TK102 GPS server - DEPRECATED

This package is no longer being maintained.


Receive and parse GPS data from Xexun TK102 trackers.

The Xexun TK102 is a GPS device that can send coordinates over TCP to a server via GPRS. This Node.js script creates a TCP server that listens for GPRMC data, parse it and send the data to your post-process function. The parsed data is provided in a clean easy to use object, so you can easily store it in a database or push to a websocket server, etc.

Example

var server = require ('tk102');

// start server
server.createServer ({
  port: 1337
});

// incoming data, i.e. update a map
server.on ('track', function (gps) {
  updateMap (gps.geo.latitude, gps.geo.longitude);
});

Prepare device

Assuming your simcard has enough SMS and data credits and the TK102 is configured for your provider's APN, simply send adminip123456 IP PORT where obviously IP is the server's IP, PORT is the port to listen on and 123456 is your admin password. :) It cannot take hostnames as it has no dns features on board.

Activate sending coordinates: t030s003n123456

This tells the device to send its location AFTER each 30 seconds and no more than 3 times. 30 seconds is the minimum. Send t030s***n123456 to go on for infinity.

  • s (seconds) can also be m (minutes) or h (hours)
  • To end tracking send notn123456

Installation

Stable: npm install tk102

Develop: npm install fvdm/nodejs-tk102#develop

Settings

name type default description
ip string 0.0.0.0 Listen on IP, 0.0.0.0 is all IPs
port integer 0 Listen on port, 0 is random (see listening event)
connections integer 10 Maximum simultaneous connections
timeout integer 10 Idle time out in seconds
server.createServer ({
  ip: '1.2.3.4',
  port: 0
});

Events

The server emits the following events about the server status and incoming GPS pushes.

track

( gpsObject )

The data push from the device.

server.on ('track', function (gps) {
  { raw: '1203301642,0031698765432,GPRMC,144219.000,A,5213.0327,N,00516.7759,E,0.63,179.59,300312,,,A*6D,F,imei:123456789012345,123',
    datetime: '2012-03-30 16:42',
    phone: '0031698765432',
    gps: { date: '2012-03-30', time: '14:42:19.000', signal: 'full', fix: 'active' },
    geo: { latitude: 52.130326, longitude: 5.167759, bearing: 179 },
    speed: { knots: 0.63, kmh: 1.167, mph: 0.725 },
    imei: '123456789012345' }
})
property description
raw the input string without trailing whitespace
datetime the device 24h clock
phone the admin phonenumber that initiated this tracking
imei device IMEI
gps information about the GPS signal
geo geographical position and direction
speed travel speed

gpsObject.gps

property description
date date as received from GPS
time time in 24h UTC as received from GPS
signal signal strength, either full or low
fix GPS fix, either active or invalid

gpsObject.geo

property description
latitude position latitude
longitude position longitude
bearing direction in degrees

gpsObject.speed

property description
knots speed in knots per hour (original)
kmh speed in kilometer per hour
mph speed in miles per hour

data

( rawString )

The raw unprocessed inbound data.

server.on ('data', function (raw) {
  console.log ('Incoming data: '+ raw);
});

listening

( listeningObject )

Very useful to find out random port (0).

server.on ('listening', function (listen) {
  // listen = { port: 56751, family: 2, address: '0.0.0.0' }
});

connection

( socket )

Emitted when a connection is established with the server, includes the socket basics.

server.on ('connection', function (socket) {
  console.log ('Connection from '+ socket.remoteAddress);
});

disconnect

( socket )

Emitted when a connection is ended, includes the socket basics.

server.on ('disconnect', function (socket) {
  console.log ('Disconnected device '+ socket.remoteAddress);
});

timeout

( socket )

Emitted when a connection expires, includes the socket basics.

server.on ('timeout', function (socket) {
  console.log ('Time-out from '+ socket.remoteAddress);
});

fail

( Error )

Emitted when data cannot be parsed. Useful for debugging device issues.

Error is an instanceof Error with .stack trace.

server.on ('fail', function (err) {
  console.log (err);
});

error

( Error )

Emitted when a server related error occured.

Error is an instanceof Error with .stack trace.

Messages

error description
Server error Catch server failures
Socket error Catch communication failures
IP or port not available This catches EADDRNOTAVAIL errors
server.on ('error', function (err) {
  console.log (err);
});

log

( name, data )

Emitted on any of the above events. Useful for debugging and logging.

argument type description
name string Event name, i.e. track
value mixed Data from the event
server.on ('log', function (name, value) {
  console.log ('Event: ' + name);
  console.log (value);
});

Notes

There is no security built in, anyone could push data to your server.

The parsed object is based on a lot of testing in the field and incomplete documentation, I hope I got it right. There are many variations of the TK102 tracker available with each different data formats. It may be possible your device or even mine is one of the clones and incompatible with this module.

If you can, please provide multiple responses from the data event in a Github issue (public) or contact me directly, your data is handled confidentially. Preferably leave the device tracking with an interval of 30 seconds or less for about 3 to 5 minutes outdoors or near a window. This way I can figure out the data format and various states the tracker reports about itself to the server.
