    CYW43364 external coexistence




      I use cyw43364 with wiced.


      I want to use coex with third-party ble.

      I want to disable SECI Coex and to enable 3 wire Coex.



      below is array in wifi_nvram_image.h.


      Q1. I can't find nvram.txt. So I will change below parameter. Is this right?


      Q2. How should I change?


      Q3. What GPIO is coex pin?


      static const char wifi_nvram_image[] =
