Claim 0:
1. An electronic vehicle radio key for a 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 electronic vehicle radio key comprising:
a BLE module having at least one BLE transceiver configured to transmit BLE advertising signals to the transportation vehicle, to receive BLE connection request signals from the transportation vehicle, and for communication of BLE data signals via at least one antenna; and
a control unit configured to:
activate the BLE module to control repeated transmission of at least one sequence of BLE advertising signals to the transportation vehicle, the repeated transmission of at least one sequence of BLE advertising signals being performed 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; and
activate the BLE module, based on at least one received BLE connection request signal from the transportation vehicle, to establish a BLE data connection to the transportation vehicle and to transmit BLE data signals via the BLE data connection.
