Binary data to JSON format converter
This bundle can be used to convert binary data to JSON format.
This bundle utilize awesome Java Binary Block Parser. See more details about the library and parse rule syntax from page Java Binary Block Parser.
Example usage:
// @formatter:off
/*
* Frame format:
* +----+----+-----+-----+-----+-------+-----+----+-------+
* | CC | 64 | F | <D> | <S> | <LEN> | <DATA> | <CRC> |
* +----+----+-----+-----+-----+-------+-----+----+-------+
* |<------------------ HDR ---------->|
* |<----- LEN ------>|
* |<-------------------- CRC -------------->|
*
*/
