How to have a bi-directional communication between two xbee s2

Hello. How to have a bidirectional communication between two xbee s2 modules? One is on the computer the other one is on the arduino? Like i want to send a string “Feed” or other string to the Xbee in the arduino from the computer and the Xbee from the arduino will send a notification to the xbee in the laptop?

Have you established a network yet with one being a coordinator an the other the default state being a router?

Have you tried running a simple range test yet between them?

Yes I configure already the router and coordinator and they have broadcast configuration too.

What you mean range test?

A range test is a function in Digi’s XCTU that verifies two way communications between radios.
