[RELEASE - Public]GPSSecure - GPS Tracking

**davidhite** · 02-05-2006, 01:40 PM

Hey Brady,

Nice work on GPSSecure.

I'm running GPSSecure on my XP Home laptop. I was able to get it to update the server once only when it first started. After that the status box says "No log info to upload". It has been running for about an hour.
Logging Options are set to:
Position Logging - on
Position Log Freq - 15 sec
Attempt Server Log upload every - 15 sec
Live Position Upload Every - 5 sec.

I'm running my GPS in demo mode so it just travels a straight line north. The GPS is connected and is updating the coordinates in the GPSSecure main window.

I also noticed the GPSSecure process appears to be leaking handles. The handle count is over 5,000 and climbing after an hour.
It also throws an exception when I hit "Connect" when the com port is in use by another app.

I'm exploring technologies like GPSSecure for my Google Earth/GPS Multi-Tracking app.

Keep up the good work!

Well something is definitely up if your handle count is going that high. I let it run on my computer for 3 hours and it was still at 24.

If you turn of server log upload and let it run is the log file being added too?

...please elaborate. Do you have a link to your project? I was planning on doing this as well.

I turned off server log upload and the log file is not being added to. The main window shows "Live Tracking Status: Failed". Here's a shot of the app threads if that's any help. I attached with the debugger but couldn't tell much other than whenever I paused, every thread appeared to be stopped at the same address in ntdll (FastSystemCallRet()?).

Thanks for letting me know. The person that usually fixes it won't be around tonight but I'll have him get it back up first thing in the morning.

What debugger are you using there?

To be honest I'm not sure what is causing your problem. I've never had anyone have a problem with it getting GPS fixes but not adding them to the log file... If you turn everything off (live tracking included) does it give you any more information in the status bar (right above the live tracking status)?

I'm just using Visual Studio '03 and Sysinternals process explorer.
I don't get any more info when I turn everything off.
I'll try it on a different system.
Thanks,
