The method includes a step of generating a magnetic signal with an electromagnetic functional unit, wherein the electromagnetic functional unit is an actuator of a loudspeaker of the device or wherein the electromagnetic functional unit is an electromagnetic resonant circuit connected to the device, wherein the magnetic signal carries the data to be transferred from the device to the other device: Furthermore, the method includes a step of detecting the magnetic signal with an electromagnetic resonant circuit of the other device in order to obtain the data to be transferred from the device to the other device, wherein the magnetic signal is FSK-modulated, wherein a resonance frequency of the electromagnetic resonant circuit of the other device and a carrier frequency of the FSK-modulated magnetic signal are tuned with respect to each other.

Efficient communication to configure sensor nodes

A data receiver is configured to receive a signal including a plurality of partial data packets, wherein the plurality of partial data packets each include part of a data packet, wherein the data receiver includes a multi-stage correlator that is configured to perform multi-stage correlation to detect the partial data packets in the received signal, wherein a second correlation stage of the multi-stage correlator operates based on correlation results of a first correlation stage of the multi-stage correlator.
