Hello,

You can find relevance code for reference in at_cmd_mode_custom.c#L64-L168 and icmp_ping.c from the Modem Shell sample.

Best regards,

Maria

Please help check how to conect to dst ip?

1.socket cant find dst addr

sockfd = socket_create(true, AF_PACKET, SOCK_RAW, IPPROTO_IP /*or IPPROTO_RAW*/, NULL, NULL, NULL);

send(sockfd, &pkt, PING_PKT_SIZE, 0);

[<---] [2026-03-05 17:13:56:279] [DBG][Hub] <SOCKET> Create RAW socket
[<---] [2026-03-05 17:13:56:285] [DBG][Hub] <SOCKET> [_FD_7_] Create success: type=3, protocol=255, block=1
[<---] [2026-03-05 17:13:56:295] [INF][Hub] <SOCKET> [_FD_7_] Failed to send ping packet: Address family not supported by protocol family

2. socket cant support AF_PACKET protocol family
sockfd = socket_create(true, AF_PACKET, SOCK_RAW, IPPROTO_IP, NULL, NULL, NULL);

struct sockaddr_in addr_in = {0}; or

addr_in.sll_family = AF_PACKET;

struct sockaddr_ll addr_ll = {0};

addr_ll.sll_family = AF_PACKET;

sendto(sockfd, &pkt, PING_PKT_SIZE, 0, (struct sockaddr *)&addr_ll /* or &addr_in*/, sizeof(addr_ll));
