AWS IoT - Espressif X.509 MQTT Publisher

Setup

Edit the src/main.h file with the relevant information for your project and save it.

#ifndef MAIN_H

// Wifi Details
const char *ssid = "YourWifiSSID";
const char *password = "YourWifiPassword";

const String thing_id = "YourThingID";

// AWS MQTT Details
char *aws_mqtt_server = "YourAWSThingID.iot.ap-southeast-2.amazonaws.com";
char *aws_mqtt_client_id = "YourMQTTClientID";
char *aws_mqtt_thing_topic_pub = "Your/MQTT/Topic";

#endif

You will also need to edit the lib/AWS/IOT/src/aws_iot_certficates.c file based on the certificates you get when setting up a thing on the AWS platform.

// Example below, change this and the other two entries to your certificates

const char certificate_pem_crt[] = {"-----BEGIN CERTIFICATE-----\n\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\n\

-----END CERTIFICATE-----\n"};
