Abstract

A slave device provides a service to a master device via wireless communication, e.g. via wireless docking. The master device has a graphical user interface arranged for generating a system image (400) for showing node elements (310, 311, 320) graphically representing the devices and services, e.g. on a touch screen. The user may draw a line (410, 420) on the touch screen between selected node elements causing a line drawing input being detected. The slave device now initiates a setup operation between selected devices corresponding to the selected node elements. The setup operation is subsequently performed by establishing a wireless connection between the selected devices. Advantageously, the user intuitively commands a wireless connection to be set up for using a service via wireless communication.
