Original question:

CC2530: Notification when device is lost from the network

CC2530: The terminal nodes cannot rejoin the network, Z-Stack 3.0.2

Part Number: CC2530
Other Parts Discussed in Thread: Z-STACK,

Hi Teams,

I using CC2530 as the Zigbee application development in one of my project, and the Stack version is Z-Stack 3.0.2. There are only coordinators and terminal nodes in the network, and terminal nodes can normally enter the network for communication.

But now I got in some troubles by the following test. When I powered off the coordinator a while and then power it on, the terminal node couldn't reconnect to the network. While I keep the coordinator work normally and powered off the terminal nodes and then power it up, the terminal node also couldn't rejoin the network.

For the Z-Stack 3.0.2 provided by TI website, due to our different hardware design, I removed the UI application program of the protocol Stack and added my own LCD driver, buttons and LED display also made corresponding adjustments. 

Only the application program was changed in the protocol Stack. I added the screenshot of program grabs to the below.

Thanks,

Best Regards

    Hi Lumina,

    Please provide the full sniffer log file next time.  This is not typical Z-Stack 3.0.2 application behavior.  My first thought is that this is an issue with NV memory.  Do you keep NV_INIT and NV_RESTORE defined in your application and does it ever complete a factory reset with bdb_resetLocalAction?  Is it able to join the network normally if you enable joining on the coordinator again?  Are any changes made to the network settings or do they only apply to your hardware changes?  You should further debug your CC2530 project and can also refer to the Known Issues E2E page.

    Regards,
