Overview

Supported Features

The networking stack supports the following features:

• IPv6
  • IPv6 header compression, which is part of the 6LoWPAN support
• UDP
• IPv4
  • DHCP client support for IPv4
• IPv6 and IPv4 are supported at the same time.
• TCP
  • Both client and server roles are supported
• RPL (Ripple) IPv6 mesh routing

• Highly configurable
  • Features, buffer sizes/counts, stack sizes, etc.

Additionally these network technologies are supported:

• IEEE 802.15.4
• Bluetooth
• Ethernet
• SLIP (for testing with Qemu)

Source Tree Layout

The IP stack source code tree is organized as follows:

subsys/net/ip/

This is where the IP stack code is located.

include/net/

Public API header files. These are the header files applications need to include to use IP networking functionality.

samples/net/

Sample networking code. This is a good reference to get started with network application development.

tests/net/

Test applications. These applications are used to verify the functionality of the IP stack, but are not the best source for sample code (see samples/net instead).
