Controlling electronic devices by aerial vehicles

Abstract

An electronic device comprises a sensor arrangement, a control system operable to obtain sensor data from the sensor arrangement, and a microphone configured to provide an audio signal representing sound waves received by the microphone. The control system processes () the audio signal for detection of an audio characteristic feature, ACF, representing an operating parameter of a propulsion system in an aerial vehicle, and, upon said detection, performs () a dedicated action related to the sensor data. The dedicated action may comprise obtaining and/or transmitting at least part of the sensor data. To control the electronic device, the aerial vehicle is configured to, intermittently while on a flight path, cause its propulsion system () to impart a predefined and audible modification of an operating parameter of the propulsion system () to thereby generate sound waves that include the ACF.
