Part Number: SMARTRF06EBK
Other Parts Discussed in Thread: LAUNCHXL-CC1310

Tool/software: Linux

Hello everyone,

I built lasted 6lbr with Contiki-NG on Raspberrry pi 3B using LAUNCHXL-CC1310 as slip-radio. 6lbr is compiling from the develop branch(commit 728f18f) and contiki-NG is from sixlbr branch of cetic/contiki-ng with commit cd3af6c .I followed the steps from sunmaysky.blogspot.com/.../build-and-run-6lbrcontiki-ng-cc26xx-web.html, but i still cannot access the web page [bbbb::100].The main process is as follows：
1. Change directory to home folder and git clone --recursive github.com/.../6lbr.git
2. Change directory to 6lbr folder and git submodule update --init
3. Change directory to home folder and git clone --recursive github.com/.../contiki-ng.git
4. Change directory to contiki-ng folder and git submodule update --init
5. Change directory to 6lbr/examples/6lbr folder and run the following build command
 "make WITH_CONTIKI=0 WERROR=0 all"
6. sudo make install
7. change to channel 25
8. Create /etc/6lbr/6lbr.conf with the content below
      MODE=ROUTER

      RAW_ETH=1
      BRIDGE=0
      DEV_BRIDGE=br0
      DEV_TAP=tap0
      DEV_ETH=eth0
      RAW_ETH_FCS=0

      DEV_RADIO=/dev/ttyACM0
      BAUDRATE=115200

      LOG_LEVEL=3

9. connect LAUNCHXL-CC1310 running slip radio to Raspberry Pi
10. reboot rpi and start 6lbr service.

the 6lbr.log is:

ps：I repeated the steps above on vmware 15 Pro, everything is ok including accessing web page.

Can anyone tell me how to fix this problem? Thanks very much.

    Your 6lbr.log shows 6lbr starts successfully. When you access to bbbb::100, does the desktop connect to the same router as Raspberry Pi connected to?

    yes, both PC and RPI are connected to the same router.

    If you try to use Chrome to access bbbb::100, can Chrome open the web page?

    page is still unreachable. i am using chrome 70.0.3538.110(32bit).

    i have compiled and built 6lbr on vmware(instant contiki 3.0) with the same process as on rpi . everything is ok, i can access bbbb::100, so i think browser and build process above should be no problem.

    I had tested this on Raspberry Pi running Debian OS instead of Rasbian so maybe you can try to use Debian OS to test again.

    Do you have any proxy settings set in your environment? In other words, what is displayed when echoing the following:

    echo $http_proxy
echo $https_proxy
echo $ftp_proxy
echo $no_proxy

    I reinstalled my rpi system as well as 6lbr, but the problem still exist. I inputed all the commands you mentioned, and the return result of each  command was a blank line.

    Do you try Debian instead of Rasbian on Raspberry Pi?

    I installed pi64-pi(lite version) on rpi3 which is based on Debian Stretch and backed by a 4.11 Linux kernel(github.com/.../pi64). i repeated 6lbr build process, and  i got the same result , page is still unreachable.
    Maybe pi64-pi does not support 6lbr very well. Could You tell me which debian os you are using? thanks.

    here is  6lbr.log

    After checking my record, I had used 2016-05-27-raspbian-jessie-lite.img to test this on my Raspberry Pi.

    I find there is something wrong with latest 6lbr source code so I suggest you try to use “git checkout ff69ae4214407eeec4c71f87589ac4bc7d3a8a49” on 6lbr to test again.

    Could you also post the output of "ifconfig" in your terminal when 6lbr is running?

    Sorry for this late reply. Finally i can access the web page [bbbb::100] with latest 6lbr. i modified my 6lbr.conf and interfaces files following this guild (github.com/.../6LBR-Interface-Configuration). Maybe only bridge mode can work with the latest 6lbr  on rpi3 ?

    Based on my previous configuration,  I did a Wireshark capture on the server and client,  i found that server(bbbb::100) does not  send a SYN/ACK packet after receiving a SYN packet from client during tcp handshake stage, therefor TCP connection cannot be established, Of course,the web page is unreachable.
