start discovery button, nothing really happens and BR/EDR devices near by (which are in pairing mode) does not get discovered by device and client control application BR/EDR discovery drop down list is empty. So, I'm not really able to test AV Source (A2DP source) feature.

      Here is the BTSpy Log:

      But if I flash audio gateway example application in the device, then I press BR/EDR discovery start button in client control application, it successfully discovers the near by BR/EDR devices (which are in pairing mode). But the audio gateway application does not support AV Source (A2DP source) feature which I want to test. Please help.

       

      thanks,
