AWSCertCP: AWS IoT SDK details

IoT Device SDK

---------------

The AWS IoT Device SDK for Embedded C (C-SDK) is a collection of C source files under the MIT open source license that can be used in embedded applications to securely connect IoT devices to AWS IoT Core. It contains MQTT client, HTTP client, JSON Parser, AWS IoT Device Shadow, AWS IoT Jobs, and AWS IoT Device Defender libraries. This SDK is distributed in source form, and can be built into customer firmware along with application code, other libraries and an operating system (OS) of your choice. These libraries are only dependent on standard C libraries, so they can be ported to various OS's - from embedded Real Time Operating Systems (RTOS) to Linux/Mac/Windows. You can find sample usage of C-SDK libraries on POSIX systems using OpenSSL (e.g. Linux demos in this repository), and on FreeRTOS using mbedTLS (e.g. FreeRTOS demos in FreeRTOS repository).

AWS IoT Javascript SDK

----------------------

This package is built on top of mqtt.js and provides three classes: 'device', 'thingShadow' and 'jobs'. The 'device' class wraps mqtt.js to provide a secure connection to the AWS IoT platform and expose the mqtt.js interfaces upward. It provides features to simplify handling of intermittent connections, including progressive backoff retries, automatic re-subscription upon connection, and queued offline publishing with configurable drain rate.

AWS IoT Arduino SDK 

-------------------

The AWS-IoT-Arduino-Yún-SDK allows developers to connect their Arduino Yún compatible Board to AWS IoT. By connecting the device to the AWS IoT, users can securely work with the message broker, rules and the Thing Shadow provided by AWS IoT and with other AWS services like AWS Lambda, Amazon Kinesis, Amazon S3, etc.

AWS IoT Device SDK For Java

--------------------------

The AWS IoT Device SDK for Java enables Java developers to access the AWS IoT Platform through MQTT or MQTT over the WebSocket protocol. The SDK is built with AWS IoT device shadow support, providing access to thing shadows (sometimes referred to as device shadows) using shadow methods, including GET, UPDATE, and DELETE. It also supports a simplified shadow access model, which allows developers to exchange data with their shadows by just using getter and setter methods without having to serialize or deserialize any JSON documents.

AWS iOT SDK for Python

---------------------

The AWS IoT Device SDK for Python allows developers to write Python script to use their devices to access the AWS IoT platform through MQTT or MQTT over the WebSocket protocol. By connecting their devices to AWS IoT, users can securely work with the message broker, rules, and the device shadow (sometimes referred to as a thing shadow) provided by AWS IoT and with other AWS services like AWS Lambda, Amazon Kinesis, Amazon S3, and more.

AWS IoT SDK for CPP 

-------------------

The simplest way to use the SDK is to use it as is with the provided MQTT Client. This can be accomplished by following the below steps:

Build the SDK as a library, the provided samples show how this can be done using CMake

Include the SDK code as is in the client application. The SDK can be built along with the client code

To get basic MQTT support, only the mqtt/Client.hpp file needs to be included in the client application. This contains a fully featured MQTT Client. The client expects to be provided with a Network Connection instance. Further details on this are below Depending on the client application, other files such as Utf8String.hpp, JsonParser.hpp and ResponseCode.hpp might also need to be included.
