Hi Brothers,

I have bluetooth module transceiver rs232 bought from DealExtreme http://dx.com/p/wireless-bluetooth-rs232-ttl-transceiver-module-844080711?item=4, I am using it with arduino.

Search and pair the bluetooth to my PC then detect two COM Ports, (e.g: COM30 & COM31) So I try to connect with putty on COM30 then success and COM31 fail. but I am curious with Processing, why Processing could not by this code "Serial.list()" just detect the second COM31 only, not COM30. So I cannot using Processing to control arduino using bluetooth.

Have some issue on processing?

Thanks,
Luqman
