COMMUNICATION METHOD FOR A PRESSURE MONITORING SYSTEM

The invention relates to a communication method for a monitoring system comprising a wheel unit () intended to communicate with an electronic control unit () by way of Bluetooth® Low Energy communication in order to establish two-way communication between the wheel unit and the electronic control unit, the wheel unit being able to transmit periodic signals of short duration to attempt to connect to the electronic control unit, the electronic control unit being able to acknowledge the periodic signals by transmitting a frame of radiofrequency signals to the wheel unit. The method comprises a step of automatically adapting the radiofrequency transmission power of the wheel unit when the wheel unit is in “advertising” mode, during which the wheel unit transmits signals of variable radiofrequency power so as to determine a minimum radiofrequency power starting from which the electronic control unit is capable of acknowledging at least one signal by transmitting a frame of radiofrequency signals to the wheel unit.
