How to make the controller link to sink?

[Gao-k]

Hello,George. I am very interested in the implementation of controller. And I run the project, but I don't know how to make controller link to sink by serial 2 pty. Could you teach me more detailed? Thanks very much!

[georgevio]

Hi, thanks for the interest. Look at file https://github.com/SWNRG/ASSET/blob/master/src/com/uom/georgevio/SerialPortProbe.java it looks for (pseudo) port "/dev/pts/XX" where XX is a number (random?) assigned by cooja. Right-click on the sink, open the serial port, check the port number, and make sure that the SerialPortProbe.java includes the port number into the search. For unknown reasons (maybe Java-related or something) SOMETIMES, it might not work. In such a case, close the ASSET, and open it again. Please, do not hesitate to ask me more things. We can arrange a zoom anytime you wish, Good luck with your endeavors George

Thanks,George.
I do like this:
(1)right click on the sink(contiki-standard-extra-functions/examples/ipv6/rpl-udp-fresh/udp-server.c), Mote tools for Z1 1 -> Serial 2 Pty, then I get the port /dev/pts/4;
(2)in SerialPortProbe.java, I set searchFromNum = 1, searchUpToNum = 11.
(3)Then I run Main.java in Eclipse.
(4)In cooja, I click the start.
(5)In ASSET IDS, I click the start button.
Then I get somethings like this：
Waiting for "Start" button
Starting application...
Thread is RUNNABLE
Opening port: dev/pts/1
Opening port: dev/pts/2
...
Opening port: dev/pts/10
Serial Port not found from pts/1 to pts/11. Sleeping for 3 sec...

How to solve it? Could you give me a hand?

[georgevio]

Good, you are on the right track! Sometimes it does such things, I never had the time to find out why :( Things to do: First run cooja, and then start ASSET If it does not find the port, restart cooja (not ASSET). Try to close the port of the sink, and open it again, sometimes it changes number. Make sure the port is visible and accessible. Before testing it with ASSET, try Linux commands (I don't remember them after all those years...) to make sure you have access to this (pseudo) port. This was ALWAYS the most difficult part for me, how to communicate with the serial port. If you accomplish this, the rest is piece of cake... Btw, I started today some new experiments, so I will deal with contiki/cooja/ASSET again heavily in the next weeks. If I find something or update the code, I will let you know ASAP. Bother me again any time G <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Thank you!
The ASSET folder is under contiki/tools/cooja?
I think I put ASSET in wrong place, where should I put ASSET folder?

[georgevio]

Asset folder is totally irrelevant to Contiki. Put it in your Java projects or else. I suggest NOT to put it inside the contiki folder, you never know what you are going to do there... <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

[Gao-k]

Thank you very much, George!
I have done it. I make a few mistakes earlier.
Looking forward to your new experiments!
Wish you good luck!
But there is still a bug. When I click start, it always produces a red circular node(0) in GraphStream FX, others select it as parent and leave the sink node alone.

[georgevio]

That is new! Are you creating the sink as the first node in cooja? send me a screenshot, or more info, I am very curious <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

[Gao-k]

Yes, I create the sink as first node in cooja, then I add four client.
But in GraphStream FX, you can see following picture.

In ASSET IDS, I don't know why there is 0 node.

[georgevio]

Node 5 is declaring a parent 0. Now this 0 is truncated from IPv6, the last octet. Please, have a look and send me a screenshot of cooja, I want to see the topology and the nodes' outputs. Questions: Are you sending too many UDP packets? Lower it a little bit just to check. What speed are you running the cooja simulation? Change it and again play with it. Are the nodes in cooja within the wireless coverage (be careful with the gray area coverage, it does not usually work)? If you are using different TX/RX and success rates<100% strange things happen Final solution: After I manage to set up my machine (You know Merfy's law, suddenly nothing works, I cannot compile anything, something crazy happened with the msp430-gcc compiler), you can send me the *.csc of cooja, along with the code of the nodes, so I can run it here and see the result. Keep me posted. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

The screenshot of cooja(I run the testing-with-Central.csc in your contiki folder):

I am testing.
Why does node 5 declare the node 0?

[georgevio]

Everything looks good Please, try to close the Serial socket, it is not necessary (do you need it?), the Serial 2 pty is enough. Please, export all logs from cooja (click-edit-select all) and send them to me. along with copying the logs of ASSET. This looks very strange... I have no obvious explanation. Also, try the following: Delete node 5 (maybe it is just a glitch...), add another node (it will be number 6). Does it change things? Change positions of the nodes, while the experiment runs. Wait a few minutes, ASSET should detect the changes and act accordingly altering the topology depicted. Enable the "Print edges info on/off" button of ASSET. Does it change anything? Try a completely different setup from scratch. Try different udp-server/udp-client of the many I have created (Maybe I did something funny with them...) Good work

I try the full-tests folder, it works well.

[georgevio]

Very good! That is what it is supposed to be! Now, about the previous erroneous experiment, maybe it was a glitch, maybe I changed something and didn't test it enough (don't overanalyze it). Continue with the code that actually works... Keep me in the loop for any updates... P.S, Please, do me a favor if you can: write in terminal "gcc-msp430 -v" and tell me the output? I am having problems, I cannot compile any code, I get errors about code not fitting to memory. I remember, years ago, I installed an altered version of the gcc-msp430 compiler, but I don't remember what anymore... :(

Hello, George.
Sorry to bother you again. How to make controller send messages to nodes, such as SP, SN or EI?
