Hi, I'm new with Xbees, so please bear with me and my basic question.
I am working on a small project with 2 XBEEs on two Parallax Basic Stamps. I've downloaded some sample code from Hebel's "Getting Started with XBees" (page 75 and 76). On Stamp 1, you push a button and on Stamp 2, a LED and buzzer sounds. With each push of the button the buzzer pitch changes higher (and as stated the LED lights).
With 2 standard Xbee S1's the code works great, as it's supposed to.
Here's where it gets weird:
When I swap out the standard S1s to Pros, the code works, but it's slightly off. The pitch change for the buzzer does NOT work. The buzzer does sound, but only sounds at one constant pitch.
If I change the Xbees BACK to standard S1s, the code works as intended. So my code didn't change, and the stamps are not faulty.
If I change out ONLY the sending Stamp to a Pro, then it acts up again.
But if I change out ONLY the receiving Stamp to a Pro (and the sending unit is a standard Xbee), it works fine.
Any thoughts why this might be happening?
