| + | |||
| + | Ok, now it's built. Let's bring up the slip interface on Linux. Note that the baud rate here has to match the baud rate in the uart setup on the board, which is currently 38400. That's a little slow, but I'll work on bringing it up in future revisions. Also note the " | ||

| + | |||
| + | It's helpful that tunslip6 is putting through the debug messages from the Sparrow. So we can see the boot-up process complete successfully. | ||

| + | ===== Ping ===== | ||

| + | |||
| + | ===== Nodes Beyond the Border ===== | ||
| + | |||
| + | We want to reach more nodes than just the one connected. So let's add a route on the host PC. This "route add" command tells Ubuntu that whenever it wants to reach a node whose IP starts with fdfd::/64, it can send that through the tun0 interface. | ||
| + | |||
| + | < | ||
| + | $ sudo route -A inet6 add fdfd::/64 dev tun0 | ||
| + | $ netstat -r6 Kernel IPv6 routing table | ||
| + | Destination | ||
| + | aaaa::/ | ||
| + | fdfd::/ | ||
| + | |||
| + | Now that we have the route set up, we can put another node on the network, and ping that. | ||
| + | |||
| + | Put anything that speaks RPL on fdfd::1, for example rpl-collect/ | ||
| + | |||
| + | < | ||
| + | $ make TARGET=sparrow savetarget | ||
| + | $ make udp-sender.sparrow.u AVRDUDE_PORT=/ | ||
| + | |||
| + | Now see that we can ping it ok: | ||
| + | |||
| + | < | ||
| + | 64 bytes from fdfd::1: icmp_seq=1 ttl=64 time=67.8 ms | ||
| + | 64 bytes from fdfd::1: icmp_seq=2 ttl=64 time=66.3 ms</ | ||
| + | |||
| + | ====== Using the Webserver ====== | ||
| + | |||
| + | From a PC on our network, we want to view a web page served up by any node on our wireless IP network. This will allow us to look at sensor values or other data stored there. | ||
| + | |||
| + | ===== Building ===== | ||
| + | |||
| + | We'll put the rpl-border-router (with no webserver) on the node connected to the PC, and talk SLIP over USB between it and the PC. The other node will run webserver-ipv6 with ' | ||
| + | |||
| + | < | ||
| + | $ make TARGET=sparrow savetarget | ||
| + | $ make upload WITH_WEBSERVER=0 WITH_SLIP=1 AVRDUDE_PORT=/ | ||
| + | $ cd examples/ | ||
| + | $ make TARGET=sparrow savetarget | ||
| + | $ make WITH_WEBSERVER=webserver-nano -j10 | ||
| + | $ make upload login WITH_WEBSERVER=webserver-nano AVRDUDE_PORT=/ | ||
| + | |||
| + | ===== Running ===== | ||
| + | |||
| + | This has to be done in another window, because "make login" above took over that window. Here we will bring up the tunnel, and try everything out, one thing at a time. Ping the router, ping the webserver, do the ' | ||
| + | |||
| + | < | ||
| + | $ sudo route -A inet6 add fdfd::/64 dev tun0 | ||
| + | $ ping6 fdfd::3 $ ping6 fdfd:: | ||
