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 documented in the nRF91 AT Commands Reference Guide and proprietary AT commands documented in SLM-specific AT commands.

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