PRO-TIP: The library supports building a message in any order. However, given the structure of the CoAP message, some memmove calls will be necessary.

It is slightly more efficient to perform operations in this order:

1. Instantiate the message with type and code.
2. Add a token.
3. Add options from the option with lower OptionNumber to the higher one.
4. Lastly, add a payload.

Note

Message building does not require to initialise the CoAP node.
