Not able to start 6LBR on BeagleBone Green Wireless Edge Router.

Supriya Somashekar

Other Parts Discussed in Thread: CC2650, CC2531, CC2650STK

Hi,

I am trying to build an Edge Router with a SLIP radio using TI Sensortag CC2650 and 6LBR installed on BeagleBone Green Wireless to connect to a 6LoWPAN Network.

I have flashed the sensortag as SLIP Radio and installed 6LBR on to my BBG Wireless following the steps mentioned in the link https://github.com/cetic/6lbr/wiki/Other-Linux-Software-Configuration and on http://processors.wiki.ti.com/index.php/Cc26xx_sw_examples. When I start 6LBR on BBG, service will be started but the webpage https://[bbbb::100] is not opening. When I checked the log file 6lbr.log I found that 6lbr service and slip radio are starting and MAC address of the Slip Radio is been fetched but later on, it is failing due to a fatal error: "FATAL: TAP: ioctl() : No such device". Contents of my log file is as below:

I didn't find much help on the issue on google.

It would be of great help if I can get guidance on this.

Thanks in Advance...!!!

When you connect CC2650 SensorTag Tk BBG, does it emulate ttyACM0?

Hi,

Sorry for a late reply.
Yeah...It does...my SLIP Radio is been recognized on ttyACM0.

Try to follow the steps in sunmaysky.blogspot.tw/.../setup-6lbr-to-run-6lowpan-with-cc2531.html to setup your 6lbr. Basically, the steps for Raspberry Pi and BeagleBone are similar.

Thanks a lot Chen.

Will try this and get back.

Hi Chen,
I followed the steps on the website that you had mentioned.

But now, 6lbr.log file is not getting created neither I am able to access the web page [bbbb::100]. Since the log file is not created I am not able to understand what is happening.

Please, Please help me out with this.

Thanks and Regards,

What do you use as slip radio to connect to your BeagleBone?

0 Supriya Somashekar over 10 years ago in reply to YiKai Chen

Prodigy 225 points

I am using CC2531 Dongle as RF Interface.

0 YiKai Chen over 10 years ago in reply to Supriya Somashekar

Guru 735695 points

When you connect CC2531 dongle to BeagleBone, do you see ttyACM0 enumerated under "/dev"

0 Supriya Somashekar over 10 years ago in reply to YiKai Chen

Prodigy 225 points

I ran "dmesg" and got ttyACM0. But I didn't check under /dev. I will check that too.

0 YiKai Chen over 10 years ago in reply to Supriya Somashekar

Guru 735695 points

Make sure you have ttyACM0 enumerated when CC2531 dongle is plug into BeagleBone. By the way, do you download processors.wiki.ti.com/.../Cc2531-slip-radio_contikimac.zip to your CC2531 dongle?

0 Supriya Somashekar over 10 years ago in reply to YiKai Chen

Prodigy 225 points

I have downloaded contikimac hex file on to it.

0 YiKai Chen over 10 years ago in reply to Supriya Somashekar

Guru 735695 points

Then, make sure you see ttyACM0 is enumerated.

0 Supriya Somashekar over 10 years ago in reply to YiKai Chen

Prodigy 225 points

Hi Chen,

I reinstalled the 6lbr application and now I am getting my log file and I also check for ttyACM0 under /dev, CC2531 is enumerated.

But I am still not able to successfully launch the application. Below are few details:

/dev

lsusb

sudo lsusb -v

ifconfig

6lbr.log

6lbr.err

nvm.dat file

Please guide me further.

Thanks and Regards,

You use Ethernet cable or WiFi to connect to network. Which one do you use?

0 Supriya Somashekar over 10 years ago in reply to YiKai Chen

Prodigy 225 points

I use Wifi .

0 YiKai Chen over 10 years ago in reply to Supriya Somashekar

Try to use Ethernet cable to connect and test again.

0 Supriya Somashekar over 10 years ago in reply to YiKai Chen

I will try that and will get back to you with the results Chen.

0 YiKai Chen over 10 years ago in reply to Supriya Somashekar

Sure and hope it works with Ethernet cable.

Hello Chen,
6LoWPAN Border Router is working now :)
I was using BeagleBone Green Wireless and this didn't have a LAN port, I ordered for the adapter and I had Raspberry Pi 3, so I tried it on that and connected it to the Ethernet instead on Wifi and it worked:) :) I am able to get the webpage now and 6lbr.ip file is created.
Thanks a ton for your support and guidance Chen.

