HELP luasocket changed in build 31

[rocfusion]

Hi,

Please help.  I have the LM5 running RC1 firmware.  Luasocket is upgraded to luasocket_2.0.2-31_imx6.ipk  it was working in the 29 build.  This particular LM5 is running resident scripts for a websocket client which is working.  I really don't want to break that.

The UDP server does not receive when I have the TCP client active.  I can comment out the TCP client then it works.  The event script can send to the resident script fine.  I have tried changing the timeout value for both TCP client and the UDP server.  Makes no difference.  I need to use copas because I have delay commands sent out to the TCP device.   

Does anyone have an idea.

Resident script on 0 seconds

Code:

if not ready then
  copas = require("copas")
  socket = require("socket")

  server = socket.udp()
  server:setsockname("127.0.0.1",51034)
  function handler(uskt)
    uskt = copas.wrap(uskt)
    log("UDP connection handler")
    while true do
      local s, err
      log("receiving...")
      s, err = uskt:receive(1024)
      if not s then
        log("Receive error: ")
        log(err)
        return
      end
      log("Received data, bytes:")
      log(s)
    end
  end
  copas.addserver(server, handler, 0)
 
  function parse(data)
    log(data)
  end
 
  function sendtcp(command)
    skt:send(command)
    sleep(0.5)   
  end
   
  function init()
    log('in init')
    sendtcp('#COSMSGS=false\r')   
    sendtcp('#MODEL?\r')  
  end
  ready=true
end


if not skt then
  --add receive thread
  copas.addthread(function()
      local reconnect = function()
        skt, err = socket.connect('192.168.0.175', 4999)
        skt:settimeout(1)
        if(not err) then       
          init()
        else
          log('[tcp-client] error connecting ')
          return
        end     
      end
      if not skt or skt==nil or skt.state=='CLOSED' then
        reconnect()
      end
      if(skt)then
        while true do
          local resp,err = skt:receive('*r')
          -- if theres no connection start a new connection
          if(skt.state=='CLOSED')then
            if not resp then
              log("[tcp-client] Receive error: ")
              copas.removethread(skt)
              skt = nil
              break
            end
          else
            if(resp~=nil) then
              local fd,prtd = pcall(parse,resp)
              if(fd==false)then
                log("Error with parsemsg")
              end
            end
          end
        end     
      end
    end) 

end
copas.loop()

Event script

Code:

if event.type=='groupwrite' then
  local socket = require('socket')
  local client = socket.udp()
  local evt = event.dst..','..tostring(grp.getvalue(event.dst))
  log(evt)
  if client then
    client:sendto(evt, '127.0.0.1', 51034)
    client:close()
  end
elseif event.type =='groupread' then
  grp.response(event.dst,grp.getvalue(event.dst))
end
