Well ... I just manually made a gpx file where I wrapped a single <trkpt> with <desc> in single <trkseg> pair and included many instances of <trkseg> and mapper showed a little green doughnut (or red if you imported it as a route vs. a track) for each separate <trkseg>.

Since I don't have a GPS yet (it is enroute from the e-store :] ) I don't know if mapper will do the flite or waypoint display if you get close to any of them in order or out of order. It certainly does show them in the right spot though.

The gpx info was in the following format:

Code:
<?xml version="1.0"?>
<gpx version="1.0" creator="http://www.gnuite.com/cgi-bin/gpx.cgi"
xmlns="http://www.topografix.com/GPX/1/0">
 <trk>
  <trkseg>
    <trkpt lat="xx.xxxxx" lon="xx.xxxxx"><desc>Waypoint 1</desc></trkpt>
  </trkseg>
  <trkseg>
    <trkpt lat="xx.xxxxx" lon="xx.xxxxx"><desc>Waypoint 2</desc></trkpt>
  </trkseg>
  <trkseg>
    <trkpt lat="xx.xxxxx" lon="xx.xxxxx"><desc>Waypoint 3</desc></trkpt>
  </trkseg>
 </trk>
</gpx>

Again, this thing is awesome :D
In a future release, Maemo Mapper will support GPSD and rfcomm connections, which will allow you to gain access directly to the NMEA data. I'm not exactly sure if that is possible with the current version of Maemo Mapper, but it might be.

Penguinbait, maemo-mapper keeps a running track of where you've been. All you need to do is save it off to disk.

However, what I think you really want is the ability to record a voice note at a location using a bluetooth headset. See something interesting? Push the button on the headset and record a georeferenced note.

See, that way you can put the GPS receiver where it needs to be, leave your 770 in your pocket with the cover safely on it, and still take notes.

Oh, and flite should send its output through the bluetooth headset.

Maemo Mapper will announce your approach to those waypoints if you visit them in order (you don't have to start at the first waypoint, though).

I could implement "announce as you approach any waypoint," but that could waste a lot of CPU if there are many waypoints. Is there a desire for this kind of "arbitrary point of interest approach announcement?"

This would only be possible if Maemo changed the "disable radios when cover is on" behavior, which may or may not happen with the 2006 OS.

Still, this would be useful if the Nokia 770 is available for access (e.g. mounted to a car window), but there would still need to be a signal to Maemo Mapper for when to start recording (like one of the hardware buttons, unless you want it to record everything you say).

NMEA output
 
Thanks RussNelson, but what I really want is the NMEA output, I wrote some scripts to plot real time as I drive and they played nicely with gpsdrive but it chewed cpu, the information is sent via bt to my webserver where it displays a map from a few different locations. I use speed, elevation, heading, so I need all the output not just location.

I really want to run this with maemo-mapper, I look forward to the future.

I loved my 770 and gpsdrive was useable, Maemo Mapper is the best software written for the 770, I do a lot of driving to different places, I can download routes from t-mobile and recalc works great. Its really a whole new reason to buy a 770, this has been a great success, CONGRATULATIONS!!! :D :D

Oh, and I have my iblue mounted high on my drivers side window, I can still roll the window down about 5 inches ;)

I have not the slightest clue after all the reading I did...on how to use this program. I don't know if it's because of legal issues that people aren't comming outright and posting the way to really use it. If that's the case, someone please feel free to PM me, or IM me at RabeeRaven on aim, to tell me what I should do map wise.

Tracking Stops
 
Hi,

Maemo mapper is easily the most impressive 770 app I've tried yet. I was leaning towards eBaying the device until I tried maemo mapper. Definitly the killer app for me an I was happy to make a small donation.

Sucking up done...

I'm planning a long trip that I've setup a route for and have been testing the app over the last few trips to work to gain confidence. I've noticed s few times now that the tracking sometimes just stops.

Observing the GPS lights show that theres a fix and that bluetooth is still active, but Maemo mapper has stopped plotting. The app is still response, restarting it results in the track still not plotting. Restarting the 770 cures the problem without restarting the GPS.

Has anyone else seen the same kind of problem? I've read through the thread but dont see the same issue mentioned.

This is using the patched version with the atof fix in and with the latest released firmware.

Dave

Read the second post in this thread if you're looking for a URI Format to use.

If it's something else, then I'm sorry that there is no formal documentation yet. The project is young. What specifically do you need help with?

Yup. I think it's been reported here before. Look at this posting:
