Navigil Protocol

Navigil sequenced binary on Traccar TCP 5025 with acknowledgment reply headers and multi-report parsers.

Connect your tracker

Enter the tracker IMEI first, then verify your email and continue setup.

Quick answers

Stock port?

TCP 5025.

ASCII $T,?

No — sequenced binary with NavigilFrameDecoder.

Why acknowledgments?

Decoder sends reply headers; some units wait on them.

Navigil speaks sequenced binary on TCP 5025. NavigilFrameDecoder feeds NavigilProtocolDecoder, which acknowledges with reply headers (sendAcknowledgment) and parses several report classes: unit reports, TG2 reports, position report variants, snapshot4, and tracking data. Attributes include antenna state, battery/charge, satellite counts, odometer/distance, flags, and IO prefixes.

Sequence + ack discipline

Unlike fire-and-forget ASCII lines, Navigil’s open decoder expects sequenced frames and emits acknowledgments. Missing acks can stall a unit that waits for header confirmation.

Sibling contrast

Alematics on 5140 is $T, ASCII over a TCP string pipeline — not Navigil’s binary report catalog.

Setup walkthrough

  1. 1

    Confirm Navigil binary firmware

    Not Alematics $T, sheets and not HTTP phone apps.

  2. 2

    Server TCP 5025

    Host + 5025; reboot.

  3. 3

    Verify ack exchange

    Capture both device report and server acknowledgment headers.

  4. 4

    Check antenna/sat fields

    gpsAntennaState and satellite counts diagnose sky view before host blame.

Common troubleshooting

Aimed at Alematics 5140

Retarget to 5025; $T, ASCII will not satisfy Navigil binary reports.

Unit retries forever

Ack headers may be blocked by a middlebox; allow bidirectional TCP.

Positions sparse

Confirm which report type is enabled (position vs snapshot vs tracking data).

FAQ

Frequently Asked Questions

Same as Galileo tags?

No. Navigil uses its own sequenced report parsers on 5025, not Bitrek tag maps.

Command provisioning?
