Can't find 20706 or 20735 boards in the Project Explorer Window

[btguy]

Hi,

I am trying to build Bluetooth Classic Audio device.

I am using 20706 & 20735 boards. I'm a beginner with your boards and software tools.

I installed WICED Studio 6.6.1.1 on my Windows 10 machine.

When I connect both the dev boards, I see them listed in my ports on the device manager also.

On first-time execution of the IDE, it did not prompt me to select the default platform. Ideally, I'd like to select the 20735-B1_Bluetooth or 20706-A2_Bluetooth as mentioned on both the evaluation kits' user guides.

I only see "43xxx_Wi-Fi" listed in my Project Explorer window. I can't see either of the boards in the "WICED target selector" drop down either.

Please let me know how to make 20706 & 20735 show up in the target builder drop down and project explorer window.

My goal is to build and flash Bluetooth Classic HFP (HF & AG roles - not concurently) & A2DP (target and sink roles - not concurently) profiles on both of the eval kits i.e., 20706 & 20735

The WICED 6.6 only support wifi/combo devices. 

If you are developing new application, we suggest you to use the latest SDK Modus Tool Box.

The CYW20735 is not supported for new designs. We suggest to use the newer device CYW20835 instead.

Thank you for the suggestion for 20706. I was able to use ModusToolbox and program the device.
I'd like to ask a follow up question on 20706 - I programmed it with an headset application. Is there a way to hear the audio from the eval board? I've not noticed any analog audio output ports on the board.

I'd like to ask you how can I program the 20735 device? I understand that you mentioned 20735 is not supported for new designs. But, I'd like to take a look once anyway. I looked for the 20735 device in Modus Toolbox but it is not listed in there it seems. Could you please let me know what am I doing wrong?

The CYW20706 EVB only has the I2S port for audio/voice data. If you want to hear audio, you need to connect a audio codec or DAC to it. You can refer to the following blog:

https://community.infineon.com/t5/Resource-Library/A2DP-Sink-Example-on-CYW20706/ta-p/246388

For the CYW20735 device, it  is not supported any more in the ModusToolBox SDK. The device is removed from the latest btsdk.
