Setting up AT command interface

To control the nRF9160 LTE modem with AT commands, an application program that routes AT commands from the computer is needed. Nordic offers the AT Host application for this purpose. The AT Host firmware needs to be compiled according to the product hardware pin mapping.

nRF Connect SDK includes AT Host's source code. The compiled AT Host firmware is available for the nRF9160 Development Kit (DK) at nRF9160 DK Downloads. For more information on AT Host, see nRF9160: AT Host.

Available AT commands can be found in nRF91 AT Commands Reference Guide.
