Point this protocol at Traxelio
Teltonika Configurator (Windows USB-attached) for initial setup. FOTA Web (free cloud platform at fm.teltonika.lt) for fleets already deployed · no physical access needed.
In the GPRS section: Domain = your platform's host, Port = your platform's listener (Traccar default for Codec 8 is 5027), Protocol = TCP. Codec: Codec 8 Extended for FMB1xx-and-newer; Codec 8 for legacy FMB1xx pre-2018.
Modern firmware supports a primary + secondary endpoint. Useful for validation · push the same record to both your previous platform and the new one for a week before cutting over.
Click Save to Device · reboots automatically. Confirm the first decoded position in Traxelio.
Spot-check 2-3 devices on the new server · CAN bus / fuel / engine-hours channels should match what FOTA Web showed. If a channel is missing, the CAN profile likely needs loading via Teltonika's CAN Adapter Tool.

What Traxelio surfaces from these packets
Still offline after GPS lock
CAN profile not loaded · the device needs the right vehicle-specific CAN profile installed via CAN Adapter Tool (Mercedes Actros uses a different profile than Volvo FH or DAF XF). Without a matching profile, the device reports basic GPS only · the CAN side stays empty.
Two things to check: (1) APN configuration matches the SIM (FOTA Web defaults often work because Teltonika has APN auto-detect for common European SIMs; on African / Asian SIMs you need to set APN manually). (2) The IMEI is correctly registered in Traxelio · check the device's IMEI matches a TrackerDevice record before assuming a wire-protocol issue.
