    Shame on Rich for not providing links with his YouTube videos.

    I couldn't find a page describing exactly what Rich did but if you use his search page and enter "xbee s2 W9GFO" you'll get a list of somewhat related links.

    I have some S2 related links listed in post #12 of my index.

    I think Rich had documented the project at Savage Circuits but a recent database crash caused the project to be lost.

    It shouldn't be too difficult. How to do it depends on which type of xbee's you're using.

    http://www.parallax.com/sites/default/files/downloads/122-32450-XBeeTutorial-v1.0.1.pdf

    This covers a lot of good stuff.

    The idea would be to build a data packet- the packet could include a start delimiter, packet ID and the string containing the text you wish to send.

    When the receiving xbee see's the start delimiter, it looks at the packet ID to validate it in some way, and then receives the string into a buffer on the propeller.

    Can't really give you much more help... but the link will give you lots of good information.

    Does your small board have a level shifter on the rx line? The S2 hacker port has a level shifter which output 5V logic. The XBee can be damaged by the 5V logic if a level shifter isn't used.

    You could use the XBee for one way communication if you don't have a level shifter to start with.

    I'd also start out with a very simple program. Like send a single character to tell the S2 to light a LED or play a song. Once you know the S2 is receiving signals correctly, you can work on getting it to write words.

    You might want to send W9GFO a private message with a link to this thread. He may have some suggestions and he might still have a copy of his completed projects somewhere.

    Yeah, I feel bad about that. Especially since nobody wants to re-post things they had before that got lost. And who can blame them?
