Abstract
The invention relates to a bidirectional wireless transmission system for serial format data signals between a 'master' electronic device () and a 'slave' energy meter () including a microcontroller () having a serial input port (R). According to the invention, the serial format data signals are exchanged at short range via bidirectional electromagnetic coupling means () outputting a pulse on each rising or falling front in said serial format data signals. To transmit data signals from the “master” device () to the “slave” meter (), the pulses at the output of the electromagnetic coupling means () are delivered to said serial input port (R). The microcontroller () is programmed so that each pulse received on the input port (R) generates an interrupt, so as to synchronize the microcontroller on the first received pulse and so as to act at the serial data transmission speed to generate a succession of bits, the value of each generated bit being equal either to the value of the preceding bit if no interrupt has been received in the meanwhile, or else being equal to the inverse of the value of the preceding bit if an interrupt has been received in the meanwhile.
