Method for activating a connected object during insertion thereof in a Low Power Wide Area Network LPWAN wireless network, the method comprises when it is implemented by the connected object: detecting, in a standby mode, where only one module of the connected object intended for detecting a first signal is activated, said first signal transmitted by an external device; when the first signal has predefined characteristics, making the connected object pass from the standby mode to an active mode; receiving, in the active mode, a second signal comprising a signature from the external device; checking that the signature is in accordance with a predefined signature, and when the signature is in accordance with the predefined signature, obtaining (3054, 407) configuration parameters from a server of said network, configuring the connected object in accordance with the obtained configuration parameters and transmitting (309, 4071) a message requesting connection to said network; characterised in that the method comprises: at least some of the configuration parameters are received in a message transmitted by the server of said network following the transmission of the message requesting connection to said network by the connected object; and in that following the transmission of the message requesting connection to said network by the connected object and prior to the reception of a message comprising said parameters, the connected object receives from the server an authorization message authorizing connection to the network comprising information indicating that the server has configuration parameters to transmit to the connected object and transmits an acknowledgement message acknowledging said authorization message so as to cause the server to send the message comprising said parameters. detecting, in a standby mode, where only one module of the connected object intended for detecting a first signal is activated, said first signal transmitted by an external device; when the first signal has predefined characteristics, making the connected object pass from the standby mode to an active mode; receiving, in the active mode, a second signal comprising a signature from the external device; checking that the signature is in accordance with a predefined signature, and when the signature is in accordance with the predefined signature, obtaining (3054, 407) configuration parameters from a server of said network, configuring the connected object in accordance with the obtained configuration parameters and transmitting (309, 4071) a message requesting connection to said network; characterised in that the method comprises: at least some of the configuration parameters are received in a message transmitted by the server of said network following the transmission of the message requesting connection to said network by the connected object; and in that following the transmission of the message requesting connection to said network by the connected object and prior to the reception of a message comprising said parameters, the connected object receives from the server an authorization message authorizing connection to the network comprising information indicating that the server has configuration parameters to transmit to the connected object and transmits an acknowledgement message acknowledging said authorization message so as to cause the server to send the message comprising said parameters. at least some of the configuration parameters are received in a message transmitted by the server of said network following the transmission of the message requesting connection to said network by the connected object; and in that following the transmission of the message requesting connection to said network by the connected object and prior to the reception of a message comprising said parameters, the connected object receives from the server an authorization message authorizing connection to the network comprising information indicating that the server has configuration parameters to transmit to the connected object and transmits an acknowledgement message acknowledging said authorization message so as to cause the server to send the message comprising said parameters.
