Before interrupting sleep, for example, with uplink data, the application must activate hardware components and ensure that resources are available for the modem. After this, uplink data or any other request can be sent to the modem. After modem activity, sleep is not resumed, but a new sleep period starts instead.
The following notification example indicates that the modem sleeps:
%XMODEMSLEEP: <type>,120000
The following notification example indicates that the modem sleep has ended:
%XMODEMSLEEP: <type>,0
