puredata & arduino bt error message

I try to connect pd&arduino with standart firmdata with pduino. but when I open serial port I take an error message which is error: [comport] ** ERROR ** could not open device /dev/tty.Bluetooth-Modem: failure(16): Resource bus this is mac error message...

when I try with windows7 I take a RXERROR serial line message and shut down pure data.

I dont know what is the problem any advice will be cool.

is there any clue to solve the problem for this message.

if you take any advice will be greate. I want to use my bluetooth arduino.

You may find your answer in a pd or standart firmdata forum. I’d say it is probably bad code.

thank you for your message zoomkat, Actually I can use the same code with arduino board (diecmila).
