Communication method for a pressure monitoring system

A communication method for a monitoring system comprising a wheel unit able to carry out measurements in a vehicle and an electronic control unit remote from the wheel unit, the wheel unit comprising a first radiofrequency transceiver device intended to communicate with a second radiofrequency transceiver device provided in the electronic control unit by way of Bluetooth® communication enabling the short-distance two-way exchange of data using low-energy ultra-high-frequency radio waves to transmit the measurements to the electronic control unit and establish two-way communication between the wheel unit and the electronic control unit, the wheel unit being able to operate in an “advertising” communication mode in which it transmits 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, 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.
