When to use "tcpSocket:disconnect();" ?

[Guest samuelboerhoop]

When do I use the following code in lua:?

 

tcpSocket:disconnect();

 

i some sample code it has been added to the sample in others not.

 

example:

 

-- Volume 40dB --

tcpSocket:write("MV40".."\r")

fibaro:sleep(500);

result, err = tcpSocket:read();

tcpSocket:disconnect();

if (err == 0) then

  fibaro:log("transfer OK");

  fibaro:debug("transfer OK");

else

  fibaro:log("transfer failed");

  fibaro:debug("transfer failed");

end

 

------------------------------------

 

 

-- HERE its not been used --

 

tcpSocket:write(string.char(0x53, 0x49, 0x49, 0x52, 0x41, 0x44, 0x49, 0x4f, 0x0d));

fibaro:sleep(1000);

result, err = tcpSocket:read();

if (err == 0) then

  fibaro:log("Transfer OK: Internet Radio");

else

  fibaro:log("Transfer failed: extra check");

  -- check source: needs 2 times... otherwise still failed...

  tcpSocket:write(string.char(0x53, 0x49, 0x3f, 0x0d));

  fibaro:sleep(500);

  result, err = tcpSocket:read();

  tcpSocket:write(string.char(0x53, 0x49, 0x3f, 0x0d));

  fibaro:sleep(500);

  result, err = tcpSocket:read();

  if (err == 0) then

    if ( trim(string.sub(result, 1, string.len(result)-9)) == 'SIIRADIO' ) then

      fibaro:log("Transfer OK: Internet Radio");

    else

      fibaro:log("Transfer failed");

    end

  else

    fibaro:log("Transfer failed");

  end

end

Where can I find a reference manual/page about this TCPsocket? I've searched the web, but all I can find is examples of one type of application (to see if a device is present on the network or not). I would like to be able to see what all of its variables do. I noticed that the readTimeout does not work as expected; the socket takes ages (>20 seconds) if no device is available, i.e. write returns an error. I would like to shorten this time-out, but changing readTimeout doesn't do the trick.

Would be nice if the Fibaro adinistrator not only moves the subject, but also anwers the question about where to find documentaiton of TCPsocket

It is of course used to close the connection and dispose the socket. It is more of a good practice question. You should close things like that.

Ok If you look at the last example below where should i place the sentence: tcpSocket:disconnect(); ?

 

After every "result, err = tcpSocket:read();" OR at the end of the last sentence of the code "result, err = tcpSocket:read();" ?

Because in the example the "result, err = tcpSocket:read();" appears 3x times ?

 

----- Example ----

tcpSocket:write(string.char(0x53, 0x49, 0x49, 0x52, 0x41, 0x44, 0x49, 0x4f, 0x0d));

fibaro:sleep(1000);

result, err = tcpSocket:read();

if (err == 0) then

  fibaro:log("Transfer OK: Internet Radio");

else

  fibaro:log("Transfer failed: extra check");

  -- check source: needs 2 times... otherwise still failed...

  tcpSocket:write(string.char(0x53, 0x49, 0x3f, 0x0d));

  fibaro:sleep(500);

  result, err = tcpSocket:read();

  tcpSocket:write(string.char(0x53, 0x49, 0x3f, 0x0d));

  fibaro:sleep(500);

  result, err = tcpSocket:read();

  if (err == 0) then

    if ( trim(string.sub(result, 1, string.len(result)-9)) == 'SIIRADIO' ) then

      fibaro:log("Transfer OK: Internet Radio");

    else

      fibaro:log("Transfer failed");

    end

  else

    fibaro:log("Transfer failed");

  end

end

It should be closed after last possible occurrence of utilizing this socket.
