Hello Cypress Support team.

[Background]

We would like to evaluate hci_audio_gateway demo on the CYBT_343026_EVAL board. For this demo, we refer to an Application Instructions written in the below file.

WICED-Studio-6.4\common\apps\demo\hci_audio_gateway\hci_control.c

[Procedure]

1. Build and download hci_audio_gateway application to the board.

2. Start ClientControl application.

2-1.  Open Port on HCI UART port.

      Then, "BLE Discovery" and "BR/EDR Discovery" buttons are available. And the discovery behavior works well.

2-2.  Download .hcd file to the board.

      Then, "BLE Discovery" and "BR/EDR Discovery" buttons become DISABLED.   Those buttons are grayed-out.

[Question]

1) Is it necessary to download .hcd file for hci_audio_gateway demo?

2) If necessary, please let me know the correct procedure for this demo.

Thanks,

Yoshinori

Hi YoTa_1693656 San,

1) Is it necessary to download .hcd file for hci_audio_gateway demo?

A) No, it is not necessary to use .hcd file to test hci_audio_gateway demo. .hcd file is used to download application to RAM where as .hex to flash. Only thing is if you are using clientcontrol to download the application, only supported format there is .hcd . If you download the application directly from WICED SDK also , you can just open client control -> open port and start discovery & other operations. You don't have to download the same application again by client control via hcd file.

Thanks & Regards,

Anjana
