Hidden Green LED

[Foxtrot]

Hi,

So while digging around the NANO I discovered two LED devices labelled "ath9k-phy0" and "ath9k_htc-phy1". The first one isn't too interesting, but the latter, "ath9k_htc-phy1" is the device entry for a green LED on the NANO. Go ahead and look through the cutout for the female USB port, you should see it lit up.

I think these LEDs were left in by accident by the manufacturer for the second radio. And while it is pretty useless because you can't see the LED easily, you can control it.

If you'd like to mess with it, I recommend reading this and experimenting with different triggers.

To enable a simple blinking of the LED, edit "/etc/config/system" and place the following underneath the existing led config block.

config led
	option name	'wlan1'
	option sysfs	'ath9k_htc-phy1'
	option trigger	'timer'
	option delayon	'5000'
	option delayoff '2000'

Your config should then look a little like this:

config system
	option hostname Pineapple
	option timezone UTC

config led
	option name	'wlan0'
	option sysfs	'pineapple:blue:system'
	option trigger	'netdev'
	option dev	'wlan0'
	option mode	'link tx rx'

config led
	option name	'wlan1'
	option sysfs	'ath9k_htc-phy1'
	option trigger	'timer'
	option delayon	'5000'
	option delayoff '2000'

config 'timeserver' 'ntp'
        list 'server'     '0.openwrt.pool.ntp.org'
        list 'server'     '1.openwrt.pool.ntp.org'
        list 'server'     '2.openwrt.pool.ntp.org'
        list 'server'     '3.openwrt.pool.ntp.org'
        option enable_server 0

Back on 1.0.1, if you had an external wifi adapter plugged in before it boots, it would light up the green LED instead of solid blue. Not really sure why that happens, but it was pretty neat.

Actually I'm fairly certain the green you are seeing is the green from the newly discovered LED, leaking into the plastic lens.

The blue LED is a single color -- blue.

Yeah, that's what I said. The green LED lit up if you had an external adapter plugged in before boot, instead of the solid blue.

You can always get a custom case made for it and expose the led kinda like the custom raspberry pi cases they have

There's a spot for 3 more leds.

Aww man next thing you know you guys will be figuring out the hidden #### in the turtle!

But yeah we're aware of the debug LED. It'll most likely be gone in the next batch (most likely just unpopulated).

Surprised nobody caught the Easter Egg in the virgin out of the box firmware ;)

Thanks for reminding me about that, if you have a link to the .bin, i'll grab the picture :)
