HOWTO - Setting up the RPL Border router and other nodes
In this folder we have a fully functional demonstrator with the components:
- RPL border router: to start the wireless network and connect it to other networks.
- and a wireless node that acts as a basic RPL node by default (but can optionally be used configured as DAG Root)
RICH RPL Border Router
Setup the UART flow-control mode for the router from border-router/project-conf.h
- Enable either HW flow control
#define UART_HW_FLOW_CTRL 1
#define UART_XONXOFF_FLOW_CTRL 0
- or SW flow control
#define UART_HW_FLOW_CTRL 0
#define UART_XONXOFF_FLOW_CTRL 1
- You can disable both, but it is not recommended.
Compile and flash a node with the rpl-border-router.jn516x.bin image. Either a USB dongle or a dev-board would work.
From a Linux terminal, go to contiki/examples/jn516x/rpl/border-router and do either
make connect-router-hw if you have HW flow control
or make connect-router-sw if you have SW flow control
This will start a tunnel interface (tun0) on the host machine. All traffic towards our network (prefix aaaa::1/64) will now be routed to the border router.
RPL Node
The directory contiki-private/examples/jn516x/rpl/node contains a basic RICH node running TSCH and RPL. You can compile and program more NXP nodes to run this, forming a larger network. You should be able to ping the nodes (you can obtain their IPv6 address either directly from their log output or by enabling DEBUG output in rpl-icmp6.c and looking at DAO prefixes being added.
RPL+CoAP Nodes
coap-*-node are example nodes that expose their sensors as CoAP resources. See README.md files from the sub-directories for more details.
