I just got a Qstarz QT-1300 GPS receiver. It pairs via bluetooth to
my N810 running Diablo. Maemo Mapper or Wayfinder can use it as an
external GPS.
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:
* The N810 does not recognize the QT-1300 when connected via USB. This
is probably due to a definition being missing in the cdc-acm kernel
device drive. I had to modify this driver for the GPS to be recognized
under Fedora 9 on my laptop.
* The BT747 program offers complete management of the GPS data logs,
but it requires Java.
* The Perl program "mtkbabel" looks like it has the potential to
run on the tablet to manage data transfers and conversion, but there
are 3 issues:
the program requires perl modules that aren't on the tablet
(File::Basename, Device::SerialPort, and Date::Format)
the Perl program assumes that the GPS is connected via a USB
(serial) cable, not bluetooth
mtkbabel has a known bug that means that the data conversion
does not work correctly on the tablet. This would not be a
big problem if the other issues were fixed and mtkbabel could
transfer the binary log files without converting them
Any suggestions for method for transferring the log files off the GPS and onto
my tablet?
Thanks,
Mark
