Simulating 6LoWPAN network in COOJA #1558

Closed svnesbo closed 8 years ago

svnesbo commented 8 years ago

Hi,

I have some CC2650/CC1310 code that I want to simulate in a large mesh network, so I have adapted the code for COOJA since there is no native CC2650/CC1310 mote type.

The code compiles but when I simulate I can't seem to get the motes to talk to one another. I have shaved away most of the code so I'm left with a minimal example, which I have attached. For my application I am interested knowing about the neighboring nodes, so the code prints out the neighbor table when the button is pressed.

I've tried compiling this code with make cooja-test.cooja TARGET=cooja I've tried with a variety of settings for NETSTACK_CONF_RADIO/FRAMER/RDC etc. with no luck. I've also tried compiling for cooja-ip64, but that didn't work either.

This is the output from the motes when they start: 899 ID:3 Contiki-3.x-2220-g8f9ff51 started. Node id is set to 3. 899 ID:3 Rime started with address 0.3.0.3.0.3.0.3 899 ID:3 MAC 00:03:00:03:00:03:00:03 sicslowpan/CSMA/nullrdc, channel check rate 1000 Hz 899 ID:3 Tentative link-local IPv6 address fe80:0000:0000:0000:0203:0003:0003:0003 899 ID:3 Tentative global IPv6 address fd00:0000:0000:0000:0203:0003:0003:0003 899 ID:3 Starting 'Cooja Test - Main Process' 1024 ID:3 Got network connection.

If I push the button on one of the motes, I get this (no neighbors are printed, ie. there are none): 3601239 ID:2 Button pressed 3601239 ID:2 My IP: 100:fd00::202:2:2 3601239 ID:2 Neighbor table:

The radio messages window shows that the motes are sending ICMPv6 RPL DIS messages, but nothing else. Here are some example messages: 6001238 2 1,3,4,5 27: 15.4 D 00:02:00:02:00:02:00:02 0xFFFF|IPHC|IPv6|ICMPv6 RPL DIS|0000 6001717 5 1,2,3,4 27: 15.4 D 00:05:00:05:00:05:00:05 0xFFFF|IPHC|IPv6|ICMPv6 RPL DIS|0000

Can someone please help me get this working? I'm using contiki commit ID 3.x-2220-g8f9ff51, with no local changes.
