nRF91 AT Commands Command Reference Guide

2021-10-15
■Introduction
●This document describes the AT commands used to control the modem in nRF91 Series devices. The nRF91 Series AT command API enables modem control for firmware running in the application core on nRF91 Series devices.
●The AT command API can also be exposed on one of the nRF91 serial interfaces by programming appropriate firmware in the application core. The nRF Connect SDK contains examples of such proxy firmware that can be run stand-alone or as part of other firmware functionality in the nRF91 application core. The stand-alone example is called at_client. This way, an external MCU or computer can get access to the modem API either exclusively or in addition to application firmware running on the nRF91 itself.
●The AT commands described in this document apply to all versions of the nRF9160 module hardware. If a command applies only to a specific version of the module hardware, it is mentioned in the command description. The module hardware version is printed on the module label. For more information on nRF9160 module hardware versions, see nRF9160 Compatibility Matrix.
