CC2530: Parent lost in ZED!

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

Hello everyone.

I am working with my project based on zstack3.0.1.

When the ZED is connected to the coordinator, the coordinator is powered off and the ZED enters the state PARENT_LOST status.

Then ZED call bdb_ZedAttemptRecoverNwk per 10 seconds,after ZED perform bdb_ZedAttemptRecoverNwk(),it enter power saving status.

Then power consumption of ZED is about 33mA.

Of course,If ZED connect with coordinator,power consumption of ZED is a few uA.

So I did debug my project and ZED wake up in power saving(sleep status) per 10ms often.

I think that this is reason of high power consumption.

What is the method for this problem?

Thanks in advance.

When you test this, do you use original Z-Stack examples without modification?

Yes I did try so.

When you see ZED power consumption sticks at 33 mA, does it keep sending beacon requests?

Yes,ZED send beacon request per 10 seconds.

Which Z-Stack version and example do you test? And, what HW EVB do you use?

ZStack version is 3.0.1.
And HW is self made.

If it is self made HW, how do you run original example without modification?
