A method for acknowledging an error message of an apparatus which, upon occurrence of an error, transitions from an operating mode to a safe mode, the method comprising:
- receiving an acknowledgment request of the apparatus via a radio interface of a first device;
- deriving data identifying the apparatus from the acknowledgement request by the first device;
- and
- sending a first acknowledgement message from the first device to the apparatus via the radio interface.
An apparatus comprising:
- a radio interface;
- and
- a circuit configured to control a system,
- wherein the apparatus is configured to transition, upon occurrence of an error, from an operating mode to a safe mode in which the safe operation of the system is not in danger despite the presence of the error,
- wherein the circuit is configured to send an acknowledgement request via the radio interface upon rectification of the error, and
- wherein the apparatus is configured to return from the safe mode to the operating mode in response to receiving a valid acknowledgment message.
A portable device comprising:
- a radio interface;
- and
- a circuit, the circuit being configured to receive an acknowledgement request from an apparatus via the radio interface, and configured to display the acknowledgement request to a user of the portable device, in response to a user request, encrypt an acknowledgement message with a key associated with the apparatus, and send the encrypted acknowledgement message to the apparatus via the radio interface.
