Hi there. I m new to using esp module. I would like to run it as an AP and connect it to my laptop (Which I managed to do). but I would like to send some bytes to it from my laptop. These bytes will be read serially by a microcontroller connected to esp.

With nodemcu firmware you just can set one server, but you can listen to one port and talk to another with a client.

Server:

Code: Select all

local SERVER = "192.168.1.25"
local PORT = "2222"
local socket = nil

function senddata()
    socket = net.createConnection(net.TCP,0)
    socket:on("connection",connected)
    socket:connect(PORT,SERVER)
end
function connected()
    local MY_IP_ADDRESS = wifi.sta.getip()
    socket:send("MY IP IS "..MY_IP_ADDRESS.."\r\n")
end

srv=net.createServer(net.TCP)
srv:listen(1111,function(conn)
    conn:on("receive", function(client,request)
     
        if(request == "Connect")then
          senddata()
        end
       
    end)
end)

Regards
