Posted: Sat Oct 23, 2004 11:22 am Post subject: TomTom3 Bluetooth - GPS position unreliable |
|
|
Morning all...
In the interests of license preservation (or at least that's how I justified it) I bought an iPAQ rx3715 & TomTom 3 Bluetooth Kit with the intention of adding the speed camera database to it. Before I even get to that step, I'm having problems getting the Bluetooth GPS working. I can use the bluetooth manager to connect to the GPS, and I've configured TT3 to recognise the GPS (I think by setting the port to Bluetooth Serial Port Com8, which gives me a 'GPS position unreliable' message in Navigator.
TomTom GPS dosen't show a signal whether the bluetooth connetion is connected or not.
While the maps are very good, I can't get it to find my street while trying to navigate a route. Surely expecting to be able to navigate to any given road without knowing the postcode isn't unreasonable?
Anyway, for anyone on here that may have TT3 BT, if you've experienced similar problems, any help would be much appreciated... |

Firstly, it may not be COM8 - TomTom GPS drivers are known to redirect COM ports. Try uninstallng the current GPS driver and reinstall v2.07 from our downloads page
Secondly, "Is my house on the map?" is a very valid question, but more often than not programs fail to answer affirmative because the map material is flawed. Maps are never 100% complete, which immediately means your house (or your street) may or may not be on the map.
You can try another map provider and see if their maps are better. Mapopolis use Navtech maps, and you can download your county for free to check. (Mapopolis use NAVTEQ maps, TomTom use TeleAtlas maps.) _________________ Lutz

What may not be COM8?
Last time I put 2.0.7 on, it made my iPAQ crash and finished up with the only way I could get it to turn off was to take out the battery.
I've now uninstalled 3.0.3 that it came installed with and put 2.0.7 back on again. It's crashed again, but having turned back on, it will now allow me to select Bluetooth Serial Port COM6, which I've selected. Which port should I be using?
What should the LEDs on the GPS be doing?
I can find my street on the map by using the Postcode POI database but not navigate to it by street name in TT3. |

The COM port you should be using. On your Pocket PC, go to the BT settings > Services > Serial Port > Advanced and note the Outbound COM port. That's what you should be using. It differs from Pocket PC to Pocket PC. On my 6315 it's COM7 _________________ Lutz

I've tried installing 2.0.7 and it made my iPAQ crash. Wouldn't turn back on again until I put it back in it's cradle & it reset to factory settings.
Any other ideas? Thanks again

after a factory reset you should be able to access the GPS receiver directly from a utility like WinFast. Can you try that before you install any of the TomTom stuff? _________________ Lutz

What is WinFast? Is that a native or 3rd Party package? How do I manually initiate a factory reset? |

You can get Winfast from our downloads page.
To hard reset, press and hold 2 outer buttons and at the same time push the reset button with the tip of the stylus. be aware that this completely wipes all data and programs that are not stored in the iPAQ File Store _________________ Lutz

Where is the reset button? I tried pressing the button on the 5-way controller in conjunction with the 2 outer buttons & it sent the screen into landscape mode, which was a useful shortcut. |

the reset button is on the bottom of the device, near the iPAQ Mobile Media button. _________________ Lutz

I had a similar problem while testing an iPAQ 4700 WLAN the other day. The symptoms were that I could find the GPS receiver using Bluetooth Manager, but I never actually receive data from it, either in TomTom Navigator or in the standalone TrafCam program. I knew it wasn't hardware because the same GPS would function perfectly well with a Pocket Loox 420 I was testing at the same time.
I mentioned it to globalpositioningsystems.co.uk, who had lent me the unit, and they pointed me to this page on their site:
http://www.globalpositioningsystems.co.uk/page.php?page_id=7
After I downloaded the fix for the 4700 and did a soft reset, all was well. I notice that there is a similar 'fix' for the unit you mentioned. |

@trafcam
thanks for the links. Interestingly enough they all do the same - replace the TomTom BT driver back with the original.
You can achieve the same goal by either using a registry editor and in the branch
HKLM\Drivers\BuiltIn\Serialx (x being your outbound serial port)
setting the string value "DLL" back to its original "BtCeIf.dll"
OR
BY NOT INSTALLING TTGPS 2.08 or later in the first place... _________________ Lutz

How do you soft reset? Is this the same as just turning the device off and on again via the power button?
Charlie over at the GPS forums pointed that out to me as well, but it didn't make any difference. |

To soft reset you have to poke the stylus into the reset hole at the bottom or side of your PDA. It is not the same as switching the device off and on. It's more equivalent to the rebooting of a PC. (whereas the switch off/on is more equivalent to standby/wakeup)
If you do not know what a soft reset is then you are a very lucky man. Most Pocket PCs require a soft reset at least once a day. _________________ Lutz

I had this problem when i first installed TT3.
I installed it onto the SD Card along with the maps.
Once I reinstalled it onto the main memory and just had the maps on the SD card, everything has been fine since.
POIs all showing, IR beam on - and I never get a freeze up. _________________ Garmin Edge 800 (cycling)
