Problems related to nrf5340 brighton/off

[ozoz05]

Hello.
We are testing nrf5340 - nrf7002 using the example of blpovisioning.
I try to put on/off function using button, but if I reset pcb and turn on, it will connect to wifi and tcp server normally, but if I turn on -> off -> an error occurred in bt hci.
I looked it up
devzone.nordicsemi.com/.../473790
github.com/.../files
It's related, so I modified the nrf53_support.c file and built it

[00:00:20.508,056] <err> net_arp: Gateway not set for iface 0x20002718

This error is occurring.

Is there any additional data to refer to??

The sdk you are using is v2.8.0

Hi

So the error you're looking for here seems to come from the arp.c file in ...\v2.9.0\zephyr\subsys\net\l2\ethernet\arp.c In the net_pkt() function it seems to check if the destination IP is specified, and returns the "Gateway not set for iface" error if it is not specified.

struct net_pkt *net_arp_prepare(struct net_pkt *pkt,
				struct in_addr *request_ip,
				struct in_addr *current_ip)
{
	bool is_ipv4_ll_used = false;
	struct arp_entry *entry;
	struct in_addr *addr;

	if (!pkt || !pkt->buffer) {
		return NULL;
	}

	if (net_pkt_ipv4_acd(pkt)) {
		return arp_prepare(net_pkt_iface(pkt), request_ip, NULL,
				   pkt, current_ip);
	}

	if (IS_ENABLED(CONFIG_NET_IPV4_AUTO)) {
		is_ipv4_ll_used = net_ipv4_is_ll_addr((struct in_addr *)
						&NET_IPV4_HDR(pkt)->src) ||
				  net_ipv4_is_ll_addr((struct in_addr *)
						&NET_IPV4_HDR(pkt)->dst);
	}

	/* Is the destination in the local network, if not route via
	 * the gateway address.
	 */
	if (!current_ip && !is_ipv4_ll_used &&
	    !net_if_ipv4_addr_mask_cmp(net_pkt_iface(pkt), request_ip)) {
		struct net_if_ipv4 *ipv4 = net_pkt_iface(pkt)->config.ip.ipv4;

		if (ipv4) {
			addr = &ipv4->gw;
			if (net_ipv4_is_addr_unspecified(addr)) {
				NET_ERR("Gateway not set for iface %p",
					net_pkt_iface(pkt));

				return NULL;
			}
		} else {
			addr = request_ip;
		}
	} else {
		addr = request_ip;
	}

	k_mutex_lock(&arp_mutex, K_FOREVER);

	/* If the destination address is already known, we do not need
	 * to send any ARP packet.
	 */
	entry = arp_entry_find_move_first(net_pkt_iface(pkt), addr);
	if (!entry) {
		struct net_pkt *req;

		entry = arp_entry_find_pending(net_pkt_iface(pkt), addr);
		if (!entry) {
			/* No pending, let's try to get a new entry */
			entry = arp_entry_get_free();
			if (!entry) {
				/* Then let's take one from table? */
				entry = arp_entry_get_last_from_table();
			}
		} else {
			/* There is a pending ARP request already, check if this packet is already
			 * in the pending list and if so, resend the request, otherwise just
			 * append the packet to the request fifo list.
			 */
			if (k_queue_unique_append(&entry->pending_queue._queue,
						  net_pkt_ref(pkt))) {
				NET_DBG("Pending ARP request for %s, queuing pkt %p",
					net_sprint_ipv4_addr(addr), pkt);
				k_mutex_unlock(&arp_mutex);
				return NULL;
			}

			entry = NULL;
		}

		req = arp_prepare(net_pkt_iface(pkt), addr, entry, pkt,
				  current_ip);

		if (!entry) {
			/* We cannot send the packet, the ARP cache is full
			 * or there is already a pending query to this IP
			 * address, so this packet must be discarded.
			 */
			NET_DBG("Resending ARP %p", req);
		}

		if (!req && entry) {
			/* Add the arp entry back to arp_free_entries, to avoid the
			 * arp entry is leak due to ARP packet allocated failed.
			 */
			sys_slist_prepend(&arp_free_entries, &entry->node);
		}

		k_mutex_unlock(&arp_mutex);
		return req;
	}

	k_mutex_unlock(&arp_mutex);

	net_pkt_lladdr_src(pkt)->addr =
		(uint8_t *)net_if_get_link_addr(entry->iface)->addr;
	net_pkt_lladdr_src(pkt)->len = sizeof(struct net_eth_addr);

	net_pkt_lladdr_dst(pkt)->addr = (uint8_t *)&entry->eth;
	net_pkt_lladdr_dst(pkt)->len = sizeof(struct net_eth_addr);

	NET_DBG("ARP using ll %s for IP %s",
		net_sprint_ll_addr(net_pkt_lladdr_dst(pkt)->addr,
				   sizeof(struct net_eth_addr)),
		net_sprint_ipv4_addr(&NET_IPV4_HDR(pkt)->dst));

	return pkt;
}

I added a snippet from  NCS 2.9.0 here. How do you set the IP address in your application exactly?

Best regards,

Simon
