CC2650EMK: About BACKOFF state time

There is no new version for CC2650 after Z-Stack Home 1.2.2a. Do you see this on original Z-Stack example such as Sample Switch?

Thank you for your reply.

I don't have CC2650EMK.

So, I cannot run original Z-Stack example.

When I set up a thread, I set the Part Number to CC2650, but I couldn't write to the ZIgbee forum, so I wrote it with CC2650EMK.

Is there anything I can do?

Best Regards,

Yuya Murata

You can debug and trace into backoff related code to see if the backoff timer event is set properly first.

Thank you for your reply.

Is the backoff timer event the ZDApp_event_loop function in ZDApp.c?

That code has not changed from the code provided.

My problem is that sometimes I get a Beacon Request after 5 minutes and sometimes I get a Beacon Request after 10 minutes.

Please see the following screen shot.

Best Regards,

Is it possible that there is interference on this channel so the beacon request is missed?

Nothing.

The distance is about 10 cm between end device and CC2531 dongle.
and that situation is happen many times.

I have a long packet log, how can I attach it?

You can zip the log and drag&drop it into edit box to attach it. I don't think it would be useful to check sniffer log for this issue. You might need to trace code to see if the backoff timer event is set properly first.

Hello Yuya,

There has been a history of similar issues for this device and stack version, I suggest that you review these prior E2E threads:
