CC2530: NLME_LeaveReq() failing from the Second time

Babu P S

Part Number: CC2530

Calling NLME_LeaveReq() first time succeeds (After Firmware flash)
After wards it fails with Response of 0xC2 (ZNwkInvalidRequest). even though the device (that needs to leave) exist in the Network.
I don't see why the request is invalid,

I am calling NLME_LeaveReq() this way, inside a function(devExtAddrs & Rejoin are passed to the function).

NLME_LeaveReq_t *leavereq = (NLME_LeaveReq_t*)osal_mem_alloc(sizeof(NLME_LeaveReq_t));
leavereq->extAddr = devExtAddrs;  
leavereq->removeChildren = FALSE;
leavereq->rejoin = Rejoin;
leavereq->silent = FALSE;
NLME_ResponseCapture = NLME_LeaveReq((NLME_LeaveReq_t*) leavereq);  
osal_mem_free((NLME_LeaveReq_t*)leavereq); //free

The Response is captured in the NLME_ResponseCapture which showed up 0xC2.
Could someone help with a solution.

Do you have a log showing the node leaving and rejoining? ZNwkInvalidRequest is very likely to happen because the node is not in the network, you might want to check _NIB.nwkState before sending the leave command just to be sure.

Thanks Dalila for the response,

Do you have a log showing the node leaving and rejoining?

Yes, I do. (From the protocol Analyzer). This happens only after the fresh firmware flash. after which ZC doesn't send Leave Command and ends up in the Response 0xC2.

the node is not in the network,

The Device is still latched on to the network (figured out from the protocol Analyzer).

check _NIB.nwkState before sending the leave command

The state at the ZC for _NIB.nwkState = NWK_ROUTER.

Do you mean you send NLME_LeaveReq from ZC?

If you want to ask a device to leave network from ZC, you should use API ZDP_MgmtLeaveReq

To use ZDP_MgmtLeaveReq() API, doesn't ZED/ZR should have the "ZDO_MGMT_LEAVE_REQUEST" compile flag with it ?
For a ZED/ZR (lets say 3rd party) that has joined my network when opened, should be removed from the network where it is not supposed to.
Then ZDP_MgmtLeaveReq() will not work. Isn't it ? (Considering that device has no "ZDO_MGMT_LEAVE_REQUEST" flag compiled into it).

As I know, ZDP_MgmtLeaveReq should work even sending to 3rd party device.
