How to set the right interval (time/speed)

I have downloaded BT747 desktop Java application. I would like to set the device to make one point every 5 seconds only when I'm moving faster than 3 km/h. It means when I stop at some place the device will be "paused". How can I do that?

There is a problem. I set on tab "Device settings" Log by Speed above 3 km/h and Fix every 5000 ms. Then I click the Set button. Disconnect, unplug device, plug device, connect. Immediately the time box is checked and set to 5 seconds. Itself. Why? I use Holux M-1000C.

Feature request: height/speed diagram


I'm new to GPS tracking and BT747. I got my iBlue 747A+ recently and I'm really happy there is such a good crossplatform OSS tool I can use.

Anyway, there might be a feature that BT747 not have but what would be nice to have: a diagram of hight/speed to time. The enclosing Windoze tool "GPS Photo Tagger" has such a feature (apparently - I didn't try it out: click).
