I’m working on implementing SignalR communication protocol, It uses SSE(Server-Sent Events) communication, so once connected, one socket needs to remain open to receive new data, and we also need to send other messages over an additional socket.
I’m getting a fault when using a second socket, I set it up in the same way as I made the first one. I am modifying the solution found https://devzone.nordicsemi.com/f/nordic-q-a/100826/nrf7002dk-and-tls-sockets--7100-error/433368 to do this. It always faults weather the first socket gets used or not.
Here is the code to create the sockets (changes nslookup to google from my domain):
int sock;int sock2;int err;struct sockaddr_in *sa;struct addrinfo *rp;
struct sockaddr_in *sa2;struct addrinfo *rp2;
nslookup("google.com", &rp);print_addrinfo_results(&rp);
nslookup("google.com", &rp2);print_addrinfo_results(&rp2);
printk("Connecting to HTTP Server:\n");
// Load in the TLS cert for HTTPStls_credential_add(CA_CERTIFICATE_TAG, TLS_CREDENTIAL_CA_CERTIFICATE, ca_certificate, sizeof(ca_certificate));
// Create Socketsock = socket(rp->ai_family, rp->ai_socktype, IPPROTO_TLS_1_2); // IPPROTO_TCP //IPPROTO_TLS_1_2if (sock < 0){ printk("Error creating socket\n"); return (-1);}// TLS settingssec_tag_t sec_tag_opt[] = { CA_CERTIFICATE_TAG,};err = setsockopt(sock, SOL_TLS, TLS_SEC_TAG_LIST, sec_tag_opt, sizeof(sec_tag_opt));if (err < 0){ LOG_ERR("Failed to set TLS security TAG list. Err: %d", errno); (void)close(sock); return -errno;}
err = setsockopt(sock, SOL_TLS, TLS_HOSTNAME, HTTP_HOST, sizeof(HTTP_HOST));if (err < 0){ LOG_ERR("Failed to set TLS_HOSTNAME option. Err: %d", errno); (void)close(sock); return -errno;}
// Iterate through until we get a successful connectionfor (; rp != NULL; rp = rp->ai_next){ if (rp->ai_addr->sa_family == AF_INET) { // IPv4 Address sa = (struct sockaddr_in *)rp->ai_addr; sa->sin_port = htons(443);// this should be 443 (HTTPS port number) connect(sock, (struct sockaddr *)sa, sizeof(struct sockaddr_in)); if (sock > 0) break; }}
// Create Socket 2
sock2 = socket(rp2->ai_family, rp2->ai_socktype, IPPROTO_TLS_1_2); // IPPROTO_TCP //IPPROTO_TLS_1_2
if (sock2 < 0)
{
printk("Error creating socket\n");
return (-1);
}
sec_tag_t sec_tag_opt2[] = {
CA_CERTIFICATE_TAG,
};
err = setsockopt(sock2, SOL_TLS, TLS_SEC_TAG_LIST,
sec_tag_opt2, sizeof(sec_tag_opt2));
if (err < 0)
{
LOG_ERR("Failed to set TLS security TAG list. Err: %d", errno);
(void)close(sock2);
return -errno;
}
err = setsockopt(sock2, SOL_TLS, TLS_HOSTNAME,
HTTP_HOST, sizeof(HTTP_HOST));
if (err < 0)
{
LOG_ERR("Failed to set TLS_HOSTNAME option. Err: %d", errno);
(void)close(sock2);
return -errno;
}
// Iterate through until we get a successful connection
for (; rp2 != NULL; rp2 = rp2->ai_next)
{
if (rp2->ai_addr->sa_family == AF_INET)
{
// IPv4 Address
sa2 = (struct sockaddr_in *)rp2->ai_addr;
sa2->sin_port = htons(443);// this should be 443 (HTTPS port number)
connect(sock2, (struct sockaddr *)sa2, sizeof(struct sockaddr_in));
if (sock2 > 0)
break;
}
}
