The code sometimes uses "0" or "1" to indicate success or failure of AT commands. It's better to use meaningful error codes or return values to handle errors effectively.

You need to include necessary libraries, like #include , at the beginning of your code to use certain functions and features. Missing includes can lead to compilation errors.
