A method for activating a wireless electronic detonator comprising an on-board primary source of energy, at least one functional module comprising at least one explosive fuse and an energy storage element dedicated to an ignition of said at least one explosive fuse, a power switch, disposed between the on-board primary source of energy and said at least one functional module, the power switch configured to connect or disconnect said at least one functional module and the on-board primary source of energy, and a controller to control the power switch, the method comprising steps of:
- receiving a light signal;
- demodulating the light signal received;
- generating a control signal, according to the demodulated light signal, the control signal being configured to at least control the power switch;
- and
- transferring energy from the on-board primary energy source to the energy storage element when the power switch is activated in response to the control signal.
