If it happens that there is no your device in the drop-down list (right to Connect button in the first screen), open File menu and click on Find serial ports. That will re-list all available ports, including your device (if you paired it properly with you computer).

Threw everything (i.e. BT747 folder and .zip) in the garbage bin. Went again to :
http://bt747.free.fr/content/?q=webinstall

and clicked the first suggestion:

For easy installation (RECOMMENDED!), use one of these links:
Try the desktop version of BT747 or Install the desktop version of BT747

NOW IT WORKS ! GREAT !!
Thanks again for your help !

Doubleclicking the BT747_lwin.jnlp file results in an error message.
The Java web start says (in swedish) something like :

Unable to load resource: file:/mdeweerd/workspace/BT747/BT747_lwin.jnlp

My computer is PowerMac G5 DP 1.8 GHz with OsX 10.4.11. Could it be something with the hardware? Is the location of BT747-programfiles wrong ?

Thanks for the fast response!

Anders, please have a look at the comment I wrote to Cornelia, you might solve this problem exactly the same way by starting the .jnlp file.

Hi
I installed the latest version of BT747 i.e. BT747_1.68.7_full

Double clicking: bt747_macosX.command just results in this comment at Terminal:

Last login: Mon May 18 11:00:25 on ttyp1
Welcome to Darwin!
[Anders-DatorB:~] anders% /Applications/GPS/BT747_1.68.7_full/bt747_macosX.command; exit
tcsh: ROOT_DIR=/Applications/GPS/BT747_1.68.7_full: Command not found.
tcsh: ROOT_DIR: Undefined variable.
logout

What might be the problem? I just wanted to check that this program worked BEFORE I purchase the Holux. Now it seems I dont get it to run. I did follow the instructions about writing the commands in Terminal. Maybe I did go wrong there?

Thanks

Hello Jan,

it’s working fine (the install desktop version) – a thousand thanks (for your quick answere) from Germany

Cornelia, please try the Java Webstart way of starting BT747.
http://bt747.free.fr/content/?q=webinstall

–> Install desktop version

This will place a new icon on your desktop after clicking the downloaded the .jnlp file and I assume starting it this way will work because I can’t see that you’re doing something wrong here.

If not: there’s a new build for folks with serial link problems on that page as well, have a look at that one too.

Hi,
I am struggling for a couple of days now & need your help to get the HOLUX M-241 to talk with the BT747.
Anybody out there who can help me?

Following set-up/Version
- AppleNotebook bought in Jan 09
- CP210x Macintosh OSX Driver v2.1 Release Notes Copyright (C) 2008 Silicon Laboratories, Inc.
- Installed BT747, version
V1.68.5 starting via bt747_macosX_j2se.command

Is working fine, however once I plug in the HOLUX M-241 in the USB, and want to start the connection (buttom left corner) via USB I am getting the following error messages

Sorry, user error!
I get it now, you have to download it first and then convert it into the desired format.

Thanks!

Mikey, the raw data gets saved to the “raw log file” path in BT747′s “Log operations” tab. Are you sure you don’t see this file after downloading the track log from the GPS logger? I’m saving it to /Users/jan/GPS/in/BT747log.bin and never had any problems with that.

Hi, thanks a lot for the really good information about connecting the Holux to Mac via Bluetooth and I bought it upon your recommendation. The desktop version of BT747 is certainly much prettier than the old version and helps get over some of the “hassle” in using Bluetooth.

The trouble I have is that whilst I can see it download the data, I don’t know where it saves the file to. I’ve tried specifying different locations, but it still doesn’t work.

Any help or guidance would be appreciated.
Cheers!

Awsome! It works fabulus!

Splitting the tracks is really very useful, I tried it and it works great. And there is one more thing I found out while using my exported GPS tracks with Google earth.

Always when I opend a GPS track exported with the BT747 I got a wierd path in google earth. From a large high everything looked normal but as I zoomed in it was like some data of the path was missing. I was really frustrated about that so that I thought about switching to houdaGPS wich supports the Holux m-241 in the newest version. But with houdaGPS you only can download the data from your davice and convert it into one of three formats. And you always get only one file out of your device.

But what about the wierd path in Google earth. It’s all about the high. If you don’t see parts of your path it is becourse the high is below ground level. To see the full path select it in google earth and open the pathinformation by ctrl klick at the path. Go to the high tab and choose stick to the ground or choose a high by using the slider. If every point of your path is now abov ground level or if you stick it to the ground you should see the hole path.

I hope you understand what I was trying to say, sorry for my poor english, it’s not my native language.

Thank you Jan for this gead Blog.

Cheers mate
