1
Insert SIM with data plan + airtime
Confirm the SIM works for data in a phone first. MVT-series devices have a single multi-purpose LED · a dead SIM and a config issue look identical from the LED alone.
-
2
Connect over USB-to-serial (recommended)
Open Meiligao Manager on Windows, plug in the USB-to-serial cable, click
Read Parameters. This is faster and more reliable than SMS for the first config · you see the full parameter table at once. -
3
Point the device at your server
In Manager, set Main Server IP/host to
your-server.comand port to5009. Or via SMS:adminip,000000,your-server.com,5009#. The default admin password is000000· change it after first config.adminip,000000,your-server.com,5009# apn,000000,internet# gprs,000000# -
4
Change the admin password
password,000000,<new_password>#· default000000is a security liability on a SIM that could receive any SMS. Pick a 6-digit value and store it with the device record. -
5
Confirm first position arrives
Send
status,<password>#and watch your server log for the heartbeat (command 0x0A) followed by the first position (command 0x9955) after a clean boot with GPS lock. No traffic after the reboot · re-check APN (silent failure mode #1).

Meiligao still not landing
- Device sends one packet, server decodes garbage, then nothing
Almost always a header confusion ·
$$is not unique to Meiligao (a few other protocols use the same bytes). Check the BCD device-ID field at offset 4 · if it's not 7 BCD bytes matching the printed device ID, the listener is auto-routing to the wrong decoder. Bind Meiligao to its own dedicated port instead of multiplexing.
