Quick answers

Port?

TCP 5157.

Hallmark fields?

Archive, priority, event, odometer, ADC1/ADC2.

Binary?

No — ASCII grammar.

Commands?

None on M2cProtocol.

Same as BSTPL?

No — different prefix and engine-field focus on 5241.

M2C packs a long ASCII telemetry sentence: protocol marker, IMEI, index, archive flag, priority, event, date/time, lat/lon, altitude, course, speed, satellites, odometer, input/output bits, power, battery, and two ADC channels. Traccar serves it on TCP 5157.

Dense ≠ IoTM binary

IoTM’s story is door matrices. M2C’s story is archive/priority/event headers plus dual ADC in ASCII. Mixing those support macros creates false “same thin shell” overlap.

BSTPL$ is another neighbour

BSTPL on 5241 announces itself with a BSTPL$ prefix and CAN-ish engine fields. M2C does not use that marker.

Setup walkthrough

  1. 1

    Match the long ASCII sheet

    If the manual shows archive/priority columns, stay on M2C.

  2. 2

    APN, then 5157

    Reboot into the dense sentence stream.

  3. 3

    Verify ADC and odometer columns

    Confirms you are not on a short heartbeat dialect.

  4. 4

    Watch archive flag while offline

    Understand whether the unit marks buffered records.

  5. 5

    Bundle one full sentence for review

    Length itself is evidence.

Common troubleshooting

Short heartbeats only

Wrong protocol or report profile — enable full telemetry.

ADC stuck

Sensor wiring or disabled analog channels in firmware.

Priority always zero

Some firmwares never set priority; not always a fault.

Frequently Asked Questions

Why care about archive flags?

They explain late points after coverage gaps without blaming the map.

UDP?

Stock M2C is TCP.
