I have one coordinator, router and few xioami zigbee sensor devices.The Aqara sensor's parent is router and data is received at the coordinator via this router. Initially 64 bit source address in the data received from the sensor was
**00 15 8D 00 02 B8 4D AA**

But after turning power Off and On of coordinator, the 64 bit source address in the data received changed to

**FF FF FF FF FF FF FF FF**

**Zigbee Sensor Data before power off was as follows**.

Explicit RX Indicator (API 1)

7E 00 19 91 00 15 8D 00 02 B8 4D AA BF 50 01 01 00 06 01 04 00 18 10 0A 00 00 10 00 BD

**After Power Off and On at coordinator**

Why 64 bit source address changed?
