GPS103 Message Parser

This is a GPS103 GPS Tracker message parser implementation. It can be used to implement your own server. It parses all messages received from the device and creates the response message, if needed.

Usage

const Gps103 = require('gps103');
const net = require('net');

var server = net.createServer((client) => {
  var gps103 = new Gps103();
  console.log('client connected');

  client.on('data', (data) => {
    try {
      gps103.parse(data);
    }
    catch (e) {
      console.log('err', e);
      return;
    }

    if (gps103.expectsResponse) {
      client.write(gps103.responseMsg);
    }

    gps103.msgBuffer.forEach(msg => {
      console.log(msg);
    });

    gps103.clearMsgBuffer();
  });
});

server.listen(serverPort, () => {
  console.log('started server on port:', 4711);
});
