I was following Tutorial: Local multiplayer with UDP/TCP (https://coronalabs.com/blog/2014/09/23/tutorial-local-multiplayer-with-udptcp/)
I created a simple messaging app with socket UDP methods a while back(last year or so)however when i tested the program again using the latest 2017.3184 build, I was not able to use the udp's sendto method.
local result,err = sendUDP:sendto( msg, "255.255.255.255", 11111 ) sendUDP:setoption( "broadcast", false ) --turn off broadcast print("sending result: "..tostring(result).." "..tostring(err))
Jul 09 02:55:06.740 sending result: nil refused Jul 09 02:55:06.851 sending result: nil refused
Did some digging on lua webpage(https://rawgit.com/diegonehab/luasocket/master/doc/udp.html) and it says:
"Note: In UDP, the send method never blocks and the only way it can fail is if the underlying transport layer refuses to send a message to the specified address (i.e. no interface accepts the address)."
Is corona sdk blocking out going messages to unconnected ip address?
