We have a network with one coordinator (XBP24 ver 1141) and 24 router/ enddevices (1XBP24 ver 1341). The network was gradually expanded (first 10 router/ enddevices, another 6 and finally last 8). Now we face some problems which were not noticed when we had lesser number of modules.
When all the router/ enddevices are powered up simultaneously (all are connected to mains power with step down to 3 v), we find that some router/ enddevices donot join the network. We had a rare case where none of the router/ enddevices joined. The association LED is solid (not blinking) in the router/ enddevices which didn’t join.
We also noticed a scenario when a router/ enddevices which joined the network going out of coomuncation. It doesn’t tranmit/receive data and also link test fails but association LED is blinking correctly. It joins the network on its own again or after a power reset.
We don’t know which modules work as routers and which as enddevices. Dicovery using XCTU remote configuration shows all as routers.
This issue is affecting the reliability of the set up and now we are worried about suitability of XBee in critical applications.
Any help will be highly appreciated.
