GPS Data Logger Software - BT747

It looks like Qstarz is going a similar way as Holux is: limiting device functionality for user friendlyness. This is not to the likings of some users of course, but to warn those, here is a list of limitations.  If you find any other, or some incorrect statement, leave a comment.

1. Time logging can not be set to 5Hz.  When setting logging to 0.2 seconds, logging is set to 5 seconds.  (This is what is reported, but I'ld like to see it confirmed by transaction logs).  The Fix Period has to be set to 200ms if this is meant to work anyway.
2. 5Hz logging can still be achieved by setting the fix period to 200ms and the speed condition to a minimum value like 1 km/h.  The distance condition possibly also works here.
3. Logging can not really be turned on/off by SW.  The 'nav/log/off' button of the logger is the master of this.  Technically, the device does respond correctly to instructions from the SW (BT747) to turn logging on and off, but the firmware checks/sets that value to the one that corresponds to the button position.  In nav mode, logging is set to off, and in log mode, logging is set to on.

That seems to be it, but as said, you can add comments to this post.

Hier ist eine Liste von Geräten mit denen BT747 arbeitet. Im allgemeinen unterstützt BT747 Geräte mit MTK/MTK II-Chipsatz.

Does this software support either of these two BT GPS loggers, should it work?

QStarz BT-Q2000 - http://www.qstarz.com/Products/GPS%20Products/BT-Q2000-F.htm

or

MainNav MG-950dm - http://www.mainnav.com/product/md-950dm.htm

Not sure what GPS chip set the QStarz unit uses, but I think the MainNav unit has the Mstar MSB 2212 chip set.

I actually have the Gosget-S2 http://www.gosget.com/en_show.asp?id=99 which seems to be exactly the same as the MainNav device.

Thought I would do a quick post on how I got my Qstarz BT-1300 (aka. Qstarz Travel Recorder Nano) working on Ubuntu and BT747.

I was getting this message when plugging it in the USB port:
