We recently migrated from Atmega128RFA1 (BitCloud 1.14) to SAMR21 using BitCloud3.2. Our earlier network had one coordinator, 26 routers and 24 end devices, with end devices being allowed to connect only to routers. Our current SAMR21 network has one coordinator, 20 routers and 12 end devices, again end devices allowed to connect only to routers. The only change we made was to update Coordinator and router network parameter to support bigger network.
With the Atmega128RFA1 running BitCloud 1.14, our connectivity was excellent and even in case of issues, devices would just not connect. However, with SAMR21 and BitCloud 3.2, we face lot of issues like network congestion, packet loss, and even worse, end devices connect and leave the network as soon as they join. We would like to understand if this is a problem that only we face or if others have also seen such behavior. And, is there something specific that we need to do in 3.2 to avoid such a situation?
To complete the picture, all our Atmega128RFA1 boards were same whereas the SAMR21 HW boards are of different form factor to meet product aesthetics. And we use RFMD IC on coordinator for antenna diversity.
It would be great if we can get some advice on this tricky situation we find ourselves in.
Thanks & Best Regards,
