I am using XBee S2C Pro module
I have set 6 network with different PAN ID in star network.coordinator is mains powered and receives data send from End-devices. Each coordinator has 4 End devises. End Devices are battery powered and work in cyclic sleep mode. End devices send data to Coordinator after every one Minuit.
All 6 network are place side by side with no RF interference.
My setup work perfectly for 2 days. After that around 11:52PM transmitter of 5th coordinator start sending data to 6th coordinator.
Around 10:30 AM on next day, After giving Network reset command to 5th coordinator 3 End device rejoin again. after Power cycle to 5th coordinator, other transmitter also joint network back.
I have read operating PAN of End device connected with other network, it is same as 5th coordinator.(Require for proper communication)
How is this possible ?
How to prevent End device to connect to get connected with other PAN ID ?
Does Xbee chip save any back History ?
i.e if previously same chip was used as coordinator for these group of End devices.
I always give NR command at every power on of Coordinator.
(Coordinator is always power ON. NR is send only ones)
