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!!
