GT06 Tracker


The GT06 tracker (may also be referred to as a TK100 GT06, according to the manual) uses similar command structures to the WynnYeen GPS002 with commands separated by hash (#) characters.

In addition to the stockade/geo fence options, this device can also control a relay remotely to allow vehicle circuits on/off.

The definition is still in review and may require an app update to be developed to give full support.

TK100 GT06 Manual

Deaohk TK102

This variation of the TK102 is the first one I’ve come across that doesn’t have a variable stockade feature. Or at least not according to the manual !

It has a simple move command that sets up a 200m stockade around the current position but that’s it.

I’ve implemented what commands I can for this device but it seems to rely quite heavily on using and reporting it’s position to a web site rather than sms. Currently there is a Track On/Off command that is experimental as it’s not really documented in the manual but may work… If you have one of these, please let me know if it works or not !

The manual also suggests that the shock alarm is an optional feature so may or may not work depending on your device firmware.

I’ve found a manual online, available at the link below which should help identify if this is your device…

Deaohk TK102


This is from an, as yet, unidentified manufacturer and appears to be of the TK102 design.

The firmware, however, is quite limited compared to most of the other TK102 versions out there with a subset of SMS commands and a very primitive stockade command.

The stockade command is the main indicator that you have one of these devices, the manual showing the stockade command as:


So it has no way to define the centre of the stockade and, I assume, just uses it’s current position as the centre.

I have been sent a scanned manual by the user that first reported this device type but have not yet found an online version suitable for inclusion here.


This is a new 3G tracker which uses a completely different command set but still has a similar feature set to other devices.

The command set is case insensitive but I have chosen to use upper case for the commands, as per the manual, to make it clearer.

The accompanying manual for the tracker is available here… TK119-W 3G Manual

It seems to be a vehicle oriented tracker, taking a wide voltage input range (6-36V) so it can be powered directly on pretty much any vehicle. It also has a relay control so the fuel pump or some other cutout can be used to immobilise the vehicle remotely.

Unlike the majority of trackers this device does not use a password, relying instead on the caller ID to authorise. I’m not sure if this is a security risk or not at this stage as I’ve not had a unit myself to experiment with.

Xexun XT-009

This seems to have pretty much the same functionality as the TK102 but with the addition of an external power/fuel cut facility. For some reason it has the latitude and longitude reversed when compared to all the other models I’ve seen so far.

It’s a dedicated vehicle mounted tracker so connects to a 12v power supply and also has an “ACC” input that can be hooked up to the ignition or other power source and the unit will send an alert if it sees 12v on that input, such as when the ignition is powered on, when this function is armed.

The stockade/geo-fence command looks like this…

stockade123456 114.124845E,22.56718 5N;114.777888E,22.55 5666N

It also uses an unusual auto tracking command that looks like…

China TK 106

Screen Shot 2014-10-29 at 18.59.18This device is from an unknown manufacturer and uses a strange form of the Xexun command set. The command format differs from the Xexun though in that it sends the password as the first part of the SMS message instead of after the command.

Other than that it appears to be very similar to the TK 102 in terms of functionality.

The manual used to configure this device type is: TK106 Manual

The stockade command for this device looks like:

password+stockade 22589155N,113.827732E;22. 559000N,113.897111E

The shock alarm command looks like:

password+shake 5


Byte TK 104

Screen Shot 2014-10-29 at 18.45.30This is a very similar device to the Byte TK 102B and uses almost all the same commands.

The main difference from the app’s point of view is that, being specifically for use in vehicles, it has the ability to remotely switch a relay. With the correct installation the relay can be used to enable and disable the vehicle by cutting power to the fuel pump or another circuit that the engine relies on to run.

The primary difference between using the TK 102B device and the TK 104 device type is that, with the latter, you get stop engine and start engine buttons.

A manual for the supported device is here: TK-104 Manual

The command for the stockade looks like this:


The commands to stop and start (resume) the engine via the relay are:


The shock command is:



WynnYeen GPS002

tk102bAnother variation of the TK-102 style device but with a unique command set that seems to have been created from scratch by WynnYeen. This device was not fully available in the app prior to the v1.3 release due to the command formats required.

The Geofence/stockade feature on this device uses a circular area with a radius rather than a rectangular area. It’s capabilities seem very similar to the Xexun TK 102-2 unit albeit that the SMS commands are completely different ! The geofence also includes a “time” element which may help reduce false alarms when the gps signal throws up a location glitch.

The manual for this unit is available here: GPS002 Manual

The SMS command for geo fencing for this unit looks like this:


the vibration/shock sensing command looks like this:

#vibrate#grade level#password#

I believe that, as with other TK 102 units, this manufacturer also produces versions of the TK 103, TK 104, TK 105 and TK 106 that use a similar command set and may well be compatible with this device setting.


TLT-2HThis was the first tracker that the app supported that deviated completely from the TK command set. The commands are not just variations on the TK command set but are unique to this device. It gave me a few headaches modifying the app to support it but, in so doing, it allowed the app to be more flexible for future devices.

It’s a good little device, especially for vehicle tracking (often sold as a motorbike tracker) as it’s waterproof, powered from 12v and has the ability to switch a relay that can be used to remote disable the vehicle.

It uses command numbers instead of words so 004 is used instead of stockade, for example.

The manual that I used for the device implementation is this one: TLT-2H Manual

Unlike the TK family of trackers, this one uses a circular geofence. The geofence command looks like this:

004+ user password E/Wddd.dddddN/Sdd.dddddRzzz.z

The “disable vehicle” command is a two stage process, requiring two different commands and this is reflected in the app’s button layout when this device type is selected.

TK 102-2

tk102bI believe this is the Xexun unit. The commands are very similar to the TK-102B with enough subtle differences to make life awkward ! It looks, on the outside, identical to the TK-102B but comes from a different manufacturer and the command set seems to match those that are listed in the Xexun manuals.

The user manual for this device is available here: TK102-2 Manual

The obvious differences in the commands between this and the TK-102B are those for the geo fence and for the shock/movement sensing. Again the TK102 is only the “baby” of the range and the same commands are also used for versions of the TK103, TK104 and TK106 etc… The TK102-2 designation is, I believe, the Xexun original for the TK102B.

If your device manual shows the geo fence format as looking like this: (no space between coordinates, compared to TK-102B)


and the shock/shake command has a sensitivity option on the end:


Then this device type is probably the most compatible with your device.
