Hiding a device
First Claim
1. A method where a first communications device and a second communications device, previously unknown to each other, communicate with each other wirelessly using short-range RF (Radio Frequency) technology, the second communications device being, at a certain moment of time, in a first mode where the address of said second communications device is determinable by means of an inquiry wirelessly sent to it, and in which method:
- the first communications device sends a first message to determine the address of the second communications device;
said second communications device receives the first message;
said second communications device generates and sends to the first communications device a second message in response to the first message, said second message containing the address of said second communications device;
a connection establishment process is carried out for establishing a connection between the first communications device and said second communications device, and wherein;
during the connection establishment process, or in response to successful completion of said connection establishment process, at least one of said first and second communications devices switches from said first mode into a second mode, in which second mode the communications device that has switched into said second mode does not respond to messages arriving at it that have been sent in order to discover the address of the communications device that has switched into said second mode.

Abstract
The object of the invention is a method where a first communications device (10) and a second communications device (20), previously unknown to each other, communicate with each other wirelessly using short-range RF technology, said second communications device being at a certain moment of time in a first mode where the address of said second communications device is determinable by means of an inquiry wirelessly sent to it. In the method, the first communications device (10) sends (31) a first message in order to determine the address of said second communications device, said second communications device (20) receives (32) the first message, and said second communications device (20) generates and sends (33) to the first communications device a second message in response to the first message, the second message containing the address of said second communications device. In the method, a connection establishment process (35-38) is executed to establish a connection between the first communications device and said second communications device. During the connection establishment process, or in response to successful completion of the connection establishment process, at least one of said first and second communications devices (10, 20) switches (40) from said first mode into a second mode, in which second mode, the communications device that has switched into said second mode does not respond to messages arriving at it which have been sent to discover the address of the communications device that has switched into said second mode.

14. A first communications device comprising a transceiver for wireless communication with a second communications device using short-range RF technology, the first communications device comprising two different modes, in the first mode of which the address of the first communications device is determinable by means of a query wirelessly sent to it and in the second mode of which the address of the first communications device is not determinable by means of a query wirelessly sent to it, the first communications device comprising:
-
said transceiver for receiving a first message sent by said second communications device, said first message having been sent in order to determine the address of the first communications device;
a processing unit and said transceiver for generating and sending a second message to said second communications device in response to the first message, said second message containing the address of said first communications device;
said processing unit and said transceiver for carrying out a connection establishment process with said second communications device to establish a connection between said first communications device and said second communications device, wherein said first communications device is configured;
to switch, during the connection establishment process or in response to successful completion of the connection establishment process, from said first mode to a second mode in which second mode it does not respond to messages arriving at it which have been sent to discover its address.
