I am building a project using Xbee ZigBee pro (S2C)
Raspberry Pi acts as a coordinator
TI-based microcontrollers act as ED or Router
For power saving, I am thinking of making all the microcontrollers as ED. So no Router in the network.
1. Realistically, the Router: ED =1:8. Now if I don't have any Router in my network, what is the ratio of Coordinator: ED?
2. How many Router per coordinator in case I decide to do that?
3. In my project, the coordinator needs to send commands to specific ED, receive data back from ED and needs to determine which ED is the data coming from and/or going to. I understand my cooordinator needs to run in API mode. Does the ED also needs to run in API mode? Or AT mode is enough for the ED in this scenario?
