Hi,
we are communicating data over BLE and would like to use the I2S for voice to a bluetooth headset or handsfree.
Is this possible with the EZ-serial firmware loaded ?
Thanks in advance

Hi Viggo,
After installing WICED SDK , you can find several BT demo examples like SPP, A2DP , HFP etc.
I2S is not configurable from application. Only A2DP profile can use use it internally.
Please refer to below threads:

Hi Viggo,
As of now only SPP profile of BT classic is supported in our Ez-Serial FW .
Refer the user guide here: https://www.cypress.com/documentation/software-and-drivers/ez-serial-ez-ble-module-firmware-platform
Thanks & Regards,

Hi Anjana,
ok, so if we are using the CYBT-343026-01 for BLE data communication via EZ-serial we can't use it for I2S voice ?
Where can I find firmware for the module to use the I2S ?
Thanks & regards
Viggo

Hello,
If you are using Ez-Serial platform (https://www.cypress.com/documentation/software-and-drivers/ez-serial-ez-ble-module-firmware-platform ) , then you can't use I2S/A2DP.
If you want Audio application with CYBT-343026-01 along with BLE connection, you can develop custom application and program the module via WICED SDK ( https://www.cypress.com/products/wiced-software ) .
Getting started with 343026 & WICED: https://www.cypress.com/documentation/application-notes/an223400-getting-started-ez-bt-wiced-modules
You can refer to A2DP_sink demo application in WICED SDK for reference (/20706-A2_Bluetooth/apps/snip/bt/a2dp_sink) .
Thanks,
Anjana
