traccar-node-client

A node client for pushing GPS updates from GPSD to a Traccar server

Notable features:

1. When network is down it will cache messages, allowing for full history when network resumes
2. different send rates for if the device is static or moving, allowing lower data rates for static devices.

Run it with node index.js after cloning the repo. Relies on GPSD being installed and running.

example config.json

{
    "gps_device": "/dev/ttyACM0",
    "gpsd_host": "localhost",
    "gpsd_port": 2947,
    "send_interval": 20000,
    "static_send_interval": 60000,

}

Config Options:

• "gps_device" - the device reported by GPSD
• "gpsd_host" - hostname/ip/url of machine running GPSD
• "gpsd_port" - GPSD port
• "send_interval" - interval between sending when not static (i.e in motion)
• "static_send_interval" - interval between sending when static (i.e not in motion)
• "static_distance_threshold" - distance in meters between GPS updates reported from GPSD to be classed as not "static"
• "static_distance_measure_time" - the number of milliseconds between GPSD updates to use to calculate distance moved.
  • the default values of 1m & 1000ms equates to ~2mph.
• "server_url" - traccar server url (inc. port) for OsmAnd updates
• "device_id" - Device ID to send to traccar
