MSP430 LaunchPad Wireless Communication via XBee Series 1 Modules

I am currently working on a project that will use ZigBee wireless technology to send data to hub. I'm not sure if anyone has used the XBee Series 1 (XB25) modules in conjunction with the MSP430 LaunchPad but strangely enough I tried connecting the UART pins from the LaunchPad to the DIN/DOUT pins on the XBee module (via a breakout from Sparkfun) and it had worked earlier (almost like magic). Now, for some reason, this exact same does not work anymore and I am curious as to why.

For reference, the current setup is a XBee Series 1 Module attached to a USB breakout board (also from Sparkfun) and we are trying to send info to it from a battery operated MSP430 LaunchPad connected to a XBee module. The MSP430 is set to send the character "M" when the PIR sensor detects motion. Currently, the XBee on the USB can send data to the other XBee (the RSSI LED on the breakout board on the wireless side is lit up), but when the MSP430 is sending data to the USB XBee, nothing shows up on it's COM port.

If there is a configuration problem with X-CTU, I may bring this up on Digi's website to see if they have any solutions as well. I am also open to other wireless solutions, but XBee seemed pretty simple compared to TI's RF BoosterPack for the LaunchPad.

Thanks in advance!

  • Are you able to verify (with a scope or logic analyzer) that the bytes are being sent over the wire?

    If you're looking to talk Zigbee with a LaunchPad, the guys over at Anaren have already done it for their module:


    Lots of good examples, too.
