nRF9160 SICA B1A, mfw 1.3.5, NCS 2.4.0
Using the v2.4.0, lesson 5, exercise 2, solution and adding the setup for DTLS CID with
sock = socket(AF_INET, SOCK_DGRAM, IPPROTO_DTLS_1_2);
if (sock < 0) {
LOG_ERR("Failed to create CoAP socket: %d.\n", errno);
return -errno;
}
int cid = NRF_SO_SEC_DTLS_CID_SUPPORTED;
err = setsockopt(sock, NRF_SOL_SECURE, NRF_SO_SEC_DTLS_CID, &cid, sizeof(cid));
if (err) {
LOG_ERR("Failed to setup socket security DTLS CID supported, errno %d (%s)\n", errno, strerror(errno));
cid = NRF_SO_SEC_DTLS_CID_ENABLED;
err = setsockopt(sock, NRF_SOL_SECURE, NRF_SO_SEC_DTLS_CID, &cid, sizeof(cid));
if (err) {
LOG_ERR("Failed to setup socket security DTLS CID enabled, errno %d (%s)\n", errno, strerror(errno));
return -errno;
}
}
/* STEP 7.1 - Set peer verification to be required */
enum {
NONE = 0,
OPTIONAL = 1,
REQUIRED = 2,
};
int verify = REQUIRED;
err = setsockopt(sock, SOL_TLS, TLS_PEER_VERIFY, &verify, sizeof(verify));
if (err) {
LOG_ERR("Failed to setup peer verification, errno %d\n", errno);
return -errno;
}
I get an error: "errno 109 (Protocol not available)"
Are there any samples to show, how that works?
