Do we have a method for leaving the nwk and panid when end-device out of coordinator? (Using CC2530 and Zstack 2.5.1a)

Hello everyone. I am Michael,

 

Here is a question about how the end-device to leave the nwk and panid which be saved by NV_RESTORE.

 

If the end-device is connecting with a coordinator, I can use the NLME_LeaveReq to leave the nwk and panid, so it has no problem for the case in connecting.

 

But the end-device out of the coordinator which is connected with it, the end-device will try to join a coordinator. In NV_RESTORE, the end-device can only join the original coordinator. So how can I do for leaving the nwk and panid in this situation?

 

The command of NLME_LeaveReq cannot be used because it must send leave message to the original coordinator. How can I overcome this restriction, or there is other method can let the end-device to leave the nwk and panid in this situation?

 

 

Thanks for reading my question. Please give me some help and advising.

Thanks a lot.

    You can refer to ZDAppCheckForHoldKey in ZDApp_Init(). In ZStack examples, the ZED will clean up NV and start to find a new network if use holds the button and power on device.
