I have configured a network of 1 coordinator to 16 end devices in which we have done continuous 3 days network communication testing. In these 3 days data transfer between the coordinator and end device is successful with zero loss and no range issues. The communication was successful even after the coordinator is power off and then on after sometime, still the end devices did not loose the network. After 3 days I had turned the coordinator OFF for some 10mins duration n end devices were on. When I turned on the coordinator back, the end device did not retrieved and loss of communication was found. I left the system as it to observe whether they will get retrieved on their own, and all end devices were back into network one by one after a duration of 6-7hrs.
Since then I started testing in this way of turning off the coordinator and on to check whether same problem is observed again. Then I observed that by performing this test the end devices are loosing network in between and are retrieved again on their own. I am facing same problem on site where there are 6 coordinators installed against each there are 2 end devices. they tend to loose the network and go into communication failure for any unpredictable time duration from 1min to 5-6 hours. Kindly suggest what can lead to such issues and how I can work out to solve them.
The module I am using is S2C XBP24CZ7UIT-004-revD
Thank you in advance
