Gosuncn (RichLink) protocol
RichLink OBD and asset trackers using the Gosuncn UDP wire protocol with configurator Auth Code SMS setup — not a GT06 clone.

-
1
Install SIM and insert OBD
Use a data-capable plan. Insert the dongle, start the engine, and idle several minutes until GNSS and modem LEDs stabilize per the GD201 manual.
-
2
Copy Auth Code from RichLink configurator
Open the RichLink tool for this IMEI and copy the Auth Code — BYOD renders it as the SMS
{login}placeholder. -
3
Send Gosuncn server SMS
Text the gosuncn_sms server command with Traxelio host, catalogue UDP port, and the Auth Code password.
-
4
Confirm UDP path
Ensure carrier firewalls allow UDP to the ingest host on the published port — TCP-only APN profiles will never deliver packets.
-
5
Verify first platform fix
Wait for an outdoor fix, then confirm the device row shows recent positions on the Gosuncn listener before fleet rollout.
Still offline after GPS lock
Gosuncn still not landing
- SMS sends but device never reports
Check three separate gates: Auth Code (not PIN), UDP carrier path (not TCP-only), and live Gosuncn decode on the listener. A correct SMS with no decoder still shows silence.
- Platform shows encrypted gibberish payloads
Firmware may have AES-256-ECB enabled. Route the device through a Gosuncn profile that matches encryption settings — GT06 decoders will never parse these frames.
