Quick answers

Stock Traccar port?

TCP 5181.

Delimiter?

Frame split on $AP; payload starts PA$.

Field separator?

Hash # between date/time/lat/lon tokens.

C2STEK on Traccar TCP 5181 uses a CharacterDelimiterFrameDecoder on $AP. The decoded string matches PA$ + IMEI + $ + typed fields separated by # (date yymmdd, time hhmmss, valid flag, signed decimal lat/lon, speed, alarms).

$AP / PA$ dialect on 5181

CarTrack on 5061 uses ## / $$…&A…&B; Carscop on 5040 uses ^ and optional UB05 IMEI. C2STEK’s $AP delimiter plus PA$ prefix is unique in this wave.

Catalogue stance

Stock Traccar reference. Traxelio catalogues C2STEK as positions_only.

Setup walkthrough

  1. 1

    Configure TCP 5181

    Host + 5181; reboot.

  2. 2

    Capture PA$imei$

    If you only see $AP trailers without PA$, framing is incomplete.

  3. 3

    Check `#` separated decimals

    Lat/lon are signed decimals, not NMEA deg-min like Carscop.

  4. 4

    Read valid flag 0/1

    Flag 0 explains empty maps with otherwise healthy CSV.

Common troubleshooting

Confused with CarTrack $$

CarTrack is $$/## on 5061. C2STEK needs $AP/PA$ on 5181.

Delimiter swallowed

Decoder splits on $AP — firmware must emit that marker between frames.
