Looking for bluetooth module

Started by Anton Erasmus August 28, 2004
Hi,

Can anyone recommend an inexpensive bluetooth module that one can
connect to a MCU via the serial, SPI or I2C port. I do not want to
write the prorcol stack myself. I should be able to use simple
commands to the module, and the module should handle all the
protocol specifics of bluetooth.

Regards
   Anton Erasmus

Haven't used any myself (yet), but here's some info:

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. Rob Young rwyoung@ieee.org
I am using BRM01 from RF Solutions.

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?

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.

I sure have seen one and held it in my hand.
DevKits are purchaseable at www.zen-sys.com .

We've used it with superb results.

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.

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.
