ArduinoBt bluetooth pairing does not work

Hi list,

i am using a ArduinoBt board for quite some time and it worked great up to now. For some reason i can not pair the board with the default '12345' pass-key anymore. The board shows up in my bluetooth device list with it's name 'ARDUINOBT' but the pairing fails.

  1. Is it possible to reset the pass-key to the default one without a working bluetooth connection?
  2. If not, is it possible to wire the ArduinoBt board to a usb port to send it a new pass-key?

Thanks a lot,

stiwi

yes you can reset the passcode by uploading to the board. If you have lost your wireless connection, you may have to burn its bootloader again using a programmer like the AVR_ISP MKII or similar. Look in the wiki, there are reset insstructions there.

Hi Daniel,

I got it back to work with some info in the wiki. Now i am struggling with the Arduino IDE 0010. It does not work on OSX and Intel Mac. I think i have to wait for an update and use RAD in the meantime. Thanks for the reply.

stiwi.

hi

I have used 0010 on intel OSX, both 10.4.1 and 10.5, it works great.. Try downloading it again.

Nope. It always throws a device already in use exception. If i use avrdude directly via the terminal everything is fine. Strange. :frowning:

Hmm, it sounds like the problem is with RXTX, which is the serial library that the Arduino IDE uses to flush the serial port before launching avrdude. Do you have any versions of it installed in your Java folder (look for comm.jar or anything with rxtx in the name inside /System/Library/Frameworks/JavaVM.framework

Does the same thing happen with a normal USB Arduino board?

I am using a fresh Leopard install with the original java version 1.5.0_13. The only RXTX lib i could find on my system is the one in the Arduino 10.app/Contents/Resources/Java folder named RXTXcomm.jar.

Does the same thing happen with a normal USB Arduino board?

Sorry. I Only have the bluetooth version to play with :slight_smile: Maybe someboby else?

Right now i am using a modified version of the "Textmate/Arduino bundle" makefile i found on the net with the avr tools included in the arduino-0010 release.

cheers,

Hi,
I am also still having the problem of the Device already in use exception with the ArduinoBT using 10.5/10.5.1. It works fine with 10.4.10. And the Arduino Diecimila works fine through USB in 10.5.

A search for comm.jar and rxtx did not find any files outside the Processing and Arduino directories. I don't think I have installed any extra java-related software.
Your help is appreciated!
