Method for activating a connected object

A method for activating a connected object intended to function in a long-range wireless network and affording low energy consumption, the method comprises, when it is used by the connected object:

• detecting a first signal transmitted by an external device;
• when the first signal has predefined characteristics, making the connected object pass from a standby mode to an active mode, only a module of the connected object intended to detect the first signal being activated in standby mode;
• receiving a second signal comprising a signature from the external device;
• checking that the signature is in accordance with a predefined signature,
• when the signature is in accordance with the predefined signature, obtaining configuration parameters, configuring the connected object in accordance with the configuration parameters obtained and transmitting a message requesting connection to said network;
• at least some of the configuration parameters are received in a message transmitted by a server of said network following the transmission of the message requesting connection to said network by the connected object;
• and,
• following the transmission of the message requesting connection to said network by the connected object and prior to the reception of the message comprising said parameters, the connected object receives a message enabling connection to the network from the server comprising information indicating that the server has configuration parameters to transmit to the connected object and transmits a message acknowledging receipt for said enabling message so as to cause a sending by the server of the message comprising said parameters.
