UDP commands

[Domoticatorino]

ok. I tried this:

function cmd (mioff)
-- edit ip address and port
ip = '192.168.1.32'
port = 5987

 local sock = require('socket').udp()
 if sock then
   sockendto(cmd, ip, port)
sockettimeout(200)
   data = sock:receive()
   sock:close()
 end
return data
end
log(data)

as event function I used this following:

require("user.milight")
mioff = string.char(0x31,0x00,0x00,0x00,0x03,0x04,0x00,0x00,0x00,0x01)
cmd (mioff)

But I received the error below:

User Library "Milight", Line 8: bad argument #1 to 'sendto' (string expected, got function).

Thanks.
