Skytraq module. Was:: backlog of gpsbabel patches

Well, now I know why I thought Skytraq was in; it was becuase it sounded familiar.

It looks like two or three people independently developed a module for this device around the same time and submitted them.  (I don't see a patch from
Jesper in the archives.)   Each of them had strengths and weakness (hardware variations supported, GPSBabel integration, OS/portability, etc.) and a number of lengthy and active discussions ensued, but always seemed to end with "but what about..."

So I knew we'd burned a lot of programmer time on it arguing about bits and bytes, so it sounded familiar.   But now that I look back at the mail archives, I think I see what happened.

There wasn't a clear "winner" that was obvious enough for me to be the Chosen One and submit it.   (Mathias, Jean-Christophe, Martin, and others involved are free to set my Bozo Bit at this point, tell me I'm a doofus, and send me a "final" version before mocking my competence as the Chief Babelhead.)    So I never actually commited any of them.

If there's a consensus on one set of patchs that contains the best of all the things we discussed, I'll get it integrated.   It just seems to have sort of coasted to a halt as I had the impression that all the threads discussing it still had open issues.

Guys, can you tell me where we are with Skytraq?     I'd much rather have three guys working on one patch than three guys with three patches.  


Additionally, there are two other largish I've been neglecting, too.
1) Support for the Delorme PN series.   (Needs OS work.)
2) A new GUI, written in Qt so we can finally have the *same* GUI on all OSes has been contributed, but I haven't added it and worked through the build issues.  (Needs to be packaged sensibly as it'll be large.)

Hi Robert,

Just read your comment on working through the backlog of gosbabel patches.

Any chance for the patch for Skytraq Venus 6 (and also 5) GPS devices from Jesper Zedlitz?
I think he submitted in Autumn 2008.

Anyway you can read all about the patch here:
http://www.zedlitz.de/skytraq/

and more details here:
http://code.google.com/p/skytraq-datalogger/

Thanks,
Jan

AFAIR, Mathias merged the interesting stuff from my patch in his, which
he published on 2009-02-10.
I coded that because I needed to read my unit quickly, and until now I
left it in a "worksforme" state. Moreover I added stuff to setup the
unit which doesn’t have its place in Gpsbabel and wich were left out
since a standalone app exists for that purpose.

I think you can leave me out as a "competitor" for now ;)

Hello Jean-Christophe,

the "standalone app", is that the Linux skytraq-dataloger from Jesper Zedlitz?
Or is there another program? Where to find it?

Yes I thought of this one. In fact I didn’t try it since my version of
Gpsbabel did the job. I took some time to do a little testing and it
appears to work for my unit. It just doesn’t report the POI count (but
that’s not really important).

Hi Robert,

from my point of view the patch from Mathias looks like a reasonable
first implementation for gpsbabel. While it did not work in all
scenarios for me, it was a solution which did at least partly work.

Generally I think it is a good idea to start adding skytraq support now,
as this might help to improve the situation. Nevertheless, I'd expect
some bug reports regarding skytraq devices.

regards,
Martin

I'm nervous that the author has gone quiet on this, but in the interest of advancing things I've committed that last patch from him.

Anyone that has the hardware or is familiar with the hardware that can address his last status items, please do:

Current TO-DOs are:
* reading problems with Venus 5(?) devices (reported by Martin Maurer)
* testcases for testo
* and last but not least, the documentation...

As it looks like this strictly a protocol-based implementation, I don't knw what the plans were for automating testing via testo, but we definitely need a couple of paragraphs from someone that knows the hardware and lists models that work with it, care and feeding tips, etc.

Thanx,
RJL

Hello Robert,

sorry, I didn't have much time to work on this lately. Just saw the
topic popping up on the list again, so now I'll take the time to
complete the last steps to finally get it into a usable state.

I remember having written some doc but apparently never posted it here.
I'm going to complete it and then post it here in the next couple of days.

I remember someone pointing out that other protocol-based formats use
raw binary data as reference input. This way the data conversion can be
validated at the least.

