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,

Hi Aniket,

Can you try following procedure in Code flow and audio testing of demo.watch using CYW207xx devices and test the example?

Let me know if you still face the issue.

SheetalJ_96 thanks for the information.

I'm able to make it work after commenting out //hci_control_sleep_configure(); in watch.c and now with audio watch example flashed into the device using client control application able to scan, pair, connect with bt speaker. Also able to test AV Source (A2DP Source) audio streaming with sine wave as well as audio from .wav file.

But I would like to know if CYW920719Q40EVB-01 supports AAC CODEC and is it supported in the examples provided (audio watch example) in WICED Studio 6.4 (I think this is the latest), if yes how do I test AAC CODEC streaming ? I do not see any options visible in client control application related to AAC CODEC. Please provide some details on this topic.

thanks,

Hi Aniket,

CYW20719 does not support AAC. If that is a mandatory requirement for you, then please look at audio solutions CYW20721 and CYW20721B2.

FYI:Does WICED 6.2 support A2DP AAC codec on CYW20706 and CYW20719 ?

This applies for WICED 6.4 as well.
