A wireless communication interface (2) of a communicating device (1) to which an identification address (BD_ADD) is assigned for communicating. The interface (2) includes radio frequency circuits (4) and a memory (32) for recording data relative to an operating test phase of the radio frequency circuits. According to the invention, the memory (32) is rendered hardware interdependent of the radio frequency circuits (4) of the communication interface (2). The identification address (BD_ADD) is written into the memory (32). Applications of the present invention include wireless networks and pico-networks such as "Bluetooth," "Zig Bee," and similar protocol.
