Detailed Description

Examples of advanced message building.

Note

Message building does not require to initialise the CoAP node. See the client example to see how to send the message after building it.

deviceIp()

IPAddress deviceIp	(	192	,

		0	,
		99	)

loop()

void loop

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.
