Use the net.tcp module to send and receive using tcp sockets
Source Code
-- send and receive tcp socket data
-- include port as part of hostname
local s = net.tcp.connect('hostname:8086')
s:send(Data)
local Ack = s:recv()
s:close()
-- specify port separately from host name
local s = net.tcp.connect{host=hostname, port=8086}
s:send(Data)
local Ack = s:recv()
s:close()
Description
Use the net.tcp module to send and receive using tcp sockets
Usage Details
Examples of using tcp sockets to send and receive data, using net.tcp.send{} and net.tcp.recv{}.
Note: This code does not work “out-of-the-box” you will need to change the hostname to point a valid tcp host first.
How to use the snippet:
- Paste the code into your script
- Change the hostname
