CC2652R: zstackmsg callback (HDR_Event) for device leaving network

Hamza Kadhum

Part Number: CC2652R

Hi,

I'm wondering if there is a callback command similar to zstackmsg_CmdIDs_ZDO_LEAVE_IND but instead for devices disconnecting or leaving the network without the coordinator requesting zstack_zdoMgmLeaveReq,

I want to update the network key as the network detect there is a device that has left the network.

Best regards,
Hamza

As I know, there is no such mechanism. If you worry about network key leakage, maybe you can try to update network key periodically such as every 24 hours.

Hi,

Is there an API to look up how many devices are in the network?

No, there is no such API. I would suggest you to keep a device list on coordinator in your own application.
