Hello, I am trying to read a. Txt file on the memory card and pass this value to read IPAdrees and variable port, so I can change the values ??of IP and Port without the need to use the Arduino IDE and facilitating its use at least for my application if someone can give me a hint.
i did a quick search and found this Can SD Card be used to store ip address/MAC configs? - Networking, Protocols, and Devices - Arduino Forum
