Is your GPRS Tracker safe ?

When you want to know where you've been using GPS, you basically have two options: active tracking and passive tracking.

Passive tracking is what most users of this site are doing: an electronic devices stores the positions internally and these positions are recovered at  a later time.

Active tracking generally implies the transmission of the current position to some kind of server in "real time".  And that is most of the time done using the GSM/GPRS network.

Tracking dogs - CollierGPS

Collier GPSCollier GPS

When I discovered about 'Kookoo', the tracked cat back in May, I had no idea that I was going to work on a project to track dogs.  And yet, I did.

If you are interested in this amazingly well designed collar, you can find more information in French at and a demonstration of the interface, but here is my story:

BT747 2.0.0 is out!

I have released BT747 2.0.0.

The 1.68.32 was generating enough confusion as it is no longer keeping up with the latest device evolutions and many people were still downloading it.

The 2.X.XXXX versions will continue to exist and correspond to the development builds.

The new directories on Sourceforge are 'Stable' and 'Developement' for the corresponding builds.

iPhone/iPod compatibility getting closer

BT747 finally made a first working run on a jailbroken iPod.  BT747 was used to make a conversion of a '.bin' log file to 'KML' and 'KMZ' using its Command Line Interface (CLI).

Hopefully the author of roqyBluetooth will respond so that the Bluetooth communication can be added.  With that the CLI should be able to get logs from our preferred loggers.

Then a GUI implementation on the iPhone/iPod is amongst the possibilities, but that would be up to an iPod/iPhone owner to do so.

Faster thumbnail creation

Thumbnail creation is finally faster (in most cases).  That's something I wanted to do since a while.

BT747 now tries to use the thumbnail data that is already in the JPG files to create its own thumbnail.  That avoids the requirement to read the entire JPG file to do that.

That's available starting from version 2.X.1763 .
