Anton:

These ARE somewhat pricey, but they are Class 1 Bluetooth, which has 
enormous range: we routinely get 50 meters INDOORS with two Class 1 
devices.  In fact, I can remove the antenna and stick it in a steel 
filing cabinet and still get a good signal.

In any case, another alternative that we are starting to explore is 
www.blueradios.com which are also Class 1 devices and go down to $35 at 
100 pcs.  We just got the eval kit - if you ask again in a few weeks, i 
can let you know how things are going.

In our case, we require Class 1, and we've not seen any cheaper options.

Thanks,

I had a look and they definately would do the job. The price I
feel might be a bit high. For the same price one can buy a GSM
module with GPRS. Wasn't  bluetooth supposed to be a lot cheaper ?
Is US$80 for a bluetooth module about average ? For the application
I have in mind I need a price of below US$40 for low quantities.

Yes, we're chatting happily with a Linksys USB dongle; I believe that 
we've had multiple simultaneous promi<->dongle conversations, but can't 
swear to it.  In principal, it shouldn't be a problem.

Have you used this to communicate with a USB/Bluetooth dongle on a PC?

On their webpage, they talk of point-to-point comm; do you know if multiple
such units can talk "simultaneously" to a single bluetooth dongle?

Sorry if these might be stupid questions - I'm new to Bluetooth.

We've used it with superb results.

Hi,

I'm an embedded developer, but never worked on any Bluetooth stuff before.

Does anyone have any good links so I can do some reading up?

I am wondering what hw/sw would be involved in a Bluetooth hands free kit
for a mobile ( cell ) phone? Like the little Bluetooth head-sets you can buy
for $40 or so?? Do people offer off the shelf modules for this?

Thanks,
David.

Has anyone ever actually seen a Zensys product?  They were talking smack 
about some badass low-bitrate wireless meshing module based off an 8051 
some time ago.  Aimed for home automation and what not.  It looked 
pretty cool, but I havent seen or heard from them in a long long time.

They're not purchasable, are they?

Parallax is selling one.  Go to their web site (www.parallax.com I
think) and search the catalog for Bluetooth.  I've used them to
communicate between a data acquisiton module based around a PIC 16F
and a PC with a Linksys Bluetooth to USB widget.  Worked very well.
