The TKController App was originally developed to allow owners of the TK102B and compatible GPS Tracking devices to easily configure and arm the device from their phone. The app now supports multiple device types that use different SMS message formats and that have different features. If a suitable device type is not already defined in the app or you are experiencing problems with the app, please contact us (with a link to the manual for your device if possible) and I will endeavour to add support for your device. This is a “hobby project” so updates and new devices are implemented when time allows.
Even within the “TK-102” devices there are a number of firmware revisions/versions in use that are subtly different in their SMS command formats and functions. Varying both by version and manufacturer. The app can be updated with support for different versions by request.
Currently the app supports devices branded as “TK-102B” and “TK102-2” (Xexun manufactured) and also a unit branded/designated as the TLT-2H.
The current version on the app store also has support for the TK102 style device manufactured by WynnYeen which is designated as their model: GPS002, support for the Byte TK 104 and also a spurious TK 106 model that uses an unusual command syntax.
The list of specifically supported devices and links to their manuals can be found here. This isn’t a definitive list as such because many devices share the same command syntax so although a device may be designated “TK 102-2” that same device definition can be used with other devices in the same family (TK 103, TK 104, TK 105 etc…). If you have a device that isn’t currently supported then please contact us with the details and it will be added to the app.
The trackers offer a cheap and flexible security option, offering monitoring and tracking of vehicles, people and pretty much anything else.
The app has a number of functions to compose and send the commands the tracker understands. Where applicable the parameters of the command are definable.
Stockade (Geo fence)
This function instructs the tracker to send an alert if the tracker (or the vehicle/person it is with) move outside an area you define. For new stockades the app uses your iPhone/iPod’s current location as the centre of the stockade and allows you to define the distance that the stockade area will extend in all directions. The tracker uses a rectangular area and this is shown in the map view as a red rectangle.
As well as defining new stockades you can choose to save stockades that you use regularly, both their centre position and the selected distance. For example, you might want a standard stockade for the car park at work or your home.
Variations in GPS signal can reduce the accuracy of the GPS fix and the quality of the GPS signal (or the lack of it) may mean that you need to use a relatively large stockade distance to avoid false alarms. 300 metres is normally a safe distance, in good GPS signal areas you can reduce this, in bad areas (under trees etc…) you may need to increase this.
If you need to monitor the movement of the tracker over time you can create a track request. You can define the frequency of the updates (minimum 20 seconds, maximum of 255 hours) and how many times the tracker should send an update (forever/until cancelled or up to 255 times). You will receive a text with the latest position, the speed the tracker is registering, the time and a link allowing the location to be viewed on a map.
The tracker contains a shock/vibration sensor that can be used to alert you should the tracker/vehicle be tampered with or is in a collision. For vehicular use this can alert you if someone were to access your vehicle while the shock sensor is armed.
The tracker can alert you if it moves location. This can only be used in areas with good GPS reception as false alarms can be frequent otherwise. Whilst the tracker does contain software that tries to reduce false alarms in practice it’s effectiveness can be limited, particularly in poor GPS reception areas.
Engine On/Engine Off
For devices that support this option (TLT-2H, for example) this allows you to enable/disable the engine or other electrical systems via SMS. For security and safety reasons this is a 2 stage process to prevent accidental use, you will need to “manually” confirm the request via SMS when prompted.
