Example of using

prompt> node gps2mqtt-server.js

Prepare device

Assuming your simcard has enough SMS and data credits first of all you have configure the TK102 for your provider's APN

apn123456 <apn>

(example)

apn123456 web.omnitel.it
    

Then simply send

adminip123456 <ip> <port>

where obviously is the server's IP, is the port to listen on and 123456 is your admin password. It cannot take hostnames as it has no dns features on board.

(example)

adminip123456 34.251.136.219 1337

Setting time zone

timezone123456 <60*hour>

(example for Italy)

timezone123456 60

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.

To go on for infinity

t030s***n123456

s (seconds) can also be m (minutes) or h (hours)

To end tracking send

notn123456
