Multiple bluetooth device communication question

I am new for bluetooth technology. I want to know is it possible to
use one one integrated bluetooth pocket pc (like ipaq) to communicate
with one bluetooth enabled mobile phone for web browsering and connect
to a bluetooth GPS for location data at the same time?

Based on what you said, I only need to make sure the PDA CF card can
support multi-connection function (I am working on a pocket PC
application and trying to connect two bluetooth enabled devices -
cellular modem and GPS at same time), whether cellular phone or GPS
device support multi-connection really DOES NOT MATTER, is that right?

So how do I know which bluetooth provider has implemented this
feature? I am interesting in PDA CF card, something from BELKIN ,
SOCKET COMMUNICATIONS
or AMBICOM.

Thanks

Completely possible. I do it all the time. Although part of the phones don't
implement this, handling multiple connections is a part of the Bluetooth
Standard.

It is right as long as you are using different com: ports for each exit. You
will not be able to dial a phone call while using GPRS, this will usually
stop gprs for the time that you are talking. But as long as the ports are
different (Bluetooth_Phone and GPS, or such), there will be no problem at
all.

Surely it depends on the drivers. But all branded cards that I know work
like this.

Just another related question here ! Has someone tried this :
1. Take 3 or more bluetooth enabled devices and pair each one with each
other.
2. Space them so that each one can only see its neighbors (in a strait line)
more or less 7m-8m apart.
Like this : Device1Device2Device3 . . .etc.
3. Now try to send a file between the 2 furthest apart .(I am using 4
devices therefore the distance in my case is about 30m!)
Are you surprised ! ! ! Well I could not believe it neither ! Can some one
explain how is this possible ? ? ?
Greetings from SA

Scatternet... This is one of the functions of Bluetooth. If you have paired
devices and they're all visible to each other, the network can expand and
reach the size of the area covered by all devices.

This is still rulled by the 10m or 100m limits in both devices. in each
individual section covered, of course.
