How to disable the radio whenever possible

[zerg]

Hi,

I'm not sure what this code is doing and is it necessary ?

while [ $C -gt 0 ]; do
printf "\x02" > /dev/gpio/out
sleep 1
printf "\x00" > /dev/gpio/out
sleep 1

I wrote myself a short code , which can be used also if you have enabled cron. In the /usr/local/sbin/ez-setup file I wrote simple code just to switch on/off the wireless. If you remove thecomments it is only 4-5 rows.

#!/bin/sh
WLAN=`wl isup`
time=`/bin/date '+%b %e %H:%M:%S'`
if [ "$WLAN" = "0" ]; then
    echo "$time: Wireless was down, powering up!" >> /tmp/var/log/ez-setup.log && wl radio on
    echo "$time : You have 5 minutes to  connect to the router before wireless automatically shuts down" >> /tmp/var/log/ez-setup-pressed
    sleep 300
    echo "$time : End of 5 minutes" >> /tmp/var/log/ez-setup.log
    rm /tmp/var/log/ez-setup-pressed
 else
    echo "$time: Wireless was up, powering down!" >> /tmp/var/log/ez-setup.log && 
    wl radio off
fi

When I press the ez-setup, it starts/stops the wireless and creates "flag" file in order to mark that the button was pressed.

Then in the cron I start the following script to disable the wireless if it is not used. The purpose of the "flag" file is to assure that the wireless will be on for at least 5 minutes, so we can connect. Without it it may happen that we will switch on the wireless and in 10 seconds cron may stop it.
You may put this code in a script and start it every 5 minutes using cron.

#!/bin/sh

time=`/bin/date '+%b %e %H:%M:%S'`

WLAN=`wl isup`
if [ "$WLAN" = "0" ]; then
#echo "$time : Wireless is already down ! " >> /opt/var/log/ez-setup.log
exit
fi

if [ -f /tmp/var/log/ez-setup-pressed ]; then 
#echo "$time : Stop file still exists" >> /opt/var/log/ez-setup.log 
exit
fi

if [ $(wl assoclist | wc -l) -gt 0 ]; then 
#echo "$time : Wireless devices still connected" >> /opt/var/log/ez-setup.log 
exit
fi

echo "$time : Wireless automatically down " >> /tmp/var/log/ez-setup.log 
wl radio off
