@Marvee Amasi I am using mongoose library . I wants to send data to AWS iot core . I tried the same thing with esp32 over wifi. Now I needs to implement on nucleoh745zi-q over ethernet. But I don't know where to link AWS certificate.

Hope you have your root CA certificate (amazon root CA 1), device certificate, and private key

@Marvee Amasi yes I have

The place you are when configuring the MQTT connection, you load the AWS IoT certificates into mongoose There

Load the AWS IoT certificates

mg_tls_opts cert_options;

mg_tls_opts cert_options;

Your device certificate

cert_options.cert = "/path/to/device_cert.pem";

cert_options.cert = "/path/to/device_cert.pem";

Your private key

cert_options.key = "/path/to/private_key.pem";

cert_options.key = "/path/to/private_key.pem";

Amazon root CA certificate

cert_options.ca = "/path/to/root_ca.pem";

cert_options.ca = "/path/to/root_ca.pem";

Then after u can Initialize the connection to AWS IoT as in

struct mg_connection *conn = mg_connect(&mgr, "ssl://ur-endpoint-stuff.amazonaws.com:8883", event_handler);

if (conn == NULL) {
    printf("Failed to connect to AWS IoT Core or anything u want to \n");
    return;
}

struct mg_connection *conn = mg_connect(&mgr, "ssl://ur-endpoint-stuff.amazonaws.com:8883", event_handler);

if (conn == NULL) {
    printf("Failed to connect to AWS IoT Core or anything u want to \n");
    return;
}

Then u shuld enable TLS with the provided certificates

mg_tls_init(conn, &cert_options);

mg_tls_init(conn, &cert_options);
