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
Note: From FW version R_00.07.03 this option is deprecated. IP addresses can be called with `ubus call network.interface.<interface> status`. For mobile interfaces use `ubus call network.interface.<interface>_4 status` for IPv4 or `ubus call network.interface.<interface>_6` for IPv6.
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.
Example: obtaining the IP address of the mobile connection interface:
root@Teltonika:~# gsmctl -p wwan0 10.139.75.221

SMS management options
This section overviews gsmctl options related to SMS management. Every SMS related command uses the "-S" or "--sms" along with another option.
Read SMS by index
To read a single SMS message, use -S -r or --sms --read options. Additionally you have to specify the <INDEX> of the message that you wish to read. The <INDEX> is an integer number that defines the position of a message in the SMS message list. It can range from 1 to however many messages your SMS memory can store.
Usage syntax:
gsmctl -S -r, --sms --read <INDEX>
Example: reading the first message in the SMS list

- out of range - indicates that the specified <INDEX> is out of range of the SMS message list
List SMS by type
To print a list of SMS messages, use -S -l or --sms --list options. Additionally you have to specify the <TYPE> of the list. <TYPE> can either read, new or all
Usage syntax:
gsmctl -S -l, --sms --list <TYPE>
Example: printing the list of all new (unread) SMS messages
root@Teltonika:~# gsmctl -S -l new Index: 19 Date: 2018-08-03 08:26:36 Sender: +37061111111 Text: status Status: new
