Abstract: The invention concerns a method and a system for rapidly establishing a communication, particularly a Bluetooth type communication, between at least one reader and a plurality of communicating objects. Each communicating object and said reader have a communication protocol. Each communicating object has a communication address. The method comprises: the step of defining a unique communication address for all of the communicating objects; the step, for said reader, of determining whether at least one communicating object is present in the environment in which said reader is located, by sending a request to the unique communication address of all the communicating objects; the step, for each communicating object that receives said request, of revealing its presence to said reader by sending a response signal that is time-shifted relative to the response signals sent by the other communicating objects.

Abstract: The invention concerns a method and a system for rapidly establishing a Bluetooth type communication between a reader and a communicating object. The Bluetooth type communication protocol implements a radio frequency communication process on channels having specific frequencies. The specific frequencies are divided into a first subgroup of frequencies and a second subgroup of frequencies. Each communicating object of alternately and successively selects a frequency from the first subgroup of frequencies followed by a frequency from the second subgroup of frequencies. The reader randomly selects the first subgroup of frequencies or the second subgroup of frequencies, and performs frequency scans of the selected subgroup of frequencies before performing a scan of the other subgroup of frequencies.
