# Message Structure
## Possible Improvements
As for now, we are not having a max abount of bytes the message may have,
so we are relying on the ability of the receiver to dynamically allocate a buffer for the message.

However, we could add a field to tell a PRIORI the length of the whole message.

Probably we would use between 8 B or 24 B to put this info

(This won't be a 2.0 version, as this is not a final document yet)
