CYW20721: profile Functionalities!

gokulnath · ‎Oct 27, 2021

Hello!
I'm new to bT domain and I'm based in France & would like some assistance to choose the perfect Cypress module for my application.

My use case: BT Audio Earphones (HFP, A2DP, AVRCP & SPP together) , HFP slave initiating BT- reconnection incase of disconnection + Custom data commands 1) under HFP 2) under RFCOMM
My custom commands are to interface with another Encrypted BT HFP AG device as Walkie - Talkie.

My previous setup: WT32-IA under IWARP I'm able to achieve these above functions using the "ECHO" Command on IWARP API. now I'm planning to upgrade it to BT 5.0 specs & I'm looking to change to cypress.

Please suggest which product is best for my purpose & especially can I achieve the Custom data command + HFP reconnection? Also suggest me which cypress chip should I go for ?

Thanks for your input

Hello @gokulnath

The chip you have mentioned; CYW20721B2 is the BTBLE audio chip which will be suitable for your application.

You can use the chip either in embedded mode (with an application developed in our Modus Tool Box IDE ) or in HCI mode (in which you can use any host which sends standard HCI commands).

For embedded mode, we have couple of example projects available and the details can be referred from the Technical Brief available here: https://community.infineon.com/t5/Resource-Library/AIROC-Bluetooth-SDK-3-1-Technical-Brief/ta-p/2864...

I would also suggest you to contact any of our local sales FAE for quick support.

Regards,

Anjana
