Ok, I'm back with a set of new problems:
I gave up on trying to connect arduino to Windows 7 via bluetooth. Now i'm running ubuntu 11.04 from USB. At the moment i have my arduino connected to bluetooth module. On linux the only thing i've done is pushed the bluetooth icon on system tray and pushed "set up new device". Then i've paired my PC with the Bluetooth module. Next, i've uploaded the following code to arduino:
void setup() {
Serial.begin(9600);
}
void loop() {
Serial.println(sensorValue, DEC);
}
Next, i tried running this command on linux terminal
sudo gtk-term
It starts running, but shows the error:
Control signals read: Input/output error
In port configuration i've only changed the bitrate to 9600, everything else is default (Parity = none, Bits= 8, Stopbits=1, flow control=none)
First question is: how to know which port my device is using?
Second question is: how to get it working?
