Can a single Bluetooth GPS receiver "talk to" two independent Bluetooth
capable devices at the same time?
My wife and I both have Treo 650s and I just bought a Globalsat BT 338
receiver. I haven't tried the experiment yet, and BT is so mysterious
to me that I can't figure out whether or not this should work. Anybody
know?
Don't quote me on it but I think that www.gpsgate.com can "re-broadcast" the
gps info. Ask the developers.

As far as I am aware you cannot do this. GPS gate is used mainly for
PDA's using more than one GPS program.

Actually I believe it is possible. I have no experience with either of
the products you mention, but technically it should be possible.
You would pair the GPS with one of the Treo's and then use GPS gate to
"split" the data to 2 serial ports... One local and one BT "outgoing"
port. You could then pair both Treos and have the second one read data
from the first.
I'm sorry if this isn't very clear, I'm not sure I'm using the correct
technical terms to explain. Please let me know if you don't understand,
I'll try to explain some other way.

Ricardo,
You are correct it did work. This is how I did it :
I am using an iPaq 5550 running 2003 and iPaq 5455 2002 both units
running GPSGate, GPS used RoyalTek 2001 SIRF III.
Unit 1 5550 activate Bluetooth, in GPSGate input COM 8 baud 57600
output Virtual Ports COM 4.
Unit 2 5455 activate Bluetooth pair 5550 and 5455 together, in
Bluetooth connect to Unit 1 (iPaq 5550) to serial port, in GPSGate
input Virtual COM 4.
Both units now receive GPS signals from the RoyalTek 2001t.

FWIW, Emtac's Trine BT GPS can supply data to multiple devices, IIRC three
max.

Darren,
Thanks, I know that but this was a test which many said could not be
done. Actually I asked the same question a couple of months ago and no
one could give me an answer. Well at least I am happy using one GPS on
2 different units not just one GPS used to split GPS signals usable in
different programs on the same unit, that was too easy.

Cool!
I'm glad I could help out :)

AFAIK a single bluetooth transmitter can only connect to one device.
However, you could connect two bluetooth transmitters to a single GPS
with one of these

and two of these

You'll need a GPS which can deliver 4800 baud NMEA data. I have one of
these PC-Mobile transmitters, and it works very nicely.

Tim,
I personally think GPSGate is a better solution, first of all it's
software not an add on box which I'll have to carry with me and
secondly GPSGate it's price is right :-)

No. The bluetooth standard allows up to 8 connections from any device. It is
the choice of the implementor of the interface whether he wants to write the
code to support that. And since time is money, most only implement a single
connection.
