Hello,

I followed the information from here: http://processors.wiki.ti.com/index.php/Cc26xx_sw_examples

I cannot ping 6lowpan nodes. also i cannot connect to webserver [bbbb:100]

debian@beaglebone:~$ sudo ping6 aaaa::101
PING aaaa::101(aaaa::101) 56 data bytes
From bbbb::101 icmp_seq=1 Destination unreachable: Address unreachable
From bbbb::101 icmp_seq=2 Destination unreachable: Address unreachable

Ping the beaglebone from same network pc:

C:\Users\user>ping -6 bbbb::101

Pinging bbbb::101 with 32 bytes of data:
PING: transmit failed. General failure.
PING: transmit failed. General failure.
PING: transmit failed. General failure.
PING: transmit failed. General failure.

I get lot of "PF: No input function set" warns in log.

    Do you have a node with IP [bbbb::101]?

    yes is ok if i ping bbbb::101 from beaglebone, but cannot from outsite

    debian@beaglebone:~$ sudo ping6 bbbb::101
    PING bbbb::101(bbbb::101) 56 data bytes
    64 bytes from bbbb::101: icmp_seq=1 ttl=64 time=0.596 ms
    64 bytes from bbbb::101: icmp_seq=2 ttl=64 time=0.211 ms
    64 bytes from bbbb::101: icmp_seq=3 ttl=64 time=0.209 ms
    64 bytes from bbbb::101: icmp_seq=4 ttl=64 time=0.209 ms

    bbbb::101 is beaglebone linux server

    I don't think bbbb::101 can be ping from outside. You should use actual IPv6 address for ping.

    On any PC connected to the same eth segment as the BBB
    ping6 aaaa::<address of mesh node>

    It sais in wiki, also i cannot connect to bealgebone 6lbr webserver

    I found a video on youtube: https://www.youtube.com/watch?v=dYB-NKwt408 

    Here the ifconfig looks different, and the webserver works. But i dont know what configuration of network/interfaces and 6lbr.conf did he used.

    Do you connect all these BBB and your PC to an IPv6 enable router?
  • 0 in reply to YiKai Chen
    Intellectual 360 points

    No, how to do this? Ive done this but same problem

    sudo ip -6 addr add bbbb::101/64 dev eth0
    
sudo route -A inet6 add aaaa::/64 gw bbbb::100
  • 0 in reply to magnerep
    Guru 735455 points
    You have to find an router with IPv6 capability and connect all of your test device to it.
  • 0 in reply to YiKai Chen
    Intellectual 360 points

    Are these:

    sudo ip -6 addr add bbbb::101/64 dev eth0

    route -A inet6 add aaaa::/64 gw bbbb::100

    and

    sysctl -w net.ipv6.conf.eth0.accept_ra=1
    sysctl -w net.ipv6.conf.eth0.accept_ra_rt_info_max_plen=64

    Needed anymore? As i cannot find them in your tutorial.

    Do you connect your BBB to an IPv6 enable router?
  • 0 in reply to YiKai Chen
    Intellectual 360 points

    No, it is a ipv4 router. BBB has ipv4 on eth0 from ipv4 router and tap0 is a interface with ipv6 dhcp generated in beaglebone with RADVD as it sais in the tutorial.

  • 0 in reply to magnerep
    Guru 735455 points
    You have to connect BBB and your PC to a IPv6 enable router and you can use [bbbb::100] to access 6lbr web page from browser on PC.

    But the second method, using ipv4 network? Cannot be done?

    Second method? Since you are testing on 6LowPAN, you have to use an IPv6 enable router.

    Hello magnerep,

       Were you able to find why it kept fetching the MAC address? I am using the same hardware. Thank you in advance.

    It usually is caused by something wrong on your slip radio. What HW do you use as Slip radio?

    For the slip radio I am using the CC1310 launchpad with a CP2102 UART/USB dongle to interface with the BBB. I separately tested this slip radio to see that it was talking and I got the following:

    So I think that means that the slip radio is talking. But when I look at the .log file after running the 6lbr service I see the following and cannot access the [bbbb::100]

    Is the problem with the slip radio? I have followed the directions for the CC13xx launchpad flashing so I'm not sure where it's going wrong.

    If you use LAUNCHXL-CC1310 as slip radio, you can connect it to your host by usb micro socket on launchPad directly and no need for CP2102.
