The code for expled used in the help desk article is here https://github.com/OnionIoT/fast-gpio/blob/master/scripts/expled.sh in case someone is looking.

I think using commandline browser like elinks or lynx might be possible to authenticate manually, though I can't seems to find the package on Omega or in the openwrt list.

At last, got it working after reading http://superuser.com/questions/756438/openwrt-wpa2-enterprise-radius-config-is-not-applied and https://wiki.openwrt.org/doc/howto/wireless.utilities#hostapd-mini_and_wpad-mini

Basically we need to replace wpad-mini with wpad which have support for 802.1x and EAP. In order to do that, we must first have access to internet via another non EAP wifi AP. Then do this

opkg update
opkg remove wpad-mini
opkg install wpad

Tested with the above configuration and it works, though sacrificing another 0.3MB of space. I'll give it a try to add this into wifisetup.sh

I tried configured it manually by calling uci set wireless.@wifi-iface[1].ssid etc... following what's inside wifisetup.sh and referring to https://wiki.openwrt.org/doc/uci/wireless#wpa_enterprise_client it just won't even attempt to connect. After executing wifi, I'm only getting.

IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
IPv6: ADDRCONF(NETDEV_UP): wlan0-1: link is not ready

It only works if I'm connecting to psk/psk2 SSID.

IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
IPv6: ADDRCONF(NETDEV_UP): wlan0-1: link is not ready
wlan0-1: authenticate with xx:xx:xx:xx:xx:xx
wlan0-1: send auth to xx:xx:xx:xx:xx:xx (try 1/3)
wlan0-1: authenticated

If I set the encryption to psk2 for an WPA2-EAP SSID, it won't even try to connect, or at least that's what I get from the console.

Below is the output from my cat /etc/config/wireless

Lol, I was searching for RGB LED, no wonder I didn't find anything here and at the help desk. That's what I've been thinking, you guys wouldn't have missed such a simple thing.

I'm on Arch as well, it works out of box. I'm guessing it's because I've got Arduino installed.

Regarding the error you posted, might be good to post it in Arch's forum as well.

I was looking around for information on the GPIO connected to the RGB LED on the expansion dock, didn't find any, so I tried to traced back using a multimeter. Below is the connection, please correct me if I'm wrong, otherwise at least this should help the next guy looking for it.

1kOhm current limiting resistors are connected to each pin

LED R  - GPIO17
LED G  - GPIO16
LED B  - GPIO15

Set GPIO to 0 to turn on and 1 to turn off. I'm guessing the invert is because most GPIO have better sinking capability than sourcing. I would have expect a slightly different resistor value, especially for Red as each color have different luminosity and to achieve a better "white" when all are turned on.

Below is some code to get started

#Setup export and GPIO direction
echo 17 > /sys/class/gpio/gpiochip0/subsystem/export
echo 16 > /sys/class/gpio/gpiochip0/subsystem/export
echo 15 > /sys/class/gpio/gpiochip0/subsystem/export
echo out > /sys/class/gpio/gpio17/direction
echo out > /sys/class/gpio/gpio16/direction
echo out > /sys/class/gpio/gpio15/direction

#turn off RGB LED
echo 1 > /sys/class/gpio/gpio17/value
echo 1 > /sys/class/gpio/gpio16/value
echo 1 > /sys/class/gpio/gpio15/value

#turn on R
echo 0 > /sys/class/gpio/gpio17/value
#turn on G
echo 0 > /sys/class/gpio/gpio16/value
#turn on B
echo 0 > /sys/class/gpio/gpio15/value
