Xbee 900 Pro Initialise help!

I can communicate with both my Xbee’s via usb breakout but when I try to communicate between the two eg send data i have no luck, when I look at the network map in XCTU i can see the other Xbee (i have the co-ord connected via USB) It just says unable to initialise the Xbee.

Full code + pix of hardware setup ?

A good intermediate troubleshooting step might be to place both xbee’s on digi prototype (USB) boards and retest.

It would also be helpful to see the configuration of each of them that you’re using.
