Installing the Desktop Version of "MTK Data Logger Control BT747"

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.

BT747 on 64 bit windows

BT747 should be able to run on 64 bit windows when using the new RXTX version.
This has been included in the latest uploads of BT747 in the developement section on the sourceforge site but the correct scripting has yet to be confirmed.


As on all platforms, the following steps are needed:

  1. Install the serial link driver (for USB, to be done only once on a computer)
  2. Install the application
  3. Get the serial link to work (RxTx driver)

In more detail, it goes like this:

  1. Usually the USB driver comes on a CD with your device. If not, you can probably get them from (CP2102 VCP drivers)
  2. Installing the application as indicated elsewhere
