Firstly I'm not technical, so bear with me.
Which of the buttons would I click to use an MTK mini Data Logger as it is neither iBlue / Qstarz / Holux / Konet: or PhotoTrackr / ...: etc.
I have not clicked either of the buttons as I don't know if it would damage my logger.

Hi First off - there are only

First off - there are only a few BT747 commands that could 'break' your device and for each of them you need to confirm (twice). You can safely try the download buttons.

The specification you give is shared between all MTK devices so it will not help determine which one you actually have. After a search on the web, I found that this might best fit your layman definition:

GPS MINI Tracker (MTK GSM chipset) GK201

But that page also mentions SirfIII for the same device (they'ld need to make a choice!) and it seems to have a GPRS/GSM interface only.

So off on another search, based on the specification this time, where the battery capacity and the dimensions may be unique. This leads me to:

It is the first time that I see a reference to these devices! It is most likely that the 'iBlue/ ...' download button simply works. Let us know.

Sorry, I did not know you needed to know the model name.

Well it did start using iBlue, but as there is only a very few minutes of data to download, I dont know how long I'm supposed to wait for it to finish as it seemed to be going no where. I don't appear to be able to attach a file to these posts, so I have emailed the bin file to you Mario.

I have a similar issue.

I have a similar issue. Connected to my Windows, I can connect, but when I push download, nothing happens despite waiting for a couple of hours. Everything seems to be ok. I'm connected on COM3 , have the device on (Iblue), but alas no download... Hope you can help!

Solved! Wrong com port and

Solved! Wrong com port and wrong driver - my mistake...  Thanks for the programme!

John, I have the same problem


I have the same problem as you but i am wondering how you found out about drivers etc.
