Receive UDP string

[leonidas]

It works, but if I make a script like this there is 5-10 delay of sending KNX address (in if statement) after UDP string is sent by the client:
I use this code as resident with 0s interval.
Any thoughts of making this script work faster?

Code:

if not server then
 require('socket')
 server = socket.udp()
 server:setsockname('*', 8891)
 server:settimeout(1)
end

data = server:receive()

local TerminalID = string.byte(data, 9, 12)
local FingerID = string.byte(data, 33, 36)

if (FingerID == 6 and TerminalID == 63) then
 grp.write('4/0/10', 1)
elseif (FingerID == 7 and TerminalID == 63) then
 grp.write('0/5/18', 0)  
end

Nevermind! I solved it by putting logic in "if data then" statement
