Bluetooth module?

Started by Robert Scott February 24, 2004
I'm looking for advice on embedded bluetooth.  I know there are
complete RS-232/Bluetooth modules for use on PCs, but space constaints
in my app requires a smaller form factor.  Ideally, I would like to
interface it to a PIC using the async pins directly (not RS-232).  Any
suggestions?

Look at www.blu2i.com (TDK) and look for the blu2i module. This is a 'smallish' board of 65 x 24 mm. Meindert

This module is tiny - not cheap though. http://www.rfsolutions.co.uk/products/radio_gsm_modems/Bluetooth_BRM01.htm -- Max

or look around for MSI Bluetooth addon card (MS 6968), it often comes bundled with MSI motherboard. The main board is also 65 x 24 mm (when you cut off useless trackless arrounding board). The main pain is with interconnect - it comes only with USB, CSR chip is BGA and RS232 lines are not on the board afaik (I tried to trace them with no luck, apparently those pins are not soldered and I dont feel like desoldering BGA). It may sound like not what anyone would like, but this baby is bundled with motherboards for FREE, or can be purchased for symbolic 2-5$.

address is fake.) I haven't used them, but we were looking at the SMT modules from www.blueradios.com. They are very small (12x18 mm with antenna). I didn't get the final pricing, but I believe that they may be a bit expensive. Also, I believe that they provide a lot of the protocol support so you can't get the full speed of the data link. Adam

Zeevo (http://www.zeevo.com) makes a "Blue Stamp" module (ZV3001) based on their TC2001 chip. We have been using them for a couple of years. At design time, they were the only company including prequalified SPP (serial port profile) with their chip. Zeevo is phasing out the TC2001 in favor of its ZV4002, which is the same chip but with external flash. They say off-chip flash is cheaper than trying to integrate everything. Supposedly the ZV4002 goes for ten bucks and you have to add flash, antenna, crystal and some passive components. -- Brad
