How to read ELD data with FMX00A

From Wiki Knowledge Base | Teltonika GPS

Terms and definitions

Acronyms and terms used in the document:

  • BT – Bluetooth;
  • ELD – Electronic Logging Devices.

Introduction

This document contains information required for developing an application for receiving Electronic Logging Devices data via Bluetooth from FMC00A and FMM00A series devices.

The ELD synchronizes with the CMV engine to automatically record:

  • Engine power status
  • Vehicle motion status
  • Miles driven
  • Engine hours
  • Identification of driver/authorized user, vehicle, and motor carrier
  • Duty status


Configurable parameters

ELD functionality has 3 additional parameters:

Parameter ID Parameter Type Default Value Value Range Value Parameter Name
Min Max
40000 Uint8 1 0 3

0 - Disable
1 - OBD
2 - ELD
3 - Non-OBD compliant

OBD Feature
40002 Uint16 10 2 65535 Seconds ELD data send period
40008 Uint8 0 0 1 0 - Disable

1 - Enable

Send ELD data via Bluetooth


ELD APP workflow

ELD functionality start to send data periodically via BT right after external BT device has been connected if OBD Feature (parameter ID 40000) is set to ELD (option 2). ELD data sending is paused if Configurator is connected. ELD data is resumed after configurator disconnects. ELD data sending resumes automatically when external BT device reconnects after connection loss.
