Referencing to this discussion Re: CYW920719B2Q40EVB-01 Build + Programme option not available in ModusToolbox , I have created this new topic as per your suggestion.

Dheeraj, I'm not using any external tool to download FW into CYW920719B2Q40EVB-01 and I have not changed anything related to program address or reset address. I have just shared you download.log file at this path D:\cypress\Audio-20719B2EVB01\audio\watch\build\CYW920719B2Q40EVB-01\Debug\download.log generated by ModusToolbox itself when board is programmed by ModusToolbox. I have made a short video showing CYW920719B2Q40EVB-01 is programmed by ModusToolbox then Wiced client control application is launched from ModusToolbox itself but still BR/EDR discovery start/stop and all other options are still grayed out. Please check this video:

Hi,

Just now we have noticed that you are using wrong board.

The board image which you have shared is CYW920719Q40EVB-01, which is having an older version of 20719 chip (vB1), and it is expected to work only with WICED SDK.  You will have to get the latest version (20719B2 chip) of evaluation kit, which is CYW920719B2Q40EVB-01 in-order to work with Modustoolbox IDE and BTSDK.

Please check this link: https://www.cypress.com/documentation/development-kitsboards/cyw920719b2q40evb-01-evaluation-kit

Thanks,

DheerajP_41, thanks for the clarification on the board revision details. Now 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,
