Serial LTE modem

The Serial LTE Modem (SLM) application can be used to emulate a stand-alone LTE modem on an nRF91 Series device. The application accepts both the modem-specific AT commands and proprietary AT commands. The AT commands are documented in the following guides:

• Modem-specific AT commands - nRF91x1 AT Commands Reference Guide and nRF9160 AT Commands Reference Guide

• Proprietary AT commands - SLM-specific AT commands

See the subpages for how to use the application, how to extend it, and information on the supported AT commands.
