The wifi.sta module connects if a loop is running?

Question

Im trying to detect when the module actually connects to my wifi AP, since .connect does not have a callback im doing something simple like this:

wifi.sta.config

If you use a recent dev firmware you can do something really event based :

wifi.setmode(wifi.STATION)
wifi.sta.config(SSID, PASSWORD)

function Success()
    tmr.stop(0)
    if (SERIAL_PRINT) then
        print("IP: " .. wifi.sta.getip())
    end
    wifi.sta.eventMonStop()
    wifi.sta.eventMonReg(wifi.STA_GOTIP, "unreg")
    dofile("mainProgram.lua")
end

function Failure()
    if (SERIAL_PRINT) then
        print("Unable to connect")
    end
    wifi.sta.eventMonStop()
    wifi.sta.eventMonReg(wifi.STA_GOTIP, "unreg")
    return 0
end

tmr.alarm(0,30000,0, function() Failure() end)
wifi.sta.connect()
wifi.sta.eventMonReg(wifi.STA_GOTIP, function() Success() end)
wifi.sta.eventMonStart()

EDIT: Please have a look to the documentation for a list of all events. If you wish to use this code, you'll have to handle the failure more cleanly.
