CC2652R: ZED cannot rejoin coordinator after power cycle

Walter Macamos

Part Number: CC2652R

Hi TI Team,

The battery powered ZED with (poll rate =0) commissioning is OK. But after power-cycle sends the rejoin request to the coordinator but never gets rejoin response. Please see below screen shoot. The ZED source address is 0x4723. I have also attached the sniffer log for your analysis.

Hi Walter,

Your ZC's network buffers are most likely being overloaded alongside discarding undesired packets on an extremely noisy Zigbee channel, resulting in no response to the Rejoin Request. Have you implemented the fix previously discussed? https://e2e.ti.com/support/wireless-connectivity/zigbee-and-thread/f/158/p/883559/3274286#3274286

At some point the ZC appears to become dysfunctional as all it does is send Leave Requests.

Regards,
Ryan

Hi Ryan,

Thanks.

We have not implemented your suggestion 1-3. We will do it quickly and see if problem is resolved.

The question is we experience this problem even if there is only one trying to rejoin.

Regards,

Walter

Hi Walter,

The channel being tested on appears quite noise and I would recommend you switch to a quieter one if possible.

Ryan
