Hi! I have XBee3 as coordinator of my network. I have recently upgraded to 100A (but noticed the issue in 1009). The network consists of various xiaomi sensors, a xiaomi power relay (works as mains powered zigbee router), and other XBees, including XBee3 and S2C.
The issue is that some of my devices start leaving network after a while (several hours to several days).
It seems that the most affected devices are the endpoints that communicate directly to the coordinator. Routers are either not affected or affected much less. Endpoints that communicate via routers are also either affected less or not affected at all.
I'm sure some of the older firmwares work correctly. However when I've tried to downgrade the firmware to test I found it was impossible for some reason.
May be the issue is related to the fact that endpoints (sensors) are not sending any data very often. I have an illumination sensor that sends updates very often, and it works fine despite being an endpoint. At the same time a cube sensor, which only communicates when I interact with the device, is probably the first to disconnect. I will also try switch off one of the xbee3 routers for the experiment to check if it would lose the network or not.
US=0, C8=0x10, EE=1, EO=2, RK=0, DO=0x40, VR=100A, VH=181, HV=4247, R?=0.
Please advice. This must be a known issue!
