Hi Phongvucba.

Here is a script example for controlling Chromecast:

Code:

-- ****** Control Chromecast with 1 byte object version 1.0 created by Erwin van der Zwart ******* -- -- **************************************** SET PARAMETERS *************************************** -- -- Chromecast IP address ip_chromecast = '192.168.10.23' -- Additional info from browser about -- http://192.168.10.23:8008/ssdp/device-desc.xml -- http://192.168.10.23:8008/setup/scan_results -- http://192.168.10.23:8008/setup/eureka_info?options=detail -- http://192.168.10.23:8008/setup/supported_timezones -- http://geeknizer.com/how-chromecast-works-chromecast-protocol-explained/ value = event.getvalue() require 'socket.http' function control_chromecast(uri, request)  local request_body = request  local response_body = { }  local res, code, response_headers = socket.http.request  {    url = "http://" .. ip_chromecast .. ":8008/" .. uri;    method = "POST";    headers =    {      ["Content-Type"] = "application/x-www-form-urlencoded";      ["Content-Length"] = #request_body;    };    source = ltn12.source.string(request_body);    sink = ltn12.sink.table(response_body);  }  return res, code, response_headers end -- Action on value 1 if value == 1 then     -- Start Youtube video     res, code, response_headers = control_chromecast('apps/YouTube', [[v=_iuBO1lkch8]]) end -- Action on value 2 if value == 2 then     -- Stop Youtube video     res, code, response_headers = control_chromecast('apps/YouTube', [[DELETE]]) end -- Action on value 3 if value == 3 then     -- Start Chromecast Homescreen     res, code, response_headers = control_chromecast('apps/ChromeCast', [[]]) end -- Log results resulthandling = false if resulthandling == true then  -- Handler for results  log("Status:", res and "OK" or "FAILED")  log("HTTP code:", code)  log("Response headers:")  if type(response_headers) == "table" then    for k, v in pairs(response_headers) do      log(k, ":", v)    end  else    -- Would be nil, if there is an error    log("Not a table:", type(response_headers))  end  log("Response body:")  if type(response_body) == "table" then    log(table.concat(response_body))  else  end end

Thank you very much !
I have the following code, via UDP:
sock = socket.udp ()
    sock: setTimeout (1)
status = sock: connect ('192.168.10.10', 5353)
== 1 if status bars --- TV on
--tivi else off
Similar to TCP, the code is correct?
thank so much
