Abstract (en)
[origin: EP1363260A1] The method includes, in normal functioning mode, to synchronise at regular intervals, the compatibility modules of the different devices (1 and 2) and establishing a discontinuous radio communication link, during the consecutive separated temporal windows, between this central device (1) and the peripheral devices (2) corresponding to the cyclical limited activation periods of the central device and of these peripheral devices, repeated at regular intervals, with a frequency greater than the repetition frequency of the emission of the synchronisation message.
