In my code it dont work (if i remove the last to lines the server get 1 alarm but more is not possible)

Code: Select allsk=net.createConnection(net.TCP, 0)
    sk:on("receive", function(sck, c) print(c) end )
    sk:connect(8080,"192.168.43.1")
    sk:send("alarm!\r\n")
    sk:send("alarm!\r\n")
    sk:close()

Only close the connection after the last send has been sent or if the other end closes the connection -- use the sk:on() function and callbacks with the "sent" or "disconnection" selector.
