DATA TRANSMISSION BETWEEN POWER SOURCE AND WIRELESS APPARATUS

Method for transmitting payload data in an electric power supply connector between a power source and a wireless apparatus is disclosed. Method includes: obtaining, by the power source, payload data to be transmitted; encoding, by the power source, the payload data using a predefined voltage modulation method; altering, by the power source, a voltage level of the electric connector in order to trigger the wireless apparatus to sample the electric connector; modulating, by the power source, the voltage level of the electric connector in order to transmit the encoded payload data to the wireless apparatus; and after detecting, by the wireless apparatus, that the voltage level of the electric connector is altered, starting, by the wireless apparatus, to sample the voltage of the electric connector in order to receive the encoded payload data, and decode the encoded payload data.
