Method and device for improving configuration of communication devices in a video projection system comprising multiple wireless video projectors

A method for configuring a wireless communication path between a master node and at least one slave node in a projection system for projecting a video stream on a projection area, comprising a plurality of video projectors, each of the master node and at least one slave node comprising at least one wireless communication module and at least one video projector of the plurality of video projectors, the method comprising the following steps:

• receiving a radio signal from the master node, in the at least one slave node, via a wireless communication module of the at least one slave node, the radio signal comprising at least one item of information characterizing the wireless communication module of the master node;
• upon reception of the radio signal, creating, in the at least one slave node, a sub-image comprising at least a representation of the at least one item of information;
• and
• displaying the created sub-image.

• displaying the created sub-image on the projection area;
• obtaining, in the master node, an image of the projection area;
• analysing, in the master node, the obtained image to determine whether the obtained image comprises at least a representation of the at least one item of information;
• in response to the analysing step, retrieving, in the master node, the at least one item of information;
• and
• setting up the at least one wireless communication module of the master node as a function of the at least one item of information to configure a wireless communication path between the master node and the at least one slave node.
