CC2530: Multiple new device announcements on ZED

Ashwin Natarajan

Part Number: CC2530

Hi folks,

We have a network with multiple (around 15 ZED's and 2 routers) ZED's (running zstack 3.0.1). In our code, we maintain a reboot count variable. This variable is stored in the NV RAM and is incremented at the start of every program cycle (every reboot). We can see multiple device announcements in our controller (ZC) logs, but the reboot count stays the same. Is there any particular reason for the ZED to issue this message multiple times without rebooting?

Thanks,

Ashwin N

If end device loses connection to its parent and rejoin, it will broadcast device announcement. It sounds your end device loses connection to its parent node and rejoin.

Hi Ashwin,

Please provide the sniffer logs if possible. Are there any leave requests or missing MAC ACKs from the ZC?

Regards,
Ryan
