Does not connect to brick.

[clplaneguy]

InteliJ IDEA/leJOS plugin does not connect to the Lego brick with Windows 7. The brick is connected by both USB and BlueTooth. But. no application connection is made. Program runs on the PC. Should the IP address be used or the brick name?

[miguelcordovam]

Use IP address, it usually takes a couple of minutes. I haven't tried on Windows 7. You need to create a run configuration for Lejos.

[clplaneguy]

1. Install plugin and restart IDE. Done Windows 7 IntelliJ IDEA: Version 2017.3.4 (Community Edition) LeJOS Plugin: Version 1.2

2. Create a lejOS project. Done Project name: 3-13-2018_leJOS_PROJECT

3. Go to File > Settings > Tools > LejOS Plugin. Done

4. Set EV3_HOME and brick's name (Default is 10.0.1.1). Done EV3_HOME: C:\Program Files\leJOS EV3 Name: 10.0.1.1 File > Settings > Tools > leJOS Plugin is set

5. Write code to your EV3. Done I have created a leJOS PROJECT/"Hello World" program.

6. Create a run configuration. Done I have a Run/Debug Configurations setting. Should it say something specific.

7. Enjoy your robot! Error The leJOS program(Hello World) does not find and is not looking for an EV3. I do not get an "EV3 not found" error. The program is running on the PC and is printing to the computer screen. That can be a nice option considering the small EV3 screen, but does not serve the purpose.

What am I missing?

Hi, are you using jdk7? Can you ping your ev3 from your pc? Can you open an ssh connection to it?

Ping successful: 0% loss ssh made successfully: It's been a long time. I do not remember what to do with it. jdk down graded from 9 to 7.

No change. Output sent to computer.

Please share your code, I will try to replicate your issue.

import lejos.hardware.Button;

public class hello_world { public static void main(String[] args) { System.out.println("3/13/2018 TTest runme"); System.out.println("Hellobbbbbbbbbbbbbbbb World!!");

    Button.waitForAnyPress();
}

}

Use: LCD.drawString("Test", 1, 1); to print text on the brick.

[clplaneguy]

Cannot resolve symbol 'LCD'

You have to import it: import lejos.hardware.lcd.LCD;

Editor comments:

Cannot resolve symbol Hello_World

Cannot resolve symbol AfterButton

Cannot resolve symbol waitForAnyPress

On execution: Program prints to the computer screen

3-13-2018 1

Hello_World

Then execution stops and does not print to the screen

AfterButton.waitForAnyPress

The EV3 is never accessed.

I was going to work with Scala. Does all this have nothing to do with Scala?

Scala is not supported, maybe that's the reason.
