I am looking for an eval kit recommendation which can support a turnkey working demo to a COTS bluetooth headset. I imagine a WICED module is appropriate.

The WICED module should stream an I2S input/output corresponding to the headset speaker/microphone. A simple casted pairing to a fixed headset is only required for a proof-of-concept system which has no OS.

I've worked with Pioneer Kit PSoC 4 modules in the past, but I imagine WICED is the new path.

Long RF range of 250 feet is ideal to ensure a decent link w/ low probabilty of comm loss. Does the below module seem appropriate and what is the best dev kit to be able to break out an I2S link to my custom hardware:

Thanks for any recommendations.

Hi @Yashu ,

I believe you are trying to use CYW20706 as A2DP sink/source? CYBT3330xx-02 modules are good fit. You can also check CYBT-343026-02 module- https://www.cypress.com/documentation/development-kitsboards/cybt-343026-eval-ez-bt-module-arduino-e...

Now that all new Bluetooth products are supported in ModusToolbox (MTB), I would suggest you to use ModusToolbox. We have plenty examples available using MTB on Cypress Github.

For audio examples, you can check-

https://github.com/cypresssemiconductorco/mtb-example-btsdk-audio-watch

https://github.com/cypresssemiconductorco/mtb-example-btsdk-audio-headset

Also, you can check Cypress solution CYW20721B2 for audio applications.

Thank you. However, I incorrectly stated my requirement. I am looking to create the following item:

https://www.jkaudio.com/daptor3.htm

using a "Master mode" to allow pairing to a COTS headset device. However, I need an I2S stream instead of analog I/O signals.

Is the "Audio Gateway" the demo for this capability?
