Unable to send to a specific multicast address when sending UDP messages in OpenThread CLI sample

RE: Unable to send to a specific multicast address when sending UDP messages in OpenThread CLI sample

Hi Marte,

I've understood the situation.
If I still have questions about this issue after the other ticket has been resolved, I will contact here later.

Best regards,

Yuma

Hi Yuma,

The way I understood it, the issue is that you are not able to send UDP messages to certain addresses unless Thread is enabled, which is expected. However, for some reason messages that are received are not printed to log unless Thread is disabled (as you reported in the other ticket). Based on this, it seems like the only problem is the latter, and that things should work as expected if that problem is solved.
Please let me know if there is something I missed.

Best regards,
Marte

Hi Marte,

I see.
Am I correct in my understanding that this ticket will be put on hold until the issue Maria is working on is resolved?

Best regards,

Yuma

Hi Yuma,

Maria will handle the UDP messages not being displayed issue in your other ticket.

Hi Yuma,

I will look into the issue about the UDP message not being displayed.

Hi Marte,

Thank you for your advice.

I attached to a Thread network and tried again.
Then, the sniffer log was displayed in Wireshark, but the reception log was not displayed on the other device.

Regarding the issue of UDP message reception logs not being displayed, we are currently inquiring through the following ticket, but we are facing an issue where the reception logs will not be displayed unless the thread protocol is disabled.

Hi Yuma,

You need to run ot thread start to enable the Thread protocol and attach to a Thread network.

Each board sended UDP message to FF04::3:0, but the message was not received another one.
At the time, on wireshark, this messages was not show.
(When the board sent UDP message to FF02::1, the sniffer log showed on wireshark.)

I don't have any filters in wireshark.

Best regards,

Yuma

Hi Yuma,

I tested this on my side and the UDP messages showed up in the sniffer log when sending to FF03::1 and FF04::3:0. The message sent to the mesh-local address, FF03::1, was printed on the receiving node as well.

Can you share all the CLI commands you are using when testing?
Do you have any filters in Wireshark?

Best regards,
Marte

Hi Yuma,

I have started looking into this and will come back to you tomorrow.