For debugging/protocol sniffing purposes I created a perl script which
emulates a skytraq logger device on a unix socket file. I didn't look at
testo yet - would it be possible/worthwhile to use that script for
validating the transfer protocol implementation? However I'm not sure
whether this works outside the Unix world...

Excellent.  Glad to know you haven't left us. :-)   I can certainly relate to the busy thing - it was my own busy thing that lead to this being dropped the first time around.

I remember someone pointing out that other protocol-based formats use raw binary data as reference input. This way the data conversion can be validated at the least.

Some do.   For the logger products that are basically block level devices "I'm going to send you a packet, blast 450K of crap to me that I then have to pick apart" that works reasonably well without tormenting the code too much.  For devices that have a more conversational/interactive model, it works less well.  (Yes, I know it can be made to work.  We've just traditionally not done so.)

 
For debugging/protocol sniffing purposes I created a perl script which emulates a skytraq logger device on a unix socket file. I didn't look at testo yet - would it be possible/worthwhile to use that script for validating the transfer protocol implementation? However I'm not sure whether this works outside the Unix world...

That's an interesting approach.

I'm fine letting the test suite be your call.  If you think it's exercised well enough on the OSes that matter and/or that there's enough debugging tools in there that we can figure out where things are jumping the track if they do fail, I'm OK skipping it.   (Just look at how many Garmin protocol problems I've solved through the history of this project from hex dumps.  It's a hard life.)

Thanx,

I would suspect that the "perl approach" creates a build-time
dependency on perl. For people who have an operating system that
doesn't include perl by default this may not be easy to comply with....

Hi,

attached the xml doc file xmldoc/formats/skytraq.xml.

Please consider it as a first draft, comments welcome. Especially as
English isn't my native language...

Is there a way to include the additional descriptions for the options
into their categories (which are created automatically from the source
code)?

btw: I just checked out from CVS, and reading my logger did work with
that version :-)

However, make doc aborted on xmldoc/formats/garmin_gpi.xml so I used the
old one instead. Didn't examine it further though.

<para>If available, reading the logger using bluetooth should also work. However, many devices support only one
specific baud rate over bluetooth, e.g. 9600:</para>

</example>

<para>The "initbaud" option might be helpful if autodetection fails or takes too long. With this option you
can tell gpsbabel the baud-rate the device is currently set to. In contrast, the option "baud" specifies
at which rate the actual download should take place. If it is different to "initbaud" (or the autodetected
rate, if initbaud wasn't given), the initial setting will be restored after finishing the download.</para>

<para>If read-at-once >= 1, batch mode is enabled with that many sectors being read at a time.
Under normal circumstances, the larger this number the faster the transfer.
Reducing "read-at-once" might help when you get transmission errors/aborts.
This option only applies to Venus 6 devices, Venus 5 devices always use read-at-once = 0.</para>

Thanx.  I've applied that.

No problem.  Your English is better than my German.    (And,
embarrassingly, better than many native speakers of English. :-)

If we create an xmldoc/options/skytraq-OPTIONNAME.xml, that'll get
injected into the doc as a more verbose format.

We have tools that check for such default doc and warn about them, but
I have to confess I'm pretty far behind in tending to such matters.

Regenerating all the doc changes since our last release (in October,
sigh) for review is in my top-ten list of things to make happen....

Yay.

Someone else complained about that.   As we've made no progress info
finding that that link fails for some people and our resident Docbook
dudes have offered no hints, perhaps we should just tweak that to not
use the anchor tag to sidestep that.

Thanx,
RJL

Hi,
Anyone has any news on the release of a Skytraq module for GPSBabel? I saw a patch on http://www.zedlitz.de/skytraq/ but can't find a way to compile it on Windows...
If no date is planned yet, maybe someone has another solution to extract NMEA sentences of a Skytraq Datalogger in command line on Windows (and not through GPS Photo Tagger).
Thanks a lot.

Laurent

I'm actively working on getting a beta up for all our OSes.   I'm traveling next week which doesn't help, but it's my goal to have a beta out this month.
