Hello, everyone.

i’m in trouble.

I use Xbee zb series2 with my project.
Topology was very simple. Just one coordinator, one End-device.

Transmit mode was API mode.

and I tried setting Xbee cyclic sleep (SO:6)

It’s wake up every minutes. (SN: 3, SP:7D0)

also I give same sleep settings End device and coordinator (SN and SP).

and power supply is made stable over USB.

I used latest firmware version.

In the beginning it’s worked nice.

but after about 2 to 10 hours?

Xbee not send any data.

It looks like freezing.

I want to check Xbee status.

so I used logic analyzer.

but electronically no problem.

I think this problem is S/W.

Please help me!!
