BT747 Debian Package in preparation

A debian package for BT747 is now in preparation.

I was contacted to see if I was willing to assist in that , which I agreed.  I made some updates already to make the packaging easier, but there is still some work to do by the packager.

Installing BT747 in Ubuntu 11.04 (Natty Narwhal) - Installing sun-java6

Every new version of an OS is subject to generating secondary effects and the latest Ubuntu version has an impact on BT747.

By default OpenJDK Java 6 is installed for the core java virtual machine and libraries and Icedtea to enable 'Java Web Start'.

Unfortunately that seems to result in some trouble here and there so I recommend to install the 'sun-java6' package instead.  Sun has been acquired by Oracle, but the package still is 'sun-java6'.

Your feedback regarding a port of BT747 to a paying license platform (iPhone/Android)

I've launched a poll to check the interest to have BT747 running on the iPhone and the Android platform with Bluetooth support.

To keep the effort as low as possible on my end, I would port BT747 to a platform called 'TotalCross' which is an evolved java like virtual platform of SuperWaba.  BT747 already runs on SuperWaba, so porting would be 'limited' effort.

However, the use of Totalcross is not free and it depends on how many licenses are procured.

Hence the purpose of the poll is to know two things:

  • How many of you are interested (only participate in the poll if you are concerned);
  • How much you are willing to pay (say 'nothing' if you are interested but will not pay a dime).

I'll organise the distribution of licenses, which will imply the license cost itself, transaction costs and a small fee for my effort.  The amount mentionned in the Poll is the total fee.So please, vote and at most once to get an idea if it is worthwhile to go that way!

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.

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:
