Bluetooth in Embedded System

Started by pipi March 4, 2004
I want to develop a embedded system which has bluetooth capability (that is,
overall system = a microcontroller + bluetooth component), so it can talk to
a bluetooth-enabled PDA. So which chip should I choose for the bluetooth
component and also what microcontroller is good for the embedded system?

Thanks in advance.

Check the National website...they have some nice single chip solutions for interface directly to a serial or usb port. If you go to the Ericsson website, they actually direct you all over the place for Bluetooth stuff.

I use the TRBLU20 module from TDK. It has all bt stuff on one board and uses the serial profile, giving you a serial port to talk to and configure it with modem style AT commands. This module and the BT features in a PDA behave like a serial cable connection. Other options are, like Dave pointed out, the National LXM thingy. But beware: anything you put together yourself (chips, antenna's and stuff and put it on a board) needs te be approved. The benefit of using a complete solution like TDK's is that all approvals have been done for you (FCC). Meindert
