nRF7002DK, Set region return no error on wrong country code but after 10s

With NCS 3.4.1, I'm calling ret = net_mgmt(NET_REQUEST_WIFI_REG_DOMAIN, iface, &regd, sizeof(regd)); but if the country code is invalid, the function return after 10s but with no error code.

If i look into the code, the timeout should be 2s but an error make it divide by 20 and multiply by 100:

Can the nRF7002 return an error instead of not returning anything ?
Can the net_mgmt() return an error code in case of timeout ?
Can nordicsemi provide the list of supported country code ? So i can test myself and return quickly in case of invalid country code

Hi,

I added this function to the wifi/sta sample, and called it just after net_mgmt_callback_init() in main() function:

static int wifi_set_reg(void)
{
	struct net_if *iface;
	struct wifi_reg_domain reg = { 0 };
	int ret;

	reg.oper = WIFI_MGMT_SET;
	uint8_t low = 'X'; uint8_t high = 'Y';
	iface = net_if_get_first_wifi();
	if (iface == NULL) {
		LOG_ERR("No Wi-Fi interface found");
		return -1;
	}

	reg.country_code[0] = low;
	reg.country_code[1] = high;
	reg.force = false;

	ret = net_mgmt(NET_REQUEST_WIFI_REG_DOMAIN, iface, &reg, sizeof(reg));
	if (ret) {
		LOG_ERR("Regulatory setting failed %d", ret);
		return -1;
	}

	printk("Regulatory set to %c%c for interface %d\n", reg.country_code[0],
		reg.country_code[1], net_if_get_by_iface(iface));

	return 0;
}

int main(void)
{
	int ret = 0;

	net_mgmt_callback_init();
	wifi_set_reg();
	....

And the output is as follows:

00:00:11.840,270] <err> wifi_nrf: nrf_wifi_fmac_set_reg: Failed to set regulatory information
[00:00:11.840,301] <err> wifi_nrf: nrf_wifi_supp_set_country: nrf_wifi_fmac_set_reg failed
[00:00:11.840,362] <err> wpa_supp: wpa_drv_zep_set_country: set_country op failed
[00:00:11.840,454] <err> wpa_supp: Failed to set country code 'XY'
Regulatory set to XY for interface 1

meaning that net_mgmt() returns 0 (success) in this scenario, and uses 10 seconds to return.

Clear bugs from our side, which I will report internally. Thank you so much for notifying us and helping us improve our delivery!

Kind regards,

Håkon
