XBEE 3 802.15.4 remote module configuration

Hallo,

I have recently bought a Xbee Zigbee mesh kit for my project.I need to use this in Point to Multipoint network (802.15.4 mode).

I have updated the firmware and followed this guide to configure the remote devices by changing the ID,NI,AP mode.

https://www.digi.com/resources/documentation/digidocs/90002273/Default.htm#tasks/t_configure_remote_devices.htm%3FTocPath%3DGet%2520started|_____4

But i could not succeed establishing a connection between two Xbees. I have also tired changing one Xbee as Coordinator and other as End device / both as End device. But i got no progress.

Any answers or suggestions will be very much appreciated.
