CC2530: Rejoin problem

Part Number: CC2530

Hi Team,

Chip: CC2530

ZSTACK: ZHA 1.2.2a

Network structure: one ZC, one ZED

Problem description:

1.Powered down ZC and woke up ZED, ZED would send Orphan Notification and back to sleep. [please check the row 4~26 in ubiqua]

2.Powered down ZC and woke up ZED in a few minutes, ZED would send beacon request and back to sleep. [Row 237]

3.Powered down ZC and kept it a long time[half an hour to a couple of hours], then woke up ZED. ZED sent data request and could not rejoin the network when powered on ZC. Only reset the ZED could work. [Row 601]

Question:

1.When powered down the ZC for a long time, why would ZED send data request?

2.ZED could not restore network with data request, is there any other operation except reset?

Please check the ubiqua data here: rejoin problem.zip

    Hi Viki,

    I'm not sure why the ZED is sending Data Requests (instead of Beacon Requsts) 16 minutes after the last activity.  Can this be replicated with out-of-box TI examples?  Please make sure NV_RESTORE is defined and debug ZDApp.c to determine the device state and action.

    Regards,
