I have a simple C# TCP server based on the following Microsoft example:
But I cannot get my Arduino to connect to it using any of the examples (i.e. ChatServer, etc). My Arduino can successfully get an DHCP IP address, can request a web page, etc. All that works perfectly, I just can’t seem to connect to my TCP server program. I have set a static IP address, can ping the Arduino, etc.
Any thoughts are appreciated!
