I was doing tests with ultrasound and accelerometer with ArduinoBT,

ultrasound sensors. I made it work, but it is not stable, sometimes
PD receiving no data at all. Pduino works fine with 115200 with
analog sensors. I didnt do any test but it works.
Analog should be ok since dropped packages aren't a big deal, but
with digital it matters a lot, the difference between getting a
button press and not.
did you try ( or know anybody) interfacing ArduinoBT with PD using
accelerometer (2 axis) or with ultrasound (PING) sensors?
There are now some nice sensors that output analog values so they are
really easy to use with Arduino and Firmata:
3-axis accellerometer:

ultrasonic rangefinder:

Also, for the old pulseIn() PING sensors, it should be possible to
make a Firmata compatible firmware using the Firmata library. It's
alpha, but the Firmata firmware already uses the library to send
input data.

What kind of digital sensors? I do know that the Arduino does
have issues when running at 115200. I don't know if the ArduinoBT
also has these issues. It would actually be really helpful if you
could run an "echo test" on the ArduinoBT.
Here's the recent discussion of testing on the Arduino developers'
list:

hello Tim,
Pduino (http://at.or.at/hans/pd/Pduino-0.3.1.zip) works fine with
ArduinoBT for analog sensors, you need to change baud rate to
115200 both in firmware and also in [comport]'s initial value.
for ultrasound and accelerator sensors, pulse problem can be
solved by increasing the delay time in the arduino codes, however
this is not a stable solution. Sometimes it doesn't work at all.
Seems like digital sensors + ArduinoBT+PD needs another solution.
anyone has any experience with digital sensors + ArduinoBT+PD ?

I found that there were some people interested in getting Bluetooth
Arduinos
working with PD a few months ago. Anyone care to share the
results of
their experiments? We are currently looking at it and having no
luck
what so ever. There seem to be no online suggestions as to what our
nonsuccess might be related to...
cheers,
tim
