copas connecting to tcp server cannot receive percentage

[rocfusion]

Hi,

Ok so I have a resident script using a copas udp server on the localhost to receive commands from knx objects (event script) , then there is a copas tcp client connecting to an tcp server on the local network. I did it this way so they don't block each other.  The issue I am experiencing is that when the tcp server sends out an percentage character the tcp client stops receiving anything else from the server.

Does someone have an idea?

Thanks,

Roger

Code:

if not ready then
 socket = require("socket")
 copas = require("copas")
 alert('not Ready')
 ready=true
 
 function parse(data)
   alert('parsing...  '..data)
 end
   
 function fromKNX(command)
  alert('from KNX.. '..command)
 end
 
 local server = socket.udp()
 server:setsockname("127.0.0.1",23456)
 function handler(skts)
   skts = copas.wrap(skts)
   alert("UDP connection handler")
   while true do
     local s, err
     alert("UDP receiving...")
     s, erro = skts:receive(2048)
     if not s then
       alert("UDP Receive error: ", erro)
       break
     end
     alert("Received data, bytes: "..s)
     fromKNX(s)
   end
 end
 copas.addserver(server, handler, 1)  
end

if not skt then
 alert('not socket')
 if skt then
   skt:close()
   skt = nil
 end
 -- create tcp client
 skt, err = socket.connect('10.10.10.41', 4999)
 skt:settimeout(0)
 copas.addthread(function()
     while true do
      local resp,err = copas.receive(skt)
       if not resp then
         alert("TCP Receive error: ", err)
         break
       end
       parse(resp)
     end
   end)
 -- connect ok, reset buffer
 if skt then
   alert('[tcp-client] connection ok')
   warningfailed = true
   init()
   -- error while connecting,
 else
   if warningfailed then alert('[tcp-client] connection failed (conn): %s', err) end
   warningfailed = false
 end  
end

copas.loop()
