Good day!

I have CYBT-353027-EVAL and gonna connect codec to it to make self-made CYW920721B2EVK-02. I like CYBT-353027 for it small dimensions and functionality. In the WICED-Studio it is a A2DP Sink example for CYBT-353027 but in ModusToolbox there is no such example for my board. In CYBT-353027 datasheet it is written that it can be a BT Classic Audio device, not only BLE. I selected CYW920721B2EVK-02 in ProjectCreator and generated the project. Now I would like to change files in generated project to make it suitable for my EVAL to work with them in ModusToolbox.

What are this changes in generated files? Thanks!

Best regards,

Dobre

You can create demo A2DP with CYW20706 device and change the platform files to adapt for the CYBT-353027.

CYBT-353027 is based on CYW20706. They are using different libs with CYW20721. 

To run the A2DP, it is better to create the demo based on CYW20706EVB.

Thanks for answering.

OK, I downloaded the demo based on CYW920706WCDEVAL into my CYBT-353027-EVAL. No effect. My smartphone doesn't see it. Any suggestion what to do to start development?

Best regards,

Thank you for answering. I am sorry for late answer - I expected some difficulties with COM ports. Now it's ok.

As far as I understand you tell about log in terminal. I use terminal application but don't see any log in it except of 1 0x00 byte. By the way when I tried examples from CypressAcademy for my CYBT-352027-EVAL I saw log messages. Any further suggestion?

Best regards,

May be I need to change some files? The example is for CYW920706WCDEVAL not for CYBT-352027-EVAL. GPIO pinout and settings are different. E.g. if I download A2DP Sink example in my CYBT-352027-EVAL I can't reprogram it any more until I use recovery and WICED_MOD_Programmer.exe

What are the right way to go?

Best regards,

Dobre

Could you use the WICED for your development as the device is supported on both WICED and Modus?

It is not convenient because there are a lot  examples for ModusToolbox and moderators advised us to migrate from old WICED to new ModusToolbox. That is why I want to concentrate on ModusToolbox and do all work in it and ask you what is the way to launch A2DP example (for CYW920706WCDEVAL) on CYBT-352027-EVAL (what files to change)?

Thanks in advance!
