Adding bluetooth to msp430
Yo. Directly used and application notes on TI website how to integrate these modules and possible sample code in one of the 2 free IDE's

This is a BlueTooth 2.1 Module that can be interfaced in many ways to many other development kits. This is a cheap option for a complete module that does what it says- no messing about.

What did you say? How about Wifi?


Bluetooth 2.1 + WIFI b/g/n (but it needs an antenna- not expensive- good range!)


As a buy and use it solution after weeks of research those are good. but also there are many avaialble


look at this (but CSR dont like selling to end users.. after Apple bought a few million chips from them they seem to stuck their noses up theri a$$hsszz...


There are projects to build your own BT device - but i stronly suggest using a module as many hours of reseach went into these moduels to produce the best range and power consumption using good components.

It is a bit early - but this is a very impressive module from TI
C2450
Why early- becasue it uses BT version 4- which only Iphone 4S use (surprissee- it used this chip- suck o n that CSR!) and the specifications of BT4 are amazing- super low power, new methods of connecting using close range authentication, lower power advertising and pairing.. runs on a coil battery for years! But we have to wait till smart phones catch up.. I have not found any Smartphone that supports BT4 yet.(aprt form iPhone4s)

other problem is-- there is no module yet- so you would have to buy the chip, make a pcb, match and tune the aeriel and hope for the best.. 

Best of all - its ALL IN ONE- so you can programme this chip with 8 or 12 IO's i think so it can do all sort of clever things like your MSP430 (based on the new extreme low power MSP edition) So in the sample you would need 1 crystal- 2 balancing caps, 1 decoupling cap, and you might be able to use an on-board antenna to avoid tuning issues.
