Operating method for a wirelessly communicating electronic device, and wirelessly communicating electronic device implementing said method

An operating method for reducing energy consumption when sending a radiofrequency message by a wirelessly-communicating electronic device, the electronic device including an electronic control circuit including a memory and a radiofrequency transmitter configured to transmit a radiofrequency message, and a rechargeable electrical power storage including at least one non-rechargeable electrical battery, the rechargeable electrical power storage being configured to supply electricity to the electronic device, the method comprising:

• acquiring, by the electronic control circuit of the electronic device, a radiofrequency frame representative of at least one data item to be transmitted according to a communication protocol by the radiofrequency transmitter in a radiofrequency message;
• determining, by the electronic control circuit, an amount of energy available in the rechargeable electrical power storage;
• determining, by the electronic control circuit, the length of the radiofrequency message to be transmitted, the radiofrequency message comprising at least the acquired radiofrequency frame;
• determining transmission parameters of the radiofrequency transmitter, the transmission parameters comprising a selected operating class of a power amplifier of the radiofrequency transmitter, energy efficiency of the power amplifier being directed affected by the selected operating class of the power amplifier, the determining the transmission parameters being carried out by the electronic control circuit according to values determined for the length of the message and the amount of power available in the power storage;
• and
• transmitting the radiofrequency message by the radiofrequency transmitter according to the communication protocol, using the determined transmission parameters.
