JSON is made up of two structures:
JSON is made up of two structures:
* A collection of name/value pairs. In various languages, this is known as an object, record, structure, dictionary, hash table, key list, or associative array.<br>
* A collection of name/value pairs. In various languages, this is known as an object, record, structure, dictionary, hash table, key list, or associative array.<br>
* An ordered list of values. In most languages, this is implemented as arrays, vectors, lists, or sequences.<br>
As this Codec is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language-independent but uses conventions that are widely known to programmers of the C family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal language for data exchange.<br>

JSON is an open standard file format and data exchange format used between FMBXXX devices and AWS IoT Shadow Service:
Its basic principles are:<br>

* AVL data will be uploaded to Amazon Web Services IOT Shadow service.<br>
* AVL data will be uploaded to Amazon Web Services IOT Shadow service.<br>
* AVL data is JSON key-value based<br><br>
* AVL data is JSON key-value based<br><br>
Data sending procedure and logic are the same as sending to regular servers, except data is being packed to JSON document as required in Amazon Shadow service.<br>

This codec is required to use in the Amazon AWS console, it is important to note that AWS uses TLS encryption protocol, and it must be set up the FMBXXX device properly into the AWS IoT service.<br>
