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.
This is working well with the tracker I ask for couple of fixes and there work so got say big thank you and hope more come download it from now on cheers
