One dongle, different PCs... pairing problem?

Hi
I have the same problem moving the Belkin dongle from PC to laptop the
phone a T68i still sees the PC, also I accidentally changed the name
of the phone then changed it back now nothing I do will make the
laptop see the phones current name. It's almost as if the info is
written to the dongle's memory.
As I write this I can't get them to pair at all. I may give up...

Incidentally I have an iPAQ, which also sees the laptop as the PC via
the Belkin dongle.

It would be interesting to know what dongle "Neevok" bought and if it
worked any better.

They warned me about BT being new technology...

They link key generated during the pairing procedure
is not stored on the dongle's internal storge.

Usually, the Bluetooth stack running on the PC stores
either in a file or in the registry. So, if you
move the dongle among several devices, you will have
to reinitiate the pairing all over again.

I don't know which software stack you are using
on the PC side, atleast I know that the MS stack
stores the key in the registry.

Hope this helps.

Thank you, that's pretty much what I figured. I did find the
generated key in the registry on my XP box; not sure where to look on the
iMac, though. I'll try to propagate the key around
and see if that keeps pairing easier. Thanks!

I have two MSI USB-Bluetooth transceivers. (100-200m) One for my laptop, and
one for my desktop. My bluetooth network also consists of my Ericsson T39m
mobile phone (10m), which is recognised by both pc's for connecting to the
internet and synchronising files etc..
On my laptop (through bluetooth) I also use the 56k modem which is connected
to my desktop via a serial cable.
cheers Neevok

The other thing to understand is that the bluetooth device is recognized by
its pairing partner by is MAC address - so if you move the dongle to another
PC, the phone thinks it is talking to the same machine, but when it tries to
check the pairing information, it fails because that information is unique
to the PC.

It was never meant to be used in this way I expect; buy another dongle....

Thanks for the advice -- I had also come to that conclusion. If there
was just a way to ENTER a key, that'd make things work pretty well,
but the technology's too smart for that, I guess!

My overall reaction to Bluetooth hasn't been very good. I somehow assumed
that
it would automatically recognize and connect to devices; yet I have to
explicitly tell my Nokia 3650 to connect to the Jabra headset every
time I want to use it. I can't use the phone as a GPRS connection to
the Internet at the same time the headset is connected. And it seems
like I'm always having to reconnect or reboot, although that may have
to do with confusion over the keys.

With the headset in particular, the lack of a wire is nice, but the ease
of use of the wired headset is hard to beat.. Just plug it in when you want
to use it and unplug it when you don't, no worries about pairing, charging,
ten-keypress connection sequence, etc.

On the other hand, if you avoid Nokia's desktop software, it's pretty easy
to transfer items in and out of the phone.

I hope they get the user experience stuff ironed out soon. It still
really has the air of a hobbyist technology.

Thanks again!
