I am doing the cc26xx-web-demo. I tried everything except mqtt quick start.

Only the above picture comes out.

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

6lbr.conf

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

wrapper.c

//+++ CONFIGURATION +++//

#define INTERFACE "eth0"

#define PREFIX"64:ff9b::"

#define IPV4_ADDR "192.168.0.100"

#define HOST_IPV6_ADDR "BBBB::101"

#define HOST_IPV4_ADDR "192.168.0.16"

The above picture shows the result of tcpdump and the ip address of raspberry.

This is what I have set up. I wonder if it is not possible or what I have missed.

If you enable IP64 on your 6lbr, you should stop wrapsix.

How do I stop wrapsix?

0 YiKai Chen over 8 years ago in reply to Hyeonseong ann

Guru 735695 points

Use ps command to list process and kill wrapsix related process.

I have stopped wrapsix, but it still does not work.

0 YiKai Chen over 8 years ago in reply to Hyeonseong ann

Guru 735695 points

Maybe try to disable IP64 on 6lbr and use wrapsix to test again.

I changed the configuration as below but it still does not work.

Try to run "tcpdump –X –v –i eth0 port 1883" on raspberry Pi to see if anything is sent out on port 1883.

Nothing is being sent. When the sensortag is turned on for the first time, it is detected, but after that, nothing is detected.

0 YiKai Chen over 8 years ago in reply to Hyeonseong ann

Guru 735695 points

Do you mean you don’t see it listed on 6lbr sensor page?

0 Hyeonseong ann over 8 years ago in reply to YiKai Chen

Intellectual 720 points

I mean, if i enter tcpdump and turn on the sensor tag, it was sent on port 1883, but it will not be sent anymore after a certain time.

Tcpdump is used for checking MQTT traffic on Raspberry Pi. What do to see on Raspberry Pi terminal if you run tcpdump?

There is no change as above.

Can you do ifconfig to show me the results?

Do ps to make sure your wrapsix is running.

According to one of your screenshot in your original post, it see you use tcpdump and it shows MQTT messages sent to ibm Quickstart. I suggest you to check if any firewall or antivirus SW blocks the traffic.

Intellectual 720 points

Thank you. It was resolved.

0 YiKai Chen over 8 years ago in reply to Hyeonseong ann

Guru 735695 points

Is it caused by firewall or antivirus SW?

0 Hyeonseong ann over 8 years ago in reply to YiKai Chen

Intellectual 720 points

Yes. It works by exiting antivirus SW.

0 YiKai Chen over 8 years ago in reply to Hyeonseong ann

Guru 735695 points

Thanks for confirmation and sharing it back. May I know which antivirus SW blocks the traffic?

0 Hyeonseong ann over 8 years ago in reply to YiKai Chen

Intellectual 720 points

I used "ahnlab safe transaction".

Thanks. It might be helpful if others have similar issue.
