I was doing tests with ultrasound and accelerometer with ArduinoBT, beacuse of the pulse code in firmware PDuino doesn't work with that firmware, but I tried with earlier PD patch that I was using for 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,
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 ?
Koray.

Subject: [PD] arduino pd os x bluetooth
Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed
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
