L2 AT Commands
The content of Acklio FullSDK can be described in its simplistic view as an adaptation layer with the SCHC mechanisms, and a set of interfaces: the Management API, the Datagram API, the Network API and the L2A interface.
Refer to the diagram of layers and interfaces for a better understanding.
Most of the commands related to the L2 layers are commands implemented by Nordic semiconductor and are thus already documented in their infocenter.

AT%XSYSTEMMODE | InfoCenter | Allows configuring which types of connectivity are enabled (LTE-M, NB-IoT, GNSS, LTE). |
AT+CEREG | InfoCenter | Configures the subscription to URCs (Unsolicited Result Codes) for network status. This command should be called with parameter 5 so that the SDK can process connectivity events correctly. |
