public AX25Message parse(byte[] body,
                         AX25Callsign src,
                         AX25Callsign dest,
                         AX25Callsign[] digipeaters,

parse in interface AX25Parser

Parameters:

body - byte array containing the message to be parsed

src - AX25Callsign of the sending station

dest - AX25Callsign of the destination (probably an APRS alias)

digipeaters - array of digipeaters AX25Callsigns from the original RF frame, or null to indicate no digipeaters

rcvTimestamp - the time in Java/Unix milliseconds since midnight Jan 1, 1970 UTC when this message was actually received (as opposed to any timestamp that might be embedded in the message body)

connector - Connector over which the message was received (null if from a file)

Returns:

the decoded AX25Message (if not decipherable, a DefaultMessage is returned)
