CC2652R: ZED can't join zigbee network

Do you use sniffer to check what exactly happens over the air?

No,I have no sniffer to use.

It's difficult to judge what happens without sniffer log so I strongly suggest you to setup sniffer to check what exactly happens over the air.

I agree with YK, sniffer logs are required to verify the behavior you are describing.  The ZEDs should be able to join the ZC at any time its network is open.  You would need to call APP_CNF_BDB_START_COMMISSIONING again from the MT API if using ZNP configurations, as zdoStartCommissioning is an application-level API. What happens when you reset your ZEDs? 2.7.1 is outdated Z-Tool versioning and Z-Stack 3.0.2 is the CC253X Zigbee stack which is different from the SIMPLELINK-CC13X2-26X2-SDK.

Thanks for your reply!

When ZEDs back to DEV_HOLD state,I called APP_CNF_BDB_START_COMMISSIONING angin by using MT API:zdoStartCommissioning.

The Z-Stack I used is 4.10.00,I writed wrong.

I will provide sniffer logs later.

Thank you!

Hi!

These days,I got a LAUNCHXL-CC26X2R1 launchpad,I used it with Smart RF Sniffer and wireshark to get the sniffer logs.

I have acquired normal logs and abnormal logs of ZED join network process.The screenshots of the logs are shown below:(Fig1 is normal process,Fig2 is abnormal process)

Fig1 normal process

Fig2 abnormal process

When ZC started first and then ZED started later,ZED join process is shown in Fig1,ZED can receive key from ZC.

When ZED started first,after a while(several minutes later),ZC started,ZED can't join the network,this abnormal process is shown in Fig2.

Fig2 shows perhaps ZED can't wait to rececive key which transmited by ZC,then ZED broadcasted beacon request again.ZED repeated join network,and repeated this abnormal process over and over.

In addition,I discovered that when I set primary channels to only one,for example,set primary channel to 16,and not set secondary channels in the file:znp.syscfg in my ZNP project,ZED can join at any time when network is open.But,when I set both primary channels and secondary channels to multiple as shown in Fig3(I set primary channels to 11,13,16,20,25,and set secondary channels to 14,18,19,21,23,24,26),the abnormal process will happen as I have described.Before,I have always set primary and secondary channels to multiple.

Fig3 channels setting

I want to know whether different settings of channels affect ZED join network.

Thank you very much!

Hi!

I have provided sniffer logs,please refer to the reply I sent to YiKai Chen.

Thank you very much!

Please provide sniffer log files instead of screenshot.

Hi!

I insert sniffer log files,but I cann't submit successfully.This E2E forum prompt error as the screenshot shown.

I have tried several times,it's always prompt error.

Would you please give me a mailbox,I send sniffer log files to you?

Thank you very much!

Try to zip your log first and attach again.

There have been some improvements made to the ZNP ZED configuration in the SIMPLELINK-CC13X2-26X2-SDK v4.40 (see the Z-Stack Release Notes from the Documentation Overview) so I recommend evaluating with the latest SDK version.  Currently you could also mitigate the issue by forcing a factory reset before starting another join attempt.

Hi!

I provide zip file of sniffer logs.

Thanks!0488.sniffer log.zip

I will reference v4.40.

Thanks!

I cannot open your sniffer correctly. Which WireShark version do you use?

The wireshark version I used is 3.0.0

Hi!

Thank you for your reply!

I updated ZNP to verion 4.40,now this problem can be solved.

Thanks!
