'[PICLIST] what is bluetooth?'

Hello picsters!

I was wondering, exactly what is bluetooth?

Is it a protocal and an rf tx/rx system??

or more or less?

Has anyone done anything with it using
a stamp??

I'm working on a basic rf remote control
device and so far it's a real pain.  Is bluetooth
low level enough for something like this ?
Or would this be putting out a match with
a fire hose??

Thanks all...

part 1 2084 bytes content-type:text/plain; charset=us-asciiDon't know much about Bluetooth, but from what I've seen it is targeted to high
speed communication.

If you want something simple... look at the Linx modules or the RF Monolithics
single chip solutions.  You'll need to conjour up your own serial communication
protocol, but that's the fun part.  I'd recommend a differential Manchester
encoding.. I tried just a straight forward 1/0 scheme but duty cycle distortion
and stuff like that caused more headaches than it is worth.  Differential
Manchester is one method to keep it synchronized on a bit by bit basis.

Go to http://www.bluetooth.com

It is mainly designed for short distance (<10m) data and voice. Cable
replacement ideally.

2.4GHz. Chipsets only just becoming available, around $10 per end.

In many wys, it is the next generation of DECT.

If you want to develop a bluetooth product, expect to get into $100K
expenses simply for qualification/certification.

More like putting out a match with a small lake methinks.

Bluetooth is a wireless protocol that is good for "about" 30
feet typical. I would recommend checking out http://www.bluetooth.org
or http://www.bluetooth.com . The .com is for more general info while
the .org is for "SIG" members. At the .com site you can download the
Bluetooth specifications. Bluetooth is in the frequency of 2.45GHz
industrial-scientific-medical (ISM) band. There are alot of companies that
manufacture or are in the process of manufacturing Bluetooth devices.

National ( http://www.nsc.com )
ATMEL ( http://www.atmel.com )
RF Micro Devices ( http://www.rfmd.com )
Philips ( http://www.philips.com )

And the list goes on and on!!!

I don't know enough about the stamp to comment on it's use I'm afraid.

Best of luck!!!

as far as i rememebr.. its the name of a whale :-)

its like aloha.. coupled with the concept of HAM radio networks..
if i want to establish a session from A to B i do so by using some
intermediate guys at a shorter distance to do the same..

If you want to do something really basic, and you just the radio mechanism
to establish a connection but you do not want to be fully Bluetooth
compliant then this is feasible.

Using something like an ericsson module will fit your requirements, see
mobile.ericsson.se/bluetooth

SW.

(I realise you know this Scott, but the original poster probably doesn't)

Can't remember the exact reference but somewhere in the Bluetooth
documentation they spell out the licence agreement.

About the only thing they will sue you for is trying to use the
technology/protocol *without* getting the product qualified.

This is from the qualification site FAQ.

Q. Do all products have to be go through the Bluetooth qualification
process?

A. Yes, any product that is to be sold with Bluetooth wireless technology
must be licensed. The Bluetooth Adopters Agreement is an intellectual
property license agreement that allows the Member to make and sell products
which 'comply with the Specification.' Qualification is the process by which
the Member demonstrates the product complies with the Bluetooth
Specification.

Note the phrase in the first sentence of the answer "any product ... with
Bluetooth Wireless Technology". No mention of the bluetooth logo.

OK, lets not make this a handbags at dawn discussion. :-) Also for others on
the PICLIST, Keith and I work for the same company but 6000 miles apart.

OK, by default the ericsson module complies to GAP, and hence as long as you
qualify your product and state that it conforms to GAP, then you do fulfil
any obligations that the Bluetooth Adopters Agreement binds you too.

You can then use a proprietry data format for everything else.

SW.

Nah, can't make it for dawn and anyway the wife's borrowed my handbag 8)

The point I was raising intially was that they would still have to be
*qualified* - even as only GAP compliant.

An uninformed reader of the earlier post may have thought they could just
buy the modules and use the technology without qualifying the product.

You and I *know* these things, so often forget to mention them to others as
they are obvious to us 8)

I notice that there is a new newsgroup

alt.cellular.bluetooth.

You may find useful information there.

That is useful, another one to try is http://www.egroups.com/groups/bluetooth there
are approx a few hundred messages per month, the majority of opinions/facts
stated are honest.

This is a another good site, and quite informative and helpful if you have
questions that are not already answered on the site.
