Anybody had a similar problem? I just purchased one of nkc's xbee shields, assembled it, and connected it to the unchipped arduino and attempted to change its parameters. I used Tom Igoe's processing sketch for serial communication between the xbee and the mac (takes care of the carriage return / "enter" key thing), but I can't seem to communicate with the xbee module. My understanding is that after every parameter correctly entered, it's supposed to confirm by responding "OK." I enter command mode by pressing "+++" and get an "OK" back, but it won't respond to any of the other commands I send it.
The power light blinks on and off regularly as well-- so do you guys think this is some kind of user error in the assembly or maybe something else on the software side ? Any help would be appreciated.
