3.6 AT Commands
The Skywire family of embedded modems communicates using AT commands. AT
commands are issued by typing the command, pressing the Enter key on your
keyboard, and observing the response.
3.7 Verify AT Command Communications
Type the following command:
AT
followed by the Enter Key, and the terminal should respond with:
OK
Please note: the default behavior of the NL-SW-LTE-SVZM20-ES is to not echo the
command back, so you will not see AT as you type it,
only the ‘OK’ response if Enter
key is pressed.
3.8 Enable Command Echo
To enable the command echo, type the following command:
ATE1
followed by the Enter Key, and the terminal should respond with:
OK
You will now see the commands as they are typed. This functionality will default back to
off with a power cycle. You can also disable the command echo by typing the following
command:
ATE0
followed by the Enter Key, and the terminal should respond with:
OK
3.9 Check Firmware Version
It is beneficial to make sure that you always have the latest firmware to ensure stability
and feature set. To check your firmware, type the following command:
ATI1
followed by the Enter Key, and the terminal should respond with:
UE6.0.0.0
LR6.0.0.0-xxxxx
OK
