CC2531: Issue With Network Leave While Using Z-Stack Mesh 1.0.0

Part Number: CC2531
Other Parts Discussed in Thread: Z-STACK

Hello,

I am currently running Z-Stack Mesh 1.0.0 on two CC2531 USB dongles, one configured as Co-Ordinator and other as an End Device. Post association and a data transfer from End Device to Co-Ordinator, I am issuing a Network Leave command from the Co-Ordinator to the End-Device calling the following API on a key press.

uint8 IEEEAddr[Z_EXTADDR_LEN];

APSME_LookupExtAddr(dstAddr.addr.shortAddr, IEEEAddr);

status = ZDP_MgmtLeaveReq(&dstAddr, IEEEAddr, TRUE, FALSE, FALSE);

Also, I have verified the destination short address and the IEEE Extended Address.

Though the "status" is reflected as SUCCESS, using a sniffer, I am unable to see any DATA packet OTA. Please advise.

Thanking You,

Abhay

What's polling rate of you end device?

It is currently set to 10^6 milliseconds

It means 1000 seconds, right? If so, the polling is too long and leave command won't be polled.

Thanks Chen,

I was able to view the packet OTA when the polling rate was reduced. Also, I was able to get the leave response from the end device with cluster ID 0x8034 in the form of a data packet.

Post leave, the MAC is constantly polling for data from the co-ordinator. Hence, I assume that MAC is still in the associated state even after Network Leave. Is this expected behavior?

Do you send leave request with rejoin flag=0?

0 Abhay Joshi over 8 years ago in reply to YiKai Chen

Intellectual 810 points

Yes, The rejoin flag is set to 0.

If the rejoin flag is 0, device should leave and cannot do any polling. Can you attach your sniffer log to show me this issue?

The device responds not support leave command.

Hello Chen,

I have enabled MT_ZDO_MGMT for the end device following which it has stopped polling the parent post network leave. What is the status of the MAC? When does the MAC Disassociation Feature come into picture?

When you use MGMT leave, there’s no MAC deassociation .