Hi Chen,

6LBR default page is opening and through that I am able to read the sensor data as well, But I am not able to connect to IBM Quickstart.

Please help me out with this.

Do you enable NAT64 on 6lbr?

0 Supriya Somashekar over 9 years ago in reply to YiKai Chen

Prodigy 225 points

I have installed wrapsix...and starting it...it says its starting that's all.
How do I enable it...? Am I on the right path...?

0 YiKai Chen over 9 years ago in reply to Supriya Somashekar

Guru 735695 points

Do you do the following steps after you start wrapsix? Especially those red lines?

Note that route must be manually added.

Please see https://github.com/cetic/6lbr/wiki and https://github.com/cetic/6lbr/wiki/6LBR-Connection for more information.

Make sure that 6lbr is running on BBB by going to its web interface in a browser connected to the same Access Point enter [bbbb::100] in your browser, this will present a webserver to you. You can get the IPv6 address of the 6lbr (edge router) by cat /var/log/6lbr.ip using e.g. putty on your BBB.
You need to set the default route for packets from the 6lowpan network, you do this from the 6lbr's web interface by:
Go to [bbbb::100] using a browser
Click "Config" in the menu
Find the IPv6 address of e.g. your PC (6lbr hands out IPv6 addresses to all devices connected to the same subnet, e.g. your PC should have one with prefix bbbb::)

It is important that it a real IPv6 address and that the IPv6 address belongs to a device on the subnet and that the device is turned on. If the device is not reachable, the connection to Internet will go down. It is not possible to use the BBB IP address for this.

Enter e.g. your PC or access point IPv6 address in the "Peer router" edit box.
Scroll down and click Submit button. The Edge Router application will reboot and are then ready for use.

Note! See this link on connecting to the Edge Router (6lbr) for Linux and Mac OS X there are some IPv6 modifications needed.

Your Edge Router is now fully configured for use locally with IPv6 and with Internet using IPv4 via NAT64.

Hi Chen,

Thanks a lot for your quick reply.

NAT64 is enabled on my Edge Router and I entered the IPv6 address of my PC to which my edge router is connected to as the "Peer Router" but nothing is still working.

Below is the my configuration page.

Where am I going wrong...? Also I am not sure on my understanding on NAT64 and 6LBR.

Try to run tcpdump on BBBG to see if anything is sent out on port 1883

tcpdump –X –v –i eth0 port 1883

0 Supriya Somashekar over 9 years ago in reply to YiKai Chen

Getting an error.
tcpdump: illegal token: –

0 YiKai Chen over 9 years ago in reply to Supriya Somashekar

Try to do "sudo tcpdump –X –v –i eth0 port 1883".

0 Supriya Somashekar over 9 years ago in reply to YiKai Chen

Yeah tried with sudo itself.

Doesn't it work?

0 Supriya Somashekar over 9 years ago in reply to YiKai Chen

No it didn't work at the beginning but now it did.

0 YiKai Chen over 9 years ago in reply to Supriya Somashekar

Guru 735695 points

So, there is no MQTT packets send out from your BBG. CC2650STK should sends out MQTT packets to BBG every 30 seconds by default and it would blink LED when sending MQTT packets. Do you see LED blinking every 30 seconds? I also suggest you to setup Contiki 6LowPAN sniffer to check if MQTT packets are sent out from CC2650STK first.

0 Supriya Somashekar over 9 years ago in reply to YiKai Chen

Prodigy 225 points

Hi Chen,
No my sensortag LED is not blinking so MQTT packets are not sent out on Port 1883 and I will install the sniffer and check for the confirmation. But how can I go about this if MQTT packets are not sent...?

Can you check what UART output from CC2650STK when you start cc26xx-web-demo?

0 Supriya Somashekar over 9 years ago in reply to YiKai Chen

Prodigy 225 points

Chen, How do I check UART output..?

0 YiKai Chen over 9 years ago in reply to Supriya Somashekar

Guru 735695 points

You can connect DEVPACK_DEBUGGER to your PC and open teraterm on the virtual COM port that simulated by DEVPACK _DEBUGGER. Then, connect your CC2650STK and you should get UART output from CC2650STK.

I downloaded TeraTerm and selected the Serial option and selected the XDS110 Uart option and then connected my sensortag to the devpack but I am not getting any output on the console.

0 YiKai Chen over 9 years ago in reply to Supriya Somashekar

Guru 735695 points

There are two virtual COM port simulated by DevPack. Which one do you use and What Baudrate do you use?
