NB3000-Line-Hd User Manual 4.2
Here is an example how one might adopt those functions:
/* check current city and enable the second WAN link */
location = nb_status ( " location " );
if
( location ) {
city = struct_get ( location , " LOCATION_CITY " );
if
( city == " Wonderland " ) {
for
( led = 0; led < 5; led ++) {
nb_led_set (led , LED_BLINK_FAST | LED_COLOR_RED );
}
}
e l s e
{
printf ( " You 'll never walk alone in %s ...\ n" , city );
nb_config_set ( " wanlink .1. mode =1" );
}
}
Running SDK
In the SDK, we are speaking of
scripts
and
triggers
which form
jobs
.
Any
arena
script can be uploaded to the router or imported by using dedicated user con-
figuration packages. You may also edit the script directly at the Web Manager or select one
of our examples. You will further have a testing section on the router which can be used to
check your syntax or doing test runs.
Once uploaded, you will have to specify a trigger, that is, telling the router when the script is
to be executed. This can be either time-based (e.g. each Monday) or triggered by one of the
pre-defined system events (e.g. wan-up) as described in Events chapter 5.7.7 . With both, a
script and a trigger, you can finally set up an SDK job now. The
test
event usually serves as a
good facility to check whether your job is doing well. The admin section also offers facilities
to troubleshoot any issues and control running jobs.
The SDK host (sdkhost) corresponds to the daemon managing the scripts and their opera-
tions and thus avoiding any harm to the system. In terms of resources, it will limit CPU and
memory for running scripts and also provide a pre-defined portion of the available space of
the storage device. You may, however, extend it by external USB storage or (depending on
your model) extended flash storage.
Files written to
/tmp
will be hold in memory and will be cleared upon a restart of the script.
As your scripts operate in the sandbox, you will have no access to tools on the system (such
as
ifconfig
).
