# HOWTO - Setting up the RPL Border router and other nodes
|
|
|
|
In this folder we have a fully functional demonstrator with the components:
|
|
|
|
1. **RPL border router**: to start the wireless network and connect it to other networks.
|
|
2. 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**
|
|
```C
|
|
#define UART_HW_FLOW_CTRL 1
|
|
#define UART_XONXOFF_FLOW_CTRL 0
|
|
```
|
|
* or **SW flow control**
|
|
```C
|
|
#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.
