No data transfer back to Router only one direction to Coordinator

I have two Xbee Pro X3B’s setup (Router, Coordinator)that I can transfer data both direction in AT mode but when in API mode only R to C? What am I missing?

Are you putting your Coordinator in API mode? API mode changes the way the UART processes data, any input must be packetized into API frames with the proper formatting.

Yes, Router and Coordinator both are in API mode that didn’t work.

I got it working by changing CE on the Coordinator to “indirect Msg Poller” instead of other Coordinator settings. I don’t understand why at this point but open to information on this selection.

My main objective is to have the Xbee’s to communicate in a bi-directional manner.

Why??
