i tried your simple publisher example
and modified the parameter of mqtt_connect
from:
/* Send connection request to the broker. */
mqtt_connect(&client, client_id, NULL, NULL, 0, NULL, NULL, connect_flags, 400);
/* check that we don't have any errors */
if (client.error != MQTT_OK) {
fprintf(stderr, "error: %s\n", mqtt_error_str(client.error));
exit_example(EXIT_FAILURE, sockfd, NULL);
}
with the correct username and password to:
/* Send connection request to the broker. */
mqtt_connect(&client, client_id, NULL, NULL, 0, "paul", "paula", connect_flags, 400);
/* check that we don't have any errors */
if (client.error != MQTT_OK) {
fprintf(stderr, "error: %s\n", mqtt_error_str(client.error));
exit_example(EXIT_FAILURE, sockfd, NULL);
}
i received no errors and a connection which worked.
then i tried wrong username and wrong password
/* Send connection request to the broker. */
mqtt_connect(&client, client_id, NULL, NULL, 0, "otto", "otto", connect_flags, 400);
/* check that we don't have any errors */
if (client.error != MQTT_OK) {
fprintf(stderr, "error: %s\n", mqtt_error_str(client.error));
exit_example(EXIT_FAILURE, sockfd, NULL);
}
i received no errors and no connection to the broker was established
after pressing the ENTER key to send the time i received an error
