        Hi Renzo

        The library provides ResponseContainer receiveMessageUntil(char delimiter = '\0'); which allows sending a string with a “\0” delimiter at the end. With this, the Receiver, when reading the buffer, identifies when a message starts and ends.

        Does the same happen when sending a Struct? I was analyzing the library code (I’m a beginner), but I didn’t identify which strategy is used to identify the beginning and end of a Struct in the buffer.

        How does ResponseStructContainer receiveMessage(const uint8_t size); know/identify when a Struct ends and starts another Struct in the buffer?

        If there is no such identification, if the developer makes a mistake in the buffer reading strategy, will this cause a memory leak?

          Hi George,
          for a structure, with a fixed size, you do not need to identify the end of the struct, you already know the size.
          If you have some different messages, you can use a simple trick like this (read the first part of the struct to understand the type).

          Bye Renzo
