Question about Fujitsu Siemens Pocket Loox N520 Pocket PC

PDA now doesn't pickup GPS satellites;when it did I couldn't access map charting software

Intergral GPS is set to use COM 8 port for hardware connection and COM1 port to talk to other programs, using COM 1 and having tried several other alternatives, unable to get navigation charts to pick up GPS signal, error code: Communication Timeout.
PDA settings are NMEA 0183, Baud Rate 4800 in accordance with PDA handbook and chart software instructions. Unable to confirm COM8 was factory setting but other than that, what am I doing wrong?

    Changing the Baud rate to 57600, and several other rates tried too, hasn't resolved the problem.

    I'm guessing but I reckon it's either because I've altered the Com port settings for programme and hardware or there has been a hardware failuer of the integral gps device. Since this worked previously and I don't have much belief in concidences I am sceptical of that idea

  • pobble Jan 27, 2008

    Further observation which leads me to think the Com port settings are the culprit.



    ......Just tried to connect the charting software to the GPS locator(even though it had no satellite fix) and I get a screen warning which says" unable to open Comport ,check that no ther device is using the GPS" it thenm directs me to the IR setting which shares the same Com port-- the ' all beam accept' check box is empty and I have no other software using the gps, so even more puzzled.



    Therre are clearly two issues here.



    1. what has changed to cause the GPS locator to fail

    2. What must I do to the settings for the charting software, to let it connect to the received gps signal

  • pobble Jan 27, 2008

    Well done!

    tried Com ports 1:4- no good
    also 4:1- also no good
    BUT returned to Com port 1 for gps hardware and back to Com 8 for interface THEN did your suggested 'soft' reset.

    The GPS locator immediately showed satellites it was trying to lock on to- I suspect this hardware is very basic as it showed only three weak signall stats. whereas my handheld Garmin, alongside it shows 8 very strong signals- so this device may never be satisfactory- but at least it is working.

    However, issue #2 - of connecting the mapping software continues to be a problem.

    If I switch the locator off, then activate the chartware( the pda has only a small amount of RAM) I get " communication timeout.

    If I leave the locator on,in the background, the same message comes up.

    In both cases when I check the Settings from the main Windows Mobile screen, I find that there is a message on the GPS menu screen telling me that the Com port can't be opened and to check if another device is using- which is not the case.
    The chart software setup drop-down menu also tells me that a 'communication timeout' has occurred(with gps locator running or off). Also I get a message that 'Com port #' unable to open"0

    By the way my pda has SiRF device and I've tried altering the setting from NMEA to SiRF without success

    Since resetting and recovering the gps locator, as above, I've tried the earlier suggestion of a 57600 Baud rate but no good.

    The

  • pobble Jan 27, 2008

    No facility to do so, so far as I can tell, and Com 1 is for the now working gps hardware, so expect you meant Com8 but the same applies

  • pobble Jan 27, 2008

    Yes, I reckon you are correct in your suspicions but I have checked out, or so I think, those elements you mention and I cannot see any conflicts.

    No other software is using the same Com port as far as I can see, at least in gps terms. No other application is open at the same time as the mapping software/gps locator- so I think I'm at the fullest extent of my competence- which isn't saying much!

    I shall make renewed efforts in the week ahead and try any other ideas that come to mind and if, by some chance, I find a solution I shall so inform you.

    May I take the opportunity now, in case my return is not worthwhile, to thank you for efforts- I am much obliged.

    Best wishes

    I'm unable to identify a manual port on either the pda or the charting software, so maybe that isn't an option on this device?

  • pobble Feb 02, 2008

    Yes, it is impressively short on technical stuff, including setup, defaults settings etc !

Set Baud to 57600

Posted on Jan 27, 2008

  • Rishi Roshan Ali Jan 27, 2008

    did you try resetting it ?



    if that did not help try setting your gps to com 1 and the iunterfce to com 4

    or vice versa

  • Rishi Roshan Ali Jan 27, 2008

    the mapping software



    check your settings in the mapping software

    see if your settings seletcted com port is set the the same comports you have set..



    also look at your different connectivity options,, LIKE infered , blue tooth etc. and make sure it isnt the same com port that your mapping software needs to be used, you can try disabling differerent connection types ..



    But basically what is happeneing is that the port the app is set to, isnt open or is being used by something else..



    Try those and let me know what happens

SOURCE: Communication Timeout

Under connection settings switch off the "beam" - apparently there is a conflict between the IR beam port and one of the ports used by the GPS system. Has worked for me.

NEED UPDATES


Yes, you can get SOME updates for free... indefinetely.

You will need the latest version of TomTom Home software, available for free from www.tomtom.com.

Install the software on your computer BEFORE connecting the TomTom GPC to the USB port of the computer.

The free updates you can get are:

1) "QuickFix" updates. This contains the global positions of GPS satellites, allowing the TomTom GPS to get a faster lock on the GPS satellites (the GPS will get a lock within 5-10 seconds of being turned on, instead of 2-5 minutes on some other GPS brands). It is suggested that you update the QuickFix at least once a week. If you don't do it often, the GPS will just take longer to find the GPS satellites, that's all.

2) Minor updates to your map(s), but only the ones submitted by other TomTom users.

3) Updates to POIs (Points of Interest), such as new stores, malls, gas stations, parking lots, etc.

Whole-map updates ARE NOT FREE

Webupdater won't detect Garmin unit


The below solution that I found on another site worked for me. Good luck!

Look at the programs you have running in the background. Some of those like printers or PDA interface software will hog the COM1/Serial port. I just looked at my task bar on the bottom right of the screen, and right click and turned off my printer software and a few other things. Then my GPS would link up properly and update with the Garmin Updater. I don't get why all the other forums have complicated explination that only help a small precentage. This solution will help over half of the problems.

S620 Using GPS with Memory Map software


In the Comm Manager, select Settings, then Bluetooth.  Again select bluetooth and then scroll down to your GPS receiver assuming you're paired correctly.  Click Menu and then COM ports.  Now click Menu and select New Outgoing Port.  Pick COM6 assuming you have nothing else on this as your outgoing port.                   Now go back to your map program.  In the GPS settings, select COM6 as your GPS and it should now give your position.  I use google maps and have no bother.

NMEA communication does not work ( but file transfer is OK)


Try rebooting windows, with gps off connect the cable to gps.

Go out side get a good gps signals on nav menu.

Set the gps communications menu to , nmea, 2.1

Plug the device into a good usb port.

If you look under modems, in control panel you should see a new modem called explorist xxx

If you look at the properties for that you can see its com port number.

I just tried this program http://www.visualgps.net/VisualGPS/

and it views nmea from the explorist, just set the com port to the one in the explorist modem .

E570 with GPS and Navi


Personally I have not GPS on my PDA but there is no reason that it should not work properly. The only thing is that you should pay attention on several things. Check by software producer if the software is compatible to your PDA. Please also be careful which ports use GPS hardware because your PDA has no USB port just serial port. With another words check all this important things before you buy anything.
