These issues directly relate to the PocketPC 2003 operating system and "generally" do not occur in PocketPC 2002.
Some PDA manufacturers have released ROM updates for their PDA's to correct these problems.
If you are using the Tomtom software with a bluetooth gps see the Tomtom section below.
If you are using a O2 XDA II or MDA II or Qtek 2020 or any other PDA's based on the same hardware with a Bluetooth gps then see the Bluetooth Tools section below.
When turning off the PDA and a file stored on a compact flash card open (for OziExplorerCE this means the ozf2 image file), the handle to the file is lost when the PDA is turned on again.
A work around has been added to OziExplorerCE to reopen the map image file when the error is detected.
The problem occurred - if using map images on a CF card.
The problem did not occur -
if using map images on a CF card but also have a SD card inserted in a SD card slot. (The presence of the SD card seems to make things work ok).
if using map images on a SD card.
if using map images in main memory.
When turning off the PDA with a Com port open the handle to the com port is lost.
A work around has been added to OziExplorerCE to reopen the com port when the error is detected.
The Bluetooth com port to use for connection may be Com 8 or Com 5 depending on the Make, model and ROM version of the PDA.
When using a Bluetooth GPS and the map images are on a SD or CF card
Bluetooth disconnections may be more frequent - it may somehow relate to cpu load. Seems to happen a lot more if map images are loaded from a SD card.
If the PDA is turned off and on when connected to a Bluetooth GPS the connection may no longer work
Even if disconnected and reconnected it cannot be made to work, a reset may be required.
On the iPaq 2200 and 5500 series and possibly others, if you turn off the PDA with an active Bluetooth connection the PDA will not turn on again, you must press the reset button to get the PDA working again.
ROM upgrades are available from the HP web site support pages.
Bluetooth in PocketPC 2003 will always ask for a device before connecting
(PocketPC 2002 only asks the first time and does not ask again once the devices are paired).
If you would like the PocketPC 2002 behavior there is a registry entry which can be made.
You will need a registry editor like RegEdit.
Under the registry key HKLM\Software\Widcomm\BtConfig\AutoConnect\0005 or HKLM\Software\Widcomm\BtConfig\AutoConnect\0008 ; it may be one or the other of these depending on the PDA make, model or ROM version.
Create a new DWORD value called : BtBrowserEnabled and set it to: 0
Bluetooth should now connect to a paired device without asking.
Tomtom software and Tomtom GPS drivers 2.07, 2.08 and later with a Bluetooth GPS.
If Tomtom software is installed with the version 2.07 or later GPS driver then OziExplorerCE (or any other software) will not work with the any Bluetooth GPS when using a WM2003 PDA (or at least these models - iPaq 1940, iPaq 2210 series and iPaq 3900 series (upgraded to WM2003)). It appears that when Tomtom released its version 2.07 gps driver to correct some Bluetooth problems with these PDA's it prevented all other software from accessing the Bluetooth GPS.
Version 2.06 of the GPS driver should not have this problem, it can be downloaded from here. Tomtom version 2.06 driver
Note : Remove the current TomTom driver before installing version 2.06. (This can be done from the Start Menu by selecting "Start" > "Settings" > "Remove Programs", and highlight the TomTom ~ GPS and click the Remove button).
For details, see the topic "TomTom GPS 2.09 breaks other GPS applications" in the TomTom forum on www.pocketgpsworld.com
Please note the Bluetooth tools may no longer be required for OziExplorerCE version 1.12.0 or later. OziExplorerCE has been rewritten to bypass the issues with the Bluetooth on these PDA's.
If you are using a O2 XDA II or MDA II or Qtek 2020 or any other PDA's based on the same hardware with a bluetooth gps then you will not be able to connect to the gps with OziExplorerCE, you will get ERR in the top right corner above the map. This is not a problem with OziExplorerCE it is a well known problem with these devices, their bluetooth implementation does not work properly and requires a patch.
There are some programs which do work with these devices without the patch but these are most likely using simple polling of the serial port. I can also read the serial port using polling but this is not a suitable method to use as it slows the software down considerably, an event driven reading method must be used and this is where the patch is required.
The patch (Bluetooth Tools) can be downloaded from this site.
Setup for the Bluetooth Tools
Run OziExplorerCE and in NMEA (GPS) configuration set the Serial Port Number created by the Bluetooth Tools as the Communication Port.
