8 Configuration File formats

Configuration file holds the data to be programmed to the hub. Configuration file
used for programming can be in Binary format (.cfg) or JSON format (.json). Both
the files are generated when changes are done to the configuration items in the Hub.

8.1 JSON Format

JSON file uses human readable text to program. Json file starts with open brace "{"
and end with close brace "}". Number of properties using
separated by commas can be declared inside these braces. There should not be any
empty space or empty line. Use only below mentioned names (case-sensitive) in Json
File. Json file should be in the below given format.
Format:
{
"name":"value"
}
*use comma to separate when there are more entries.
Example:
{
"pid":"0x1234",
"did":"0x5678"
}
In this example, pid and did are configuration items and 0x1234and 0x5678 are the
new values.
