Appendix 

A

 

Setting up AT terminal applications for 
communication with EVK-L2 

 
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;  for 
the setting values see section 1.8. 

Check  with  the  Windows  Device  Manager  to  find 
out which COM port is being used by EVK-L2. 

 

Figure 4: “Home” page 

 

4.

 

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

Connect

 button. 

 

5.

 

Retrieve  the  module  and  network  information  by 
clicking on the 

Get Info

 button. 

 

6.

 

The  module  information  is  retrieved  and  displayed 
on Home page. 

 

7.

 

Click  on  the 

AT  Terminal

  button,  found  at  the 

upper  right  of  the  Home  page.  A  new  window 
opens and the AT-command terminal is now ready 
for communication with EVK-L2.
