Hi z2n,
I've a Holux M-241 GPS logger and here's a short description
what I've done to download tracks to my N800 (you need a shell and root access)!
1. By gpsbabel via USB
I've compiled gpsbabel version 1.3.6 for Diablo 4.1.2
and the missing USB-to-UART kernel modules. For the M-241 the
usbserial.ko and the cp2101.ko modules are required!
To read the track out you must first switch your N8x0 into the
USB host mode according to
http://www.internettablettalk.com/wi..._using_OS_2008
load the drivers by
insmod usbserial.ko
insmod cp2101.ko
connect the USB cable and then finally call
gpsbabel -t -i m241 -f /dev/ttyUSB0 -o gpx -F mytrack.gpx
2. By gpsbabel via Bluetooth
First you have to install the bluez-utils-test package from
http://repository.maemo.org/pool/dia...b/bluez-utils/
Then create a Bluetooth connection to your GPS logger by
hcitool cc <bt-address>
and bind the RFCOMM device /dev/rfcomm0 to the GPS logger
rfcomm bind /dev/rfcomm0 <bt-address>
Now you can call gpsbabel to read out the track data
gpsbabel -t -i m241 -f /dev/rfcomm0 -o gpx -F mytrack.gpx
The <bt-address> is the Bluetooth address of your GPS device,
like 00:1B:C1:04:F7:71. You can find it e.g. by calling
hcitool scan
For your QT-1300 you should try "-i mtk" instead of "-i m241"
as parameter for gpsbabel!
3. By bt747 via Bluetooth
I've successfully read out the track data by bt747 (version 1.68.7),
but the application is incredible slow on the N800 (see the attached
screen shot)! If you want to try it you have to install Jalimo from
https://wiki.evolvis.org/jalimo/index.php/Maemo
together with the optional packages
classpath-gtk, librxtx-jni and librxtx-java! Then you can use my
modified run_rxtx.sh script to start bt747. If /dev/rfcomm0 does not
exist the script will do the job for you! Therefore you have to
replace the <bt-address> in line 4 and 5 by the address of your GPS
device!
The run_rxtx.sh script, gpsbabel version 1.3.6 and the USB-to-serial
Kernel modules described above are included in the attached gpslogger.zip
archive!
Suggestions and ideas to make alls this more user friendly are welcome...

I'm leaving on a trip tomorrow (hmmm...actually, today!) so I'm not sure if I'll have a change to try this out, but I'm taking my n810 and the files you've provided.

stock kernel source for the module (up to 2.6.27) doesn't have a definition

Anyway, I'll try what you've generously built, but I suspect it won't
recognize the MTK-chipset GPS... Hopefully I'm wrong.

This is something I wanted to do when traveling, e.g. on a bicycle tour. It looks like a complicated and risky install (how many people have tried Jalimo?), but I'd love to know how it goes for someone else.
I have the Qstarz BT1000p, which should be able to connect by Bluetooth, but I'd be equally happy to connect by USB (I've done the hosting thing). Primarily I'd want to download and clear logs. I'd also like to be able to change the GPS settings (it would be terrible if something didn't work at the start of a trip and you couldn't correct it!), but since it seems that all of BT747 runs, I guess that's no problem.
Great stuff -- many thanks to Koios! To qwerty12, TA-t3, and z2n -- have you tried this out?

In the meantime I've found a better solution to bind the RFCOMM device
to the GPS logger. Instead of using the rfcomm command from
the bluez-utils-test package you can use the D-BUS interface to the
Bluetooth connection daemon! This means that you don't need root
permissions and haven't to install an additional package on your
N8x0! I was inspired by this post
http://lists.maemo.org/pipermail/mae...er/030367.html
but have improved the script to save the returned device name.
Now I use the following script to read out the data from my GPS logger:
Furthermore I've noticed that the Bluetooth connection with the
BT747 program drops while downloading the GPS data if you have
more than a few hundred track points stored in your device!
I think it's not really worth to spend too much time and efforts to get
this up and running, gpsbabel is IMHO the best choice to download the
data. BT747 makes only sense if you really want to adjust some settings.
I use BT747 now only to convert the raw binary file from gpsbabel
into the GPX format because gpsbabel can only convert tracks but no
waypoints!! (the M-241 logger records a waypoint while logging by
pressing the Enter button in the lat/long view)

if [ $? != 0 ]; then
BTdevice=$(echo ${BTdevice} | cut -d ' ' -f 8-)
else
BTdevice=$(echo ${BTdevice} | cut -d ' ' -f 7- | tr -d \")
fi

Koios,
Thanks for figuring this all out. I've been trying to come up with a way to get the logs off my Holux M-1000C. Do you think this would work? The program that came with the unit is for both the M-1000C and the M-241, so I'm guessing they're similar. The M-1000C isn't listed as supported on the gpsbabel site.
Thanks!

Regarding BT747 on maemo: good to see that it works (even slowly).
The main issue for the speed there is the way the emulation of the SuperWaba VM on Java works for the GUI.
I am sure this can be made a lot faster if the GUI is adapted for Maemo and uses 'standard' GUI methods.
I started of a thread on the BT747 site but that did not really go anywhere, so I decided to sign up for an account here.
BT747 has a command line interface too, so I would suggest that somebody tries to get that running on Maemo to check out the speed of that.
Regarding Holux M-1000C vs M-241. Holux managed to make changes again to their protocol and binary log format. They are similar, but not the same!
Most commands will work though and as a user you would not notice a lot. Holux's program detects the device it is talking to and adapts according to it.
BT747 has support for the decoding of the M-1000C logs and adjustments are being made to take into account the new protocol but as the old protocol is mostly in place, that is not important
Regarding the download problems with BT747: did you try to adjust the chunk size, read ahead, .... These parameters influence performance on Maemo.
Further, if there is a better connection method on Maemo, that can be taken into account.
Of course, the best thing would be that somebody with a Maemo device looks into that in detail.

I filled in the BT address as copied from Maemo mapper (I'm sure it appears other places too), and did
sh read_log.sh
in a command window. Is that the right way to run the script? You indicated one didn't need to be root; certainly I'm not root, and while I've been root, I don't remember how to become root. I had some trouble with ctrl-M line ends when I copied the files from my PC, but in read_log.sh I edited them out, and for gpsbabel I tried the version copied from my PC and a version unzipped on the tablet itself.
Would love to get this working in the next day or so! Wouldn't mind getting BT747 working too, wired or BT, but I'm not willing to risk the tablet's stability now -- no new Java install, methinks.
Thanks,
luxelux

I have been using mtkbabel with bt747 logger, just to download and clear logs. It needed couple of perl modules to tablet as described in first post. You can make it work through bluetooth with rfcomm, that is the way I normally use it. If I remember correcly it worked ok with USB cable, too.

The device also does data logging. I'm looking for a way to transfer the binary log files from the GPS receiver to my N810 via Bluetooth.
I don't expect to convert the log files to other formats or do photo-geotagging or other operations on my N810, but I want to store the log files so that they can be processed on a PC at a later time.
There are several programs that talk with the QT-1300, but they all have difficulties on the N810. Some of the issues are:
