JT/T 808 Protocol (Chinese National Standard)
Binary TCP protocol mandated by the Chinese Ministry of Transport (交通运输部) for fleet-grade GNSS terminals · the wire format every Chinese-compliance GPS tracker speaks. Used by Howen, Streamax, Concox compliance variants, and hundreds of OEM dashcam manufacturers worldwide.

1
Check the device's OEM configurator path
JT/T 808 hardware varies by manufacturer (Howen, Streamax, Concox compliance variants, JIMI compliance variants). Check the model's manual for the canonical config method · SMS, AT-command serial console, or vendor cloud configurator.
-
2
Set the server endpoint via SMS or AT
Most Chinese-OEM JT/T 808 devices accept SMS commands like
*SERVER#TYPE,1,your-server.com,5015,0#· check the model's exact command sheet. Vendor portals usually expose the same settings via web UI. -
3
Set the APN
*APN#your_carrier_apn,,,#(Sinotrack-derived JT/T 808 firmware) or vendor-specific equivalent. APN must be correct before any data session opens. -
4
Reboot the device
*RESET#or hard power-cycle. The device authenticates via Registration (0x0100) + Authentication (0x0102) packets · server replies with general response (0x8001) on accept. -
5
Validate the 0x7E framing arrives intact
If positions don't arrive, capture a TCP dump on the server · packets should start and end with
0x7E. If you see garbage bytes inside the body, the firmware likely mis-implements the escape rule · contact the OEM for a firmware update.

Still offline after GPS lock
JT808 still not landing
- Position checksum errors flagged on a fraction of packets
Common cause: device firmware mis-implements the escape rule (forgetting to un-escape the body before computing the checksum). Two paths: (1) firmware update from the OEM (often fixes); (2) Traxelio's decoder has a tolerant mode that accepts checksums computed either pre- or post-escape · check the model's known-quirks list.
- Streamax dashcam DVR uploads positions but video stream fails to start
Video streaming is JT/T 1078 (separate protocol on a separate port), not JT/T 808. The 808 telemetry endpoint and the 1078 streaming endpoint are configured independently · check the device's video-streaming settings and confirm the 1078 endpoint points at Traxelio's streaming ingest (separate from the 5015 telemetry port).

FAQ
JT808 leftover questions
Why is the protocol called JT/T 808 and not just JT 808?
JT/T is the Chinese transport-ministry standards series · the slash is part of the official name. JT = Jiao Tong (transport), T = Tielu (rail-related industries). The 808 is the standard number. Operators casually drop the slash when writing in English · both JT/T 808 and JT808 are common in the wild and refer to the same standard.
Can I use JT/T 808 hardware outside of China?
Yes · the protocol itself is country-agnostic. Many Western fleets unknowingly run JT/T 808-compliant hardware (especially in motorcycle, asset-tag, and budget-fleet deployments) because the Chinese OEMs default to it. Traxelio decodes the protocol regardless of where the device is deployed.
