Hello,
I am attempting to connect to a Wi-Fi network using Exercise 2 from Lesson 2 of the Wi-Fi training in Nordic Academy. However, when I try to connect to the network, I encounter a -134 error while executing the following function:
net_mgmt(NET_REQUEST_WIFI_CONNECT, iface, &cnx_params, sizeof(struct wifi_connect_req_params));
Here's my main.c
