The LED will now be blinking on and off.

Note that since its in a loop, its not possible to get it to stop via the interpreter. To stop it, click theReset button again!

This code halts the processor during the tmr.delay, a smarter way to blink an LED is to use the timer capability to set off

the LED control (code from here)

Scanning & Connecting to WiFi

We'll continue with a quick demo of scanning for WiFi and connecting.

Once you're back at the Lua prompt, set the ESP8266 into WiFi Client mode with

Then you can run the scanner and have it print out the available AP's

or for more detail...

-- Pin definition

local pin = 3

local status = gpio.LOW

local duration = 1000

-- 1 second duration for timer

-- Initialising pin

gpio.mode(pin, gpio.OUTPUT)

gpio.write(pin, status)

-- Create an interval

tmr.alarm(0, duration, 1, function ()

if status == gpio.LOW then

status = gpio.HIGH

else

status = gpio.LOW

end

gpio.write(pin, status)

end)

wifi.setmode(wifi.STATION)

-- print ap list

function listap(t)

for k,v in pairs(t) do

print(k.." : "..v)

end

end

wifi.sta.getap(listap)
