AWS IOT Robot. Connect to AWS IoT cloud and save its state there. Interact with Remote Controller by publishing\reading messages in topics.

##Prerequisities

• Download AWS IoT SDK Embedded C here
• Download certificate authority CA file from Symantec (root certificate)
• Ensure you have created a thing through your AWS IoT Console with name matching the definition AWS_IOT_MY_THING_NAME in the aws_iot_config.h file
• Ensure the names of the cert files are the same as in the aws_iot_config.h file
• Ensure the certificate has an attached policy which allows the proper permissions for AWS IoT

1. AWS IoT Console - https://console.aws.amazon.com/iot/home
2. Create a Thing, Create and Activate a Thing Certificate, Create an AWS IoT Policy and attach it to a device (or just click "Connect a device" button and then certificate and policy will be generated automatically) Tutorial

###Connecting to the AWS IoT MQTT platform

Connecting to the AWS IoT MQTT platform

AWS_IoT_Client client;
rc = aws_iot_mqtt_init(&client, &iotInitParams);
rc = aws_iot_mqtt_connect(&client, &iotConnectParams);

Subscribe to a topic

AWS_IoT_Client client;
rc = aws_iot_mqtt_subscribe(&client, "sdkTest/sub", 11, QOS0, iot_subscribe_callback_handler, NULL);

Update Thing Shadow from a device

rc = aws_iot_shadow_update(&mqttClient, AWS_IOT_MY_THING_NAME, pJsonDocumentBuffer, ShadowUpdateStatusCallback,
                            pCallbackContext, TIMEOUT_4SEC, persistenSubscription);

API Documentation

###Config Need a config file to be started. Content:

• topic to publish (sent messages)
• topic to subscribe (get messages)
• QOS (0 | 1)
• field size (width, height)
• field (matrix)
• initial position: [i, j]
• initial direction (UP = 0, RIGHT = 1, DOWN = 2, LEFT = 3)
