EVK-L2 setup for Internet browsing (Linux)
This section describes how to set up the EVK-L2 for browsing the internet with a Linux operating
system on a PC connected with the EVK-L2 over the USB interface of the TOBY-L2 series module.
Follow the board setup instructions described in section
(except the Windows OS settings) to
provide communication via the USB interface of the TOBY-L2 module. Use minicom or a similar
program to send AT commands to the TOBY-L2 module.
1.
Identify the CDC-ACM connected to the Linux OS (
ls /dev/ttyACM*
) and then launch minicom
to use this port. In the example below the port is
ttyACM0
.
2.
Use the AT terminal to enter the following AT command lines. Perform the following procedure
to activate an external PDP context with the preferred APN:
Command sent by DTE (user)

OK
Set the module in airplane mode. The module will
deregister from the network and both RF Tx and RF Rx
will be disabled.
AT+CGDCONT=1,"IP","ibox.tim
.it"
OK
