This is a Gps103 GPS Tracker server implementation written in javascript. It parses all messages received from the device and creates the response message, if needed. Eventually it will send the received information to an MQTT broker.
So it acts as a server for Gps103 trackers and a gateway to MQTT.
Run a npm install after you cloned it and start it via node app.js.
You can create a .env file to configure the behavior off the app.
The following environment variables are recognized. If not defined a default will be used.
- GPS103_SERVER_PORT=64459
- MQTT_ROOT_TOPIC=gps103
- MQTT_BROKER_URL=localhost
- MQTT_BROKER_PORT=1883
- MQTT_BROKER_PROTO=mqtt
- MQTT_BROKER_CA=/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
- MQTT_BROKER_USER=user
- MQTT_BROKER_PASSWD=passwd
Messages received on the TCP port will be transmitted via MQTT MQTT_ROOT_TOPIC/IMEI/pos
For example: gps103/123456789012345/pos
