Claim 3:
4. A method of an electronic vehicle radio key a transportation vehicle, the electronic vehicle radio key having a BLE module and a control unit, the transportation vehicle designed both to transmit BLUETOOTH® Low Energy (BLE) advertising signals and to receive BLE advertising signals, the BLE advertising signals of the transportation vehicle being transmitted periodically with a first time interval, wherein the transportation vehicle is further configured to receive BLE advertising signals between the transmission of each two BLE advertising signals by the transportation vehicle, the method comprising:
transmitting at least one sequence of BLE advertising signals, repeated periodically at a second time interval such that the second time interval separates the transmission of the first BLE advertising signal in each sequence and retransmission of the first BLE advertising signal in the next sequence, wherein the at least one sequence contains at least two BLE advertising signals and the at least two BLE advertising signals are transmitted at times separated by a third time interval that is smaller than the first time interval, wherein the control of the timing of the repeated transmission of the at least one sequence of BLE advertising signals to the transportation vehicle is performed such that transmission is performed during a reception period for the transportation vehicle during which the transportation vehicle is able to receive BLE advertising signals transmitted as a result of itself not presently transmitting BLE advertising signals;
receiving at least one BLE connection request signal;
establishing a BLE data connection based on at least one BLE connection request signal and
transmitting and receiving BLE data signals via the BLE data connection.
