Bluetooth problems with Holux 240 GPS BT Serial

[hlouie]

Current Setup
1. Hard-SPL-240-MFG.exe
2. titan_radio_3.27.00.exe
3. dcd_titan_kitchen_2.3.2.rar

Everthing works with some data issues when downloading large files due to a but in the titan_radio_3.27.00.exe (I can live with it).

The problem is when I partnership the Titan with the Holux 240 GPS external Bluetooth GPS it does not connect. I can see the device but never can connect, Yes I use the standard 0000 passcode. Other Bluetooth devices ie my headset Moto N700 and car head unit Sony BT-2500, audio and hands free all work. I'll be travelling to an area with no Digital service and would like to use the GPS with Navigation software.

When I restore the original TELCOM ROM, I have no problems with Holux 240, Moto N700 and Sony BT-2500. When I connect I see a serial port as a list service.

Some threads talk about a fix for the Bluetooth stack? nueROM or Dogguy in PPCGeek.

Another item to be noted. With Bluethooth A2DP headsets, if I connect once do I have the reconnect to the device again? The Sony BT-2500 pairs with with Titan (any CE ROM) but I need to resave the audio everytime.

I thought the GPS chip in the Titan was a gpsOne that uses digital cellular signal from the towers to triangulates your position.

From phonenews.com
Installing this update will enable GPS to function inside your HTC Titan. It enables the gpsOne chipset in your device to function as a standard GPS device, compatible with Windows Mobile 5 & 6 GPS applications, including Google Maps, Windows Live for Mobile, and navigation software such as TomTom Navigator. Keep in mind that gpsOne is not autonomous GPS, you will need to have home network coverage in order to maintain a GPS lock.

Found some more information

gpsOne can operate in 4 modes:

Standalone - Your handset has no connection to the network, and uses only the GPS satellite signals it can currently receive to try and establish a location.
MS Based - Your handset is connected to the network, and uses the GPS signals + a location signal from the network.
MS Assisted - Your handset is connected to the network, uses GPS signals + a location signal then relays its 'fix' to the server, which then uses the signal strength from your phone to the network towers to further plot your position. You can still maintain voice communication in this scenario, but not 'Internet/Network service' ie Web Browser, IM, streaming TV etc..
MS Assisted/Hybrid - Same as above, but network functionality remains. Normally only in areas with exceptional coverage.
