I have the above setup (Toshiba  e830w with built-in WiFi and Bluetooth
+ Globalsat BT-338 bluetooth GPS receiver. I am unable to extablish a
stable connection between these two devices. While e830 discovers
BT-338 and I can register a connection and assign the device to the com
port 6, the connection status is always disconnected and satellite link
test program that comes with BT-338 sees no GPS signal. Neither
Destinator navigation software sees GPS signal. Said that I had few
glimpses of success - within 4-hour tests and trials I established GPS
link 3 times and the location shown on the screen was perfectly
correct. Each time the link was established it was lost within a second
and navigation software got no location update if I kept moving around
the streets.

I have tested e830 bluetooth feature successfully with my mobile phone
(sony ericsson T630). It works flawlessly, allowing me to establiesh
stable connection, download email and browse the Internet.

I have also tested BT-338 with another bluetooth PDA (HP h4150) with
the same BT-338 test utility and navigation software and it worked
flawlessly as well.

So there is no doubt that bluetooth features on both devices are
functional and the problem is with either some settings or general
bluetooth stack incompatibility.

Any suggestion on how to fix it would be greatly appreciated.
