That’s ok but you run the risk of flooding the socket if the server will send a lot of messages rapidly as you are only reading one line every 100ms. I strongly suggest you read until you get nothing (data == nil and error = “timeout”)
Ok. Added a repeat loop to get all the data. Works well. I also start up the listener on “applicationStart” When I restart the simulator the app no longer connects to the server. I can’t figure out how to make sure the client reconnects every time. Here’s the code and the output:
The code:
tcp = socket.tcp() listener = {} --networking functions tcpmonitor = {} function tcpmonitor:timer (event) local listening = true local client = tcp:getpeername() if client == nil then local status, sterr = tcp:connect(Data.address, Data.port) end timer.pause(listener) repeat local data,error = tcp:receive() print("=== client", client) print("+++ status", status) print("\>\>\> sterr", sterr) print("\*\*\* data", data) print("--- Error:", error) if data ~= nil then cnet.handleMessage(data) listening = false else -- error handling goes here end until data == nil or error == "closed" timer.resume(listener) socket.sleep(0.01) end local handleRuntimeEvents = function (event) print("\*\*\*\*\*\*\*\* event.type", event.type) if event.type == "applicationStart" then print("\*\*\*\*\*\* application started............") tcp:settimeout(0) tcp:bind("\*",9999) listener = {} listener = timer.performWithDelay(100, tcpmonitor, 0) elseif event.type == "applicationExit" then tcp:close() -- timer.cancel(listener) -- listener = {} end end Runtime:addEventListener("system", handleRuntimeEvents)

server side does not show any connection.
You might have a problem with bind. I don’t know why you need it as you’re not opening a server socket you are connecting to your server. Try removing that. Also print the result of the connect.
And what do you have to do to get it working again afterwards?
It might be a problem on the server also.
You were soooooo right! Removing bind did the trick. I also discovered that I really need to kill and restart the socket for a new login. The tcp stuff is working really well right now.
I just cancel the listener and close the tcp socket and reinitiate both. Humming along now.
Thanks for all your help.
There are still the UDP connections to worry about, but I’ll put up another topic if I need help on those.
I really appreciate the help.
