Sending an SMS Diagnostic Command
Follow the steps below to configure the router to optionally accept SMS diagnostic commands only from authenticated senders and
learn how to send SMS diagnostic commands to the router.
Navigate to the Services > SMS messaging > Diagnostics page
Confirm that the Enable remote diagnostics and command execution toggle key is set to the ON position. If it is set to OFF
click the toggle key to switch it to the ON position.
If you wish to have the router only accept commands from authenticated senders, ensure that Only accept authenticated
SMS messages is set to the ON position. In the White list for diagnostic or execution SMS messages section, click the
+Add button and enter the sender’s number in international format into the Destination number field that appears. If you
wish to also configure a password, enter the password in the Password field corresponding to the destination number.
If you would prefer to accept SMS diagnostic commands from any sender, set the Only accept authenticated SMS
messages toggle key to the OFF position.
Note: An alternative method of adding a number to the white list is to send an SMS message to the router, navigate to
Services > SMS messaging > Inbox and then click the button next to the message which corresponds to the sender’s
number.
Click the Save button.
Types of SMS diagnostic commands
There are three types of commands that can be sent; execute, get and set. The basic syntax is as follows:
execute COMMAND
get VARIABLE
set VARIABLE=VALUE
If authentication is enabled, each command must be preceded by the password:
PASSWORD execute COMMAND
PASSWORD get VARIABLE
PASSWORD set VARIABLE=VALUE
The following are some examples of SMS diagnostic commands:
password6657 execute reboot
get rssi
set apn1=testAPNvalue
SMS acknowledgment replies
The router automatically replies to get commands with a value and execute commands with either a success or error response. Set
commands will only be responded to if the Send Set command acknowledgement replies toggle key is set to ON. If the Send
command error replies toggle key is set to ON, the router will send a reply if the command is correct but a variable or value is
incorrect, for example, due to misspelling.
