1 month ago The baud rate of 320 Pi is 115200. The default baud rate in Server.py is 1000000, so you need to change the last line of Server.py.

Describe the bug I ran the TCP IP communication example, but server-client communication does not work. The port you are trying to communicate with is opened, but no values can be sent from the server to the client. When I try to send a value from the server, an error occurs saying the connection has been lost. Thanks for letting me know what I'm missing.
