Template:Gsmctl commands

The information in this page is shown in accordance with firmware versions {{{fw_version}}}.

Introduction

gsmctl is an SSH command used to communicate with a {{{name}}} router's modem. In other words, gsmctl relays AT commands (a set of instructions used to control a modem) to the router's modem; thus, providing the user with a way to control and obtain information from the modem via SSH. This can be used to either obtain certain modem related variables (signal strength, operator, connection state, etc.) or to execute certain actions (sending SMS messages, changing the frequency band, etc.).

This article provides a complete overview on gsmctl commands available in {{{name}}} routers.

Prerequisites

gsmctl commands can be used on all {{{name}}} routers via any type of command line interface (CLI) supported by the router. So all you need is:

a {{{name}}} router
knowledge on how to login via a command line interface

gsmctl options

gsmctl commands are used in tandem with various options that specify what type of action should be executed.

Example structure

Individual options are described in separate subsections of this article. To find the information you are looking for faster, refer to the table of contents at the top of the page or use your browser's "Find in page" feature (Control + F).

Each option is presented with its usage syntax and an example command. For easier differentiation of the different elements that make up the examples, different colors are used:

options are highlighted in blue
responses are highlighted in red
additional parameters are highlighted in purple

Two execution methods

Each option can be executed in two distinct ways. One is shorter, the other is longer and more descriptive. For example, to obtain the modem's IMEI you can either use:

short version: gsmctl -i
long version: gsmctl --imei

In both cases, you just type the desired command and press the "Enter" key on your keyboard to execute that command. The response will be printed out as a standard output (stdout) string in your terminal window.

Combined options

Multiple options can be combined together to obtain more than one parameter at a time. For example, to obtain the name of the operator used, signal strength and connection type with one command you can use one of the following:

short version: gsmctl -oqt
long version: gsmctl --operator --signal --conntype

Note that in the shorter version multiple options can be used together with one hyphen (-) symbol with no spacing, while in the longer version different options must be separated by spaces and before each option a double hyphen (--) is required.

Basic options

This section overviews basic gsmctl options, usually related to obtaining certain modem related information.

Get IP address of logical interface

To obtain the IP address of a network interface, use -p or --ip options.

Usage syntax:

gsmctl -p, --ip <INTERFACE>

Where <INTERFACE> is the name of a network interface.
