Enable Coex on CYW20706 - KBA228790

Version 5

    Author: AnjanaM_61       Version: **

     

    To enable Coex in a WICED® SDK application, call the wiced_bt_coex_enable(); API.

    Use GPIO_6 as the ‘SECI_IN’ pin and GPIO_7 as the ‘SECI_OUT’ pin of CYW20706 to connect to the Wi-Fi chip.

    Note that these two pins are internally hardcoded for coex functionality in the ROM firmware.

     

    See the following blogs for an overview and learn how to test coex on Cypress BT/Wi-Fi chips:
