Abstract
(EN)
A method of re-establishing a connection between a LWM2M client (110) and an LWM2M server (200) following a reconnection of the LWM2M client (110) to the LWM2M server includes determining (706), at the LWM2M client (110), a state of the LWM2M client (110) device prior to reconnection of the LWM2M client, transmitting (708), to the LWM2M server (200), an indication of the state of the LWM2M client (110) prior to reconnection of the LWM2M client (110), and receiving (710) a response from the LWM2M server indicating whether the indicated state of the LWM2M client (110) is an expected state or an unexpected state.
