Micodus MP90G‑SA connects to Traccar but never decodes (no device / no positions)

Wiltdawg 10 months ago

Environment

  • Traccar: traccar/traccar:latest (Docker)
  • OS: Linux (Docker Compose)
  • Timezone: Europe/London
  • Router: TP-LINK Deco. Port 5030 forwarded for TCP and UDP connections

Tracker

  • Model: Micodus MP90G-SA
  • Firmware: unknown (factory)
  • Transport: TCP
  • Server: track.example.com
  • Ports tested: 5030
  • SIM: working (device connects repeatedly)

Docker Compose

services:
  traccar:
    image: traccar/traccar:latest
    container_name: traccar
    ports:
      - "8082:8082"
      - "5055:5055"
      - "5030:5030"
    volumes:
      - ./logs:/opt/traccar/logs
      - ./data:/opt/traccar/data
      - ./traccar.xml:/opt/traccar/conf/traccar.xml
    restart: unless-stopped

Traccar configuration (traccar.xml)

<properties>
    <entry key='config.default'>./conf/default.xml</entry>
    <entry key='database.driver'>org.h2.Driver</entry>
    <entry key='database.url'>jdbc:h2:./data/database</entry>
    <entry key='database.user'>sa</entry>
    <entry key='database.password'></entry>
    <entry key='osmand.port'>5055</entry>
    <entry key='tlt2h.enable'>true</entry>
    <entry key='tlt2h.port'>5030</entry> 
    <entry key='database.registerUnknown'>true</entry>
    <entry key="logger.org.traccar.protocol">TRACE</entry>
    <entry key="logger.level">ALL</entry>
</properties>

The traccar.xml file is confirmed to be mounted and read inside the container.

What works

  • Traccar UI loads correctly
  • Traccar Client devices work and show positions
  • MP90G connects repeatedly over TCP
  • Raw hex packets are logged

What does not work

  • MP90G device never appears in the UI
  • No device ID is extracted
  • No authentication or position decode
  • No protocol decode logs even at TRACE level

Logs (MP90G connection)

INFO: [T84919026] connected
INFO: [T84919026: tlt2h < 92.40.169.75]

Only raw hex appears. There is no decoded output at any log level.
The device repeats this every ~60 seconds.

I've manually added a device using the IMEI, device ID, and device ID with leading zero, and none of these appear in the UI.

Amazing! Thanks Anton!

For anyone who arrives here, it uses the huabao protocol on port 5015. The device ID in Traccar is the ID returned from the "VERSION#" SMS, padded with a single leading zero.

Port 5015 and with leading zero on ID also works for Micodus MP90G-E. Protocol jt808
