D2Sphere Key / Value Specification

Specification

• key[X] is specified as a ASCII String as key non-quoted
• keys with leading '_' like '_cell_rat' is reserved for predefined keys by D2Sphere
• value[X] is specified as a ASCII String quoted (String,Hex or Base64)
• single key/value pattern line must not exceed 4kbyte

D2Sphere SFAL TCP connector incommig message

$<sfal.data key1='value1' key2='value2' keyX='valueX'>" CRLF
$GPRMC CRLF (optional)
$ .... CRLF (optional)
$<end> CRLF

additional key value will be handeled as well for following SFAL data frames

$<sfal.data key1='value1' key2='value2' keyX='valueX'>" CRLF
...
$<sfal.pos key1='value1' key2='value2' keyX='valueX'>" CRLF
...
$<sfal.event key1='value1' key2='value2' keyX='valueX'>" CRLF
...
$<sfal.*** key1='value1' key2='value2' keyX='valueX'>" CRLF

PFAL to send key value to server

$pfal,Tcp.Client.send,0,"<sfal.data key1='value1' key2='value2' keyX='valueX'>"
