Trying to send a single character from a VD over HTTP

[Innervations 2]

I have created a simple VD with a single button. When I press the button the character "E" should be sent to the IP address and port below. I am using the following code as LUA for the button:

 

local http = Net.FHttp("192.168.1.100", 4660);
local response = http:GET("E");
fibaro:debug(response)

 

The http request goes out and is received by the target device but it is not receiving the "E" character. Sorry - cannot tell what it is receiving but there is no response coming back to the HC2 and the device is not switching ON.

 

The address:port and sending the character "E" works fine when I send over HyperTerminal. My guess is I am not constructing the GET statement correctly? 

Any advice is greatly appreciated.

I have been trying to use HTTP to send and receive messages from an OmniPro 2 controller without success. Based on @Turmoil posts and tutorial I am now having success using NET.FTcpSocket

 

Here is the LUA code on a button on the VD I am working on. Simply sends the character "A" to message the OmniPro 2 to arm the alarm. 

 

   local devId = fibaro:getSelfId();
   local ipAddr = fibaro:getValue( devId, "IPAddress");
   local tcpPort = fibaro:getValue( devId, "TCPPort");
   local timeOut = 5 * 1000;

   local vdConn = Net.FTcpSocket(ipAddr, tcpPort);
   local bytes, retc = vdConn:write("A");
   if retc > 0 then
        if retc == 2 then
             fibaro:debug( "Connection to ".. ipAddr ..":"
                  ..tcpPort .." not established");
          else
           fibaro:debug( "Write failed: "..retc);
          end;
       else
        fibaro:debug( "Write complete, sent: "..bytes.." bytes");
        vdConn:setReadTimeout(timeOut);
      local resp, retc = vdConn:read();
        if retc > 0 then
             if retc == 1 then
                  fibaro:debug( "Request timed out");
               else
                  fibaro:debug( "Read complete: "..retc.." - "..resp);
               end;
          else
         fibaro:debug( "Read complete, received: "..resp);
          end;
      end;
   vdConn:disconnect();
