WICED Studio Bluetooth

Hello -

I'm considering using the CYW20706 for a Bluetooth audio headphone application.  It will be connected to an external DSP and power amp via I2S and be controlled by external MCU via UART.  The CYW20706 datasheet shows that the necessary ports are available to do this, but I noticed that audio headphone was not listed as one of the applications in the datasheet.  This has me concerned that there may be some limitations for audio applications.  Could someone tell me more about using CYW20706 in an audio application. 

The other key requirement for me is to be able to support iAP2 for communication with Apple devices over Bluetooth.  It seems like this is should be supported by the SDK, but I would like to confirm.

Thanks!

John

Hi John,

We have the example codes for HFP as well as iAP2 profiles.

Please go through it:

SDK : WICED studio 6.2

HFP - /20706-A2_Bluetooth/apps/snip/bt/hci_handsfree

iAP2 - /20706-A2_Bluetooth/apps/snip/bt/iap2

Thanks & Regards

Hi,

You can use A2DP sink for Bluetooth audio on 20706.

Refer the snip in WICED studio SDK (/20706-A2_Bluetooth/apps/snip/bt/a2dp_sink)

Also the following blog: WICED Studio Bluetooth Forums

Thanks & Regards,

Hi Anjana,

Thanks for the info and the links!  It's good to know that A2DP sink is possible.  How about using this part in HFP mode where audio data is both sent and received?  Would there be any issues?

Do you have any thoughts on implementing Apple's iAP2 communication using this part?

Thanks,

John
