A

 

Setting  up  AT  terminal  applications  for 
communication with EVK-N2 

The u-blox m-center cellular module evaluation tool is a powerful platform for evaluating, configuring 
and testing u-blox cellular products. m-center includes an AT commands terminal for communication 
with the device and can be downloaded free-of-charge from our website (http://www.u-blox.com). 
 

1.

 

Follow the board setup instructions in section 

1.8

 to provide all the required connections and 

switching on the cellular module. 

 
2.

 

Run the m-center tool: after the m-center start-up, the Home page appears. 

 
3.

 

On the Home page, set up the AT COM port 
with the setting values described in section 

1.8

. 

Check with the Windows Device Manager to 
find out which COM port is being used by  
EVK-N2. 

 

 

Figure 3: “Home” page 

4.

 

Enable the connection to u-blox cellular 
module by clicking on the Connect button. 

 
5.

 

Click on the AT Terminal button (upper right 
of the Home page). A new window opens and 
the AT command terminal is now ready for 
communication with EVK-N2. 

 
6.

 

The AT terminal is ready to use. Click on the 
drop-down menu on the upper right of the AT 
command terminal and select SARA-N2 to 
get the list of supported AT commands.  
For the complete list of AT commands 
supported by the modules and their syntax, 
see the SARA-N2 series AT Commands 
Manual 

[1]

. 

 
7.

 

In case it is required to collect a trace file, open 
a second m-center window and set the AT 
COM port according to the instructions 
provided in sectio

1.8

. 

 

The  trace  interface  is  available  over  the 
second numbered COM port opened when a 
USB  cable  is  connected  to  the  mini  USB 
connector (J501)

For more information using the u-blox m-center cellular module evaluation tool, press the F1 key on 
the keyboard to open the m-center help window on the computer.
