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[] =

Dear Customer,

Kindly get in touch with your module vendor to get the necessary support. Customers are not recommended to modify nvram parameters at all. Here are some relevant documentation:
