Jukka Rissanen bd3908b2a9 net: nbuf: Add timeout to net_buf getters This commit changes the net_buf getter functions in nbuf.h by adding a timeout parameter. These function prototypes are changed to accept a timeout parameter. net_nbuf_get_rx() net_nbuf_get_tx() net_nbuf_get_data() net_nbuf_get_reserve_rx() net_nbuf_get_reserve_tx() net_nbuf_get_reserve_data() net_nbuf_copy() net_nbuf_copy_all() net_nbuf_push() net_nbuf_append() net_nbuf_write() net_nbuf_insert() Following convinience functions have not been changed net_nbuf_append_u8 net_nbuf_append_be16 net_nbuf_append_be32 net_nbuf_insert_u8 net_nbuf_insert_be16 net_nbuf_insert_be32 net_nbuf_write_u8 net_nbuf_write_be16 net_nbuf_write_be32 so they call the base function using K_FOREVER. Use the base function if you want to have a timeout when net_buf is allocated.

CoAP over DTLS sample client
############################

Overview
********
This sample code shows a CoAP over DTLS client using mbedTLS on top of Zephyr.

Building and Running
********************

Follow the steps for testing :ref:`networking with Qemu <networking_with_qemu>`.

Run the server application at samples/net/coaps_server, with the following
command:

.. code-block:: console

	make server

In other terminal window, run this client application at samples/net/coaps_client:

.. code-block:: console

	make client

You will get the following output:

.. code-block:: console

	reply: 60 45 00 01 ff 54 79 70 65 3a 20 30 0a 43 6f 64 65 3a 20 31 0a 4d
	49 44 3a 20 31 0a 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

	00 00 00 00 00 (123 bytes)

From the server application directory the screen should display

.. code-block:: console

	*******
	type: 0 code 1 id 1
	*******
	connection was closed gracefully
	done

If the server does not receive the  messages, restart the app and try to connect
the client again.
