How to set up a Siretta Modem using SMS AT commands
■This application note shows how to send an AT command directly to a Siretta Modem using a Mobile phone or SMS relay service.
■The text messages (SMS) containing AT commands are sent from a mobile phone and are received by the Siretta modem and processed. The modem replies with the corresponding AT response via text message.
■This is a useful tool for initial diagnosis of the environment surrounding the Siretta Modem application.
■Note: This feature is available for the following ZETA modem models running on firmware version 25.21.220 or above:
▲ZETA-NLP-LTE1- Ultra Low Power LTE Cat 1 (EU) - Siretta - Enabling Industrial IoT
▲ZETA-NSP-LTE1 - Low Power LTE Cat 1 (EU) - Siretta - Enabling Industrial IoT
▲Potential future product: ZETA-NEP-LTE1.
■The SMS feature makes it easy for the user to communicate with a remote terminal (Modem)using a text message and acquire important information from the terminal about cellular networks that it is connected to, including the quality of the signal strength and information about the status of the modem including GPIO, network technology and serial configuration.
