I'm having lots of trouble creating a point to point network with my Diji XTP9B-PKC-UA modules.

I’m trying to use two XTP9B-PKC-UA modules to use as a link for my pixhawk UAV flight controller but I cant even get the two devices to commmunicate. I’m not sure what I’m over looking but they dont seem to be communicating at all. If someone could please provide an example DT and MY configuration between my ground station and UAV it would be greatly appreciated.
