The Network module manages the cellular connectivity for applications running on nRF91 Series devices. It handles network connection states, system mode configuration, and network power saving features such as eDRX (Extended Discontinuous Reception) and PSM (Power Saving Mode). It utilizes the LTE Link Control library from the nRF Connect SDK to control the modem and monitor network events. Internally, the module implements a state machine that uses Zephyr's State Machine Framework.
By default, the module automatically searches for a suitable network on startup and maintains the connection for the lifetime of the application. The library can also be configured to be fully controlled by the application instead, giving closer control over the LTE link and current consumption. See the Configurations section for more information.
