hi i'm using xbee3 as a coordinator.
and i connected xbee to some iot sensors.
if these are connected, i can receive message through uart.
but i can not check disconnection.
1. so how can i check if these sensors are disconnected?
one way i think is sending data in real time.
but this way is inefficient.
when checking rf packets with a packet sniffer. I can see some broadcast packets to check link status.
2. can i receive these packets with uart?
