Hi, I use Slip-Radio and CC26xx-web-demo. On the server 6lbr I can open the CoAP but not "web" for read the value of MQTT. Why?

Do you do step 10 "Go to Capture -> options -> Manage Interfaces -> New. Input /tmp/sensniff to "Pipe:" and save." in sunmaysky.blogspot.tw/.../how-to-setup-contiki-sniffer-for.html ?

Guru 19990 points

Yes

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

Your screenshot looks different to me. Do you go from wireshark Capture -> options -> Manage Interfaces?

Do you build sensniff and download it into your LAUNCHXL-CC1310 and connecting it to the same desktop running wireshark?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Yes, I followed the steps you sent me. When connecting the CC1310 to the rasp and typing the sensniff steps, it is created perfectly. But with Wireshark I have problems!

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

You should connect LAUNCHXL-CC1310 running sensniff to PC running wireshark instead of connecting it to Raspberry Pi.

Do you connect LAUNCHXL-CC1310 running sensniff to PC running wireshark?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

I connect the CC1310 to the PC, open Wireshark and create the interface / tmp / sensniff. When I start capturing, I have the error I sent you

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

When you plug LAUNCHXL-CC1310 into your desktop, do you see it enum like /dev/tty.usbmodem1421?

It means you don’t build sensnifff successfully. How do you build it?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Download of python.py on Raspberry
On the terminal, sudo python setup.py install
In the path (contiki/ examples/sensniff) I generate the file.bin
I flash the CC1310 sensor
Connect the sensor to Raspberry
Run "python sensniff.py -d /dev/ttyUSB0 -b 46800"
Connect the sensor of the PC, and start Wireshark

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

python.py should be download and run on the Linux system running Wireshark.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Wireshark on my PC or system linux?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

You need to use a Linux Desktop to run python.py and wireshark. You also have to connect LAUNCHXL-CC1310 running sensniff to the Linux Desktop.

Nothing

Can you do a screen capture on running ""python sensniff.py -d ..."?

Guru 735685 points

You shouldn’t be ttyUSB0. It should be like tty.usbmodemxxxx

Where can I read this?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

I had tell you to do “ls /dev”

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

I see only ttyUSB0

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

It means you don’t build and run sensniff on LAUNCHXL-CC1310 correctly.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Ok, it works. Now?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

Check if there’s MQTT messages over the air.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

I not read MQTT protocoll

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

Then, the problem is on device. You have to trace and debug the device side.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

How?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

Do you revise anything in Contiki source code?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

I reinstalled and updated Contiki

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

You don’t revise anything and run default CC26xx-web-demo on LAUNCHXL-CC1310?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Yes

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

If you access to web page of cc26xx-web-demo, do you see http packets shown on wireshark?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Yes I see the package http

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

Can you take a picture on your LAUNCHXL-CC1310 running CC26xx-web-demo and do a screenshot to show me its UART output?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

I see this

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

Can you show me how your picture and screenshot first?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

How about picture of your LAUNCHXL-CC1310 running cc26xx-web-demo?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

This is my device CC1310F128. All function but MQTT not.

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

This obviously isn’t LAUNCHXL-CC1310. You are fooling me...

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

I'm not kidding anyone. I've been working for a year with this CC1310 and everything works. You know it very well! The only thing that does not go is the MQTT. Because? I'm new to Texas development!

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

I ask you in every question that do you run CC26xx-web-demo on LAUNCHXL-CC1310, don’t I?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

You're right, I thought it was the same thing. Sorry friend :(

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Can you help me? Please

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Friend, Please!

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735685 points

I can only suggest you to printf some information in mqtt-client.c to check if your application keeps running.
