i just gave that a try, and it does the same thing.... im going to haved to play around with it a little more later...
the pijng sensor im using, only has one I/O pin, it actaully takes the "trigger pulse" in and then waits 200uS and then sends out the ultrasonic pulse, so that part of the code was copied right out of their demo code for the BS2. i have had it working before on a 877a, so i just copied my code from that.. im sure its just a stupid little thing...
it actually seems like maybe the baudrate is just a tiny bit off, but i can send the first command fine...
