WICED Studio Bluetooth

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,

Anjana

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

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
