B4J Question GPIO: Simulate (hardware) button press

[JanPRO]

Hi,

in the attached picture you can see a hardware button.
I am trying to simulate the button press: When I use a wire and connect the red circled pins, I am able to do so. But I want to do it programmatically, so my question is, how I can bridge/connect these two pins with B4J+Raspberry?

Edit: I have found this http://astenor.free.fr/Arduino/Projet_15/Project_15-EN.pdf for the Arduino, I tried to get this working with a GpioPinDigitalOutput object, but the circuit is always closed, so the button is pressed all the time.

This means that you need to set the default state to high (true) and change it to low when you want to emulate a button click.
