Strange Compass/Xport behaviour

**Mad Ad** · 07-11-2005, 08:38 PM

Why is it that when I close down and restart, or reboot the PC that compass/xport doesnt work again untill I open and close the compass config page??

Nothing is passed through untill i do this, from there everything works fine again.

I can replicate this time and time again - hibernate no problems, comes back all fully working but reboot or shut off and restart, nada, no output, not untill i simply open and close the compass cfg page, then all the devices on the mapped ports can work.

I can even see it on xport- no dot over com64 until the mandatory open and close is performed, as soon as thats done, up comes the dot on com64 and then I can run stuff. Ive tried other ports, no change.

Via M10k, non-hacked XP pro, bu303.

Any ideas please anyone?

Thanks a lot

Oh that's odd! I know Xport is available before Compass starts, but if the GPS isn't ready yet it may not open either port, but it should retry every few seconds. There must be something missing there. One thing you could try is disable the auto-start and make a shortcut to it and put that shortcut in the Startup menu. That would make it start a little later.

Hi Curiosity, thanks for the reply.

Just been testing what you said and no change. Running from the startup folder (without autostart checked) still needs an open-close to begin the passthru process.

Specifically its the close event that does it. eg I reboot with compass loaded (via startup or autostart) then run an app that uses an output port, nothing happens when I open compass cfg but as soon as I close the cfg page, com64 light comes on and then the light comes on com4 or 5 and the app starts to get the gps feed normally. Makes no difference which app I run.

Setup
com3 is the gps, set in compass
com64 is the link to xport
com4 navigator output
com5 gatsohunter output

Im not running any logs or hiding the cursor or anything else, just autostart is checked.

Oddly enough, if I reboot without it loading on boot and then click on compass manually, it works straight away without open-close cfg (even if the gps mouse is not locked on any sats) .... just refuses to work from autostart or the startup folder.

Thanks a lot for looking into this, if theres any more data or anything you need id be pleased to help.

I think I've got a fix for it. Download compass again and try it out. One question though: Did you notice any info on compass while it wasn't connected to XPort? That would tell me which side wasn't working right.

Tried new version, no change.

Yes there is info, the systems on my bench so theres no speed or direction data but it spins the wheel once and registers the altitude figure as soon as it boots up.

Here, they say a picture is worth a thousand words, heres an avi of it, excuse the bad autofocussing

That's definitely convincing video. It can't connect to XPort right at startup. Could be something in XPort, but not sure yet. I have one more idea with Compass for you to try. After that, I don't know. So anyway, download Compass again and give it a shot.

I have a exactly the same problem although I have the latest version (prior to post #4). Instead of cold/re boot, the problem I have was coming out from hibernate.
The same Xport/Compass version is running fine without a single problem in my Supra setup. In my Matrix, it only work 95% of the time out of hibernation. Open and Close Compass configure window brings it back to life. Consider 5 out of a 100 times I have to do it, I wouldn't bother checking to see problem with setup or the software.

Nope, theres no change again - I am getting it from here yeah?

I've nothing else loading on startup, except zone alarm and ive tried it with that disabled. Im on XP Pro SP2 (OEM version), nothing attached to physical com ports, only usb items connected are the BU303 GPS and touchscreen.

Ive just rebooted and left it sitting there- still no action after 25 minutes, still needs an open/close to run.

Ive looked through my event logs and nothing seems amis, i noticed is that on compass cfg close SSDP Discovery Service starts up... its xp default is manual and making it automatic doesnt change anything, if theres anything I can try let me know.

:edit: not yet noticed a problem in hibernation, that always seems to work

i'm trying to get this solution to work for my hibernation/standby gps resumption issues. Basically Compass connects ( can see signal data etc ), but the programs using the virtual ports refuse to see any data. Here are the steps i took.
Setup Xport2 to Input port 64, and output ports 8, 9, 10
I setup the compass to port 7 ( my gps port ).
I can now see data when i run compass
When i run hypertermail using any of the virtual ports..nothing....the appropriate radio button in xport2 does indicate its on..but nothing like that on the "input" com 64 radio box, and no nmea data from the gps device.

What else can it be?

That's the right now. I think I need help. Try this new one and see what happens. I added a few error dialogs that should pop up if it doesn't open or doesn't find the settings. All of you are doing everything right, it's just not working right at startup for some reason. It could be because of everything going on during startup or resume. All the drivers are resetting and using lots of CPU or maybe some permissions aren't set yet. Not sure.
