    CYW43364 external coexistence

    user_1743026

      Hi

       

      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[] =

              // # The following parameter values are just placeholders, need to be updated.
