Thanks for the answer Mellis!
I uploaded the BT configuration reset sketch, the led happily blinked so it was executed for sure.
But still I get errors if I try to open the serial port without resetting the board. I'm on OSX 10.4.8.
I get this:
"Serial port already in use. Try quitting any programs that may be using it."
And this console message:
"processing.app.SerialException: Serial port '/dev/tty.ARDUINOBT-BluetoothSeri-1' already in use.
Try quiting any programs that may be using it. ..."
No other program is using the port (at least visible programs)
I have disabled the file exchange services from osx BT preferences,
and still I can only connect with the same procedure:
reset the board and press serialmonitor just after resetting.
With this I can always connect, but it's not really useful for a wireless device...
I have 2 boards, both behave in the same way, both are BT-V06.
Have checked the background processes of OSX that involve bluetooth, and maybe keep the port busy,
because it seems that I can connect only during the "reset pause"
and that once the code starts running there's no way to connect without resetting.
Found only this "blued" that should manage the BT connection but don't know exactly how to go further...
If anyone can help I'd really appreciate, I'm totally clueless and wanna use this boards...
Thanks for your attention,
