Hi there, found this topic whilst looking for something else, just thought I'd share what I found.
I flashed the nodemcu firmware to my ESP and used the following lua script to switch gpio0 which was attached to an led.
The esp acts as an access point that you can connect to, open the module's IP address and switch the led on and off.
You need to amend the code to gpio3 for gpio0 control

Code: Select all
wifi.setmode(wifi.SOFTAP);
wifi.ap.config({ssid="test",pwd="12345678"});
gpio.mode(1, gpio.OUTPUT)
srv=net.createServer(net.TCP)
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);
client:close();
collectgarbage();
end)
end)
