Cert_5_1_01_RouterAttach.py Script Execution

[ias my dream]

Hi

I just tried to run the router attach script in python (codelab).

See the execution:

Failure: EXCEPTION: 'module' object has no attribute 'MODE_CCM'

This seems to be because of Makefile-posix build. Let me know if there is any workaround.

Is it possible to configure the MODE_CCM. mode is "rsdn" here.

Script output:

Have you installed the requirements.txt?

pip install -r tests/scripts/thread-cert/requirements.txt

[ias my dream]

May I know the relevance of these variables?

enum34
ipaddress
pexpect
pycryptodome

Thanks

Karthik

[Yakun Xu]

I'm not sure what you means. These are python dependencies for running OpenThread tests. You can install them by:

pip install -r requirements.txt

[ias my dream]

Thanks Yakun Xu.

Hi Yakun Xu,

thank you for the assistance, I have installed the requirements.txt as you suggested and tried to execute the test script again but gave me the below error. 

could you please have a look and let me know any further procedure.

The posix simulator emulates IEEE 802.15.4 radio communication using UDP sockets over loopback. The bind failure indicates that the UDP ports are already opened, probably by other OpenThread processes.

Can you see if there are other `ot-cli-ftd` processes running and, if so, kill all such processes before running the python test scripts again?

Hi Jonathan Hui,

Thank you very much for your help, I have followed the instructions and test scripts are getting executed.

Thank you

Hi,

while executing the scripts few test scripts are failure, I tried to analyze and understand that cause of failure and came to know that every test script that has to execute this line of instruction :

In test
    msg = leader_messages.next_mle_message(mle.CommandType.ADVERTISEMENT)

is causing the whole script failure.

Please could you check the below output and share your comments. thank you.

PFB is my observation for test scripts Router Attach and Leader Reboot.

Do you see a `tmp` directory that contains `*.flash` files where you executed the command from? If so, try removing the directory before running each test.

The `*.flash` files is the settings storage for each simulated node. The tests assume that each simulated device is starting from a factory-reset state.

Hope that helps.

Thank you Jonathan Hui.

As you suggested, I have removed the tmp dir which has *.files and executed the scripts successfully.

scripts are executable. thanks.
