IMPORTANT: BT747 is updated with a CERTIFICATE to comply with JAVA 7 (1.7.0_51) security.
(I bought a trusted certificate (provided by a trusted authority) for about $300. Received it on Jan. 17, 2014.
Thank you (!) to the users that donated a bit (thanks!) to partially cover the cost of the certificate.
If every person using BT747 would donate $1 the cost would be covered in about two weeks (luckyly for you, I did not wait to cover the cost).
Installing the desktop version of BT747 for GPS control is fairly easy through the 'Java Web Start' system. This system works on Windows flavours, MacOS and Linux.
To download zip files follow this link.
On Ubuntu it is recommended to Install sun-java6 first
For easy installation (RECOMMENDED!), use one of these links:
Try the desktop version of BT747 or Install the desktop version of BT747
Try the development version, Install the current development version or keep it up to date automatically.
On recent machines or in case of trouble with the serial link: BT747 Latest using RxTx 2.2pre2 (RxTx dev version) for Windows 32 & 64 bit, MacOSX, Linux or Install the development version using RXTX2.2pre or Install the stable version using RXTX2.2pre
Code and versions for PC, MacOS, Palm, WinCE, Linux and Mobile Phone are available from the the project site. On Gentoo, BT747 is under sci-geosciences/bt747. On some systems you will need to install drivers and on MacOSX you will need to do some administrator operations if using BT747 with your GPS Logger for the first time. For MacOSX, you can find a good quick introduction here and others here. (On MacOS, you'll need to do a one-time 'sudo mkdir /var/lock' and 'sudo chmod 777 /var/lock').
If you have a 64 bit version of Windows and you are running a 64 bit version of Java, the stableserial driver will not work. Use the 2.2pre2 link above or install the 32 bit version of Java instead - you can get it on the sun site. In Linux, you can install it through 'sudo apt-get install ia32-sun-java6-bin ' as explained for Kubuntu.
If you are lacking web start on your system, it can be found on sun's site.
Remember: BT747 is software to manage most MTK based GPS logger devices. These are generally from Transystem, Holux, Qstarz, Konet, ... .
BT747 also exists for PDAs and for Java Capable Mobile Phones. These releases can be fetched on the project site. Very usefull to empty and configure your logger on the road.
P.S.: You might see a message that the certificat has expired and that it is not verified. This is correct. I might regenerate a certificate later on, but getting a verified one costs quite some money and this is freeware!
