Issues with the Wi-Fi driver interface

Hi,

There are some incorrect configurations in your prj.conf. You should remove the following Kconfigs:

CONFIG_NET_L2_WIFI_MGMT=y
CONFIG_NET_CONFIG_SETTINGS=y

You must also change CONFIG_NET_NATIVE from n to y and increase the stack sizes of CONFIG_NET_MGMT_EVENT_STACK_SIZE and CONFIG_HEAP_MEM_POOL_SIZE. Lastly, you must enable the WPA supplicant with CONFIG_WPA_SUPP.

Here is the modified prj.conf:

#wifi settings
CONFIG_WIFI=y
CONFIG_WIFI_NRF700X=y
CONFIG_WPA_SUPP=y

# Networking
CONFIG_NETWORKING=y
CONFIG_NET_L2_ETHERNET=y
CONFIG_NET_NATIVE=y

CONFIG_NET_UDP=y
CONFIG_NET_TCP=y

# Enable network management
CONFIG_NET_MGMT=y
CONFIG_NET_MGMT_EVENT=y

CONFIG_INIT_STACKS=y

# Memory and Stack Settings
CONFIG_HEAP_MEM_POOL_SIZE=153600
CONFIG_MAIN_STACK_SIZE=4096

# Debugging and Logging

Hi Marte,
thanks for the quick response!
I added .band to the params but i still get the same return. i have added my source code if that helps to recreate my problem.

devzone.nordicsemi.com/.../030265.main.c devzone.nordicsemi.com/.../wifi_5F00_driver.h devzone.nordicsemi.com/.../wifi_5F00_driver.c
thanks in advance.
Kind regards,

JonasR

Hi,

You are missing the band parameter in the connection request parameters struct. I tested your code in lesson 2 exercise 2, and I was able to connect after adding band like this:

int8_t wifi_connect(char* ssid, char* passkey)
{
    struct net_if *iface = net_if_get_first_wifi();
    if (iface == NULL) {
        LOG_ERR("No Wi-Fi network interface found!");
        return -ENODEV;
    }

    struct wifi_connect_req_params params = {
        .ssid = ssid,
        .ssid_length = strlen(ssid),
        .psk = passkey,
        .psk_length = strlen(passkey),
        .channel = WIFI_CHANNEL_ANY,
        .security = WIFI_SECURITY_TYPE_PSK,
        .mfp = WIFI_MFP_OPTIONAL,
        .timeout = SYS_FOREVER_MS,
        .band = WIFI_FREQ_BAND_UNKNOWN,
    };

    int err = net_mgmt(NET_REQUEST_WIFI_CONNECT, iface, &params, sizeof(params));
    if (err) {
        LOG_ERR("Wi-Fi Connection Failed (Error: %d)", err);
        return err;
    }

    LOG_INF("Connecting to Wi-Fi: %s", ssid);
    return 0;
}

Best regards,
Marte
