- Thu Jun 15, 2017 12:40 am #67195 Just trying to run a small piece of code below. This is webap_toggle_pin.lua example from nodemcu repo.

Code: Select allwifi.setmode(wifi.SOFTAP)
wifi.ap.config({ssid="FAKE_ID",pwd="FAKE_PWD"})
gpio.mode(1, gpio.OUTPUT)
srv=net.createServer(net.TCP)
if srv then
srv:close()
end
srv:listen(80,function(conn)
    conn:on("receive", function(client,request)
        local buf = ""
        local _, _, method, path, vars = string.find(request, "([A-Z]+) (.+)?(.+) HTTP")
        if(method == nil)then
            _, _, method, path = string.find(request, "([A-Z]+) (.+) HTTP")
        end
        local _GET = {}
        if (vars ~= nil)then
            for k, v in string.gmatch(vars, "(%w+)=(%w+)&*") do
                _GET[k] = v
            end
        end
        buf = buf.."<h1> Hello, NodeMcu.</h1><form src=\"/\">Turn PIN1 <select name=\"pin\" onchange=\"form.submit()\">"
        local _on,_off = "",""
        if(_GET.pin == "ON")then
              _on = " selected=true"
              gpio.write(1, gpio.HIGH)
        elseif(_GET.pin == "OFF")then
              _off = " selected=\"true\""
              gpio.write(1, gpio.LOW)
        end
        buf = buf.."<option".._on..">ON</opton><option".._off..">OFF</option></select></form>"
        client:send(buf)
    end)
    conn:on("sent", function (c) c:close() end)
end)



When run, it gives the below error.

Code: Select all> dofile("init.lua");
init.lua:6: not connected
stack traceback:
   [C]: in function 'close'
   init.lua:6: in main chunk
   [C]: in function 'dofile'
   stdin:1: in main chunk



Any idea how to fix this?
