Bluetooth.getPin() returns null instead of byte[]

[ciborro]

Hello,

I have some problems with pairing devices in lejos.
I can't add device for example, but on original firmware everything work's fine.

Some time ago I wrote really simple application to adding/deleting devices in lejos. It worked fine.

Now I'm trying to write better simple application for managing Bluetooth in lejos.
I recognize that function Bluetooth.getPin() don't work properly.

It returns null instead of byte[]. I enclose code example.

Code: Select all

public void ShowPIN()
    {
        byte[] pin = Bluetooth.getPin();
        if(pin == null)
        {
            LCD.clear();
            LCD.drawString("PIN unavliable!", 0, 1);
            LCD.drawString("Press any key...", 0, 2);
            Button.waitForAnyPress();
            return;
        }
        LCD.clear();
        LCD.drawString("Current PIN is:", 0, 0);

        LCD.drawInt(pin[0], 0, 2);
        LCD.drawInt(pin[1], 2, 2);
        LCD.drawInt(pin[2], 4, 2);
        LCD.drawInt(pin[3], 6, 2);
       
        Button.waitForAnyPress();
    }

Greetings.
Przemek.

The pin data is not loaded until the Bluetooth code is actually used. You may need to force this, try making a call to Bluetooth.checkDevice before you call getPin...

What problems are you having with pairing? Is there a reason why you can't use the leJOS menu to do the pair operation?
