Support for button scripts in MT300A and AR300M

Technical Support for Routers
1

Could you please advise me what are my options for button scripts (both reset button and the slider) with both GL and vanilla editions of OpenWrt for MT300A and AR300M?

I need to write a script which will run when either reset and/or slider is toggled.

2

the reset script should always be /etc/rc.button/reset

The switch script should use different names according to the module. In our firmware, you will find these script already, which just echo some text to console.

MT300A : /etc/rc.button/BTN_1

AR300M: /etc/rc.button/BTN_1

AR150: /etc/rc.button/BTN_8

I’m trying to use this with the image built with your image builder on MT300N and /etc/rc.button/BTN_1 doesn’t seem to be triggered on slider switch.

Also, how can I poll the switch status on boot?

4

Figured out the button ID with the simple /etc/hotplug.d/ script – it’s BTN_0.

Still, how can I poll the button status when the router is starting?

Follow up question – how do I control on/off and the color of the /sys/devices/gpio-leds/leds/gl-mt300n:wan LED?

You cannot control the color. It is only one color LED.

To turn on/off, use the following

echo 1 > /sys/class/leds/gl-mt300n:wan/brightness

echo 0 > /sys/class/leds/gl-mt300n:wan/brightness

To check the button status when router start, check /etc/init.d/initswitch script in our firmware

Thank you for your prompt reply. I’ve tried echo 0/1, but I was looking at a wrong LED and thought they didn’t work – they of course do.

I’ve checked the file you referred to, but I can’t see anything relevant to MT300N there (with MT300N and firmware 2.22):

#!/bin/sh /etc/rc.common

 

START=19

 

start(){

 

model=$(awk ‘BEGIN{FS=“-”} /machine/ {print tolower($2)}’ /proc/cpuinfo)

switch_left=

switch_disabled=“0”

 

case “$model” in

“ar150”)

switch_left=$(grep -o “BTN_8.*hi” /sys/kernel/debug/gpio)

“ar300m”)

;;

“mt300a”)

;;

“mt300n”)

;;

 

“connect inet v1” | \

“ar300” | \

“mt750” )

switch_disabled=“1”

;;

esac

 

#if switch is on 0

if [ “$switch_disabled” = “1” ]; then

exit 0

fi

}

So how can I poll the slider position on MT300N?

ah, nevermind: $(grep -o “BTN_8.*hi” /sys/kernel/debug/gpio)

Hi - on my MT300A, when i slide the swtich, nothing is echoed to console.

i’m on the 2.23-7 firmware.

Can someone write a script to set the boot count to 3 and 0 respectively with the other switch position and a reboot after setting the boot count… I’m not much for scripting.
