Hello Seah, That's certainly not a trivial task. If you want the devices to behave as two addressable network interfaces with a link between them, I believe you'd have to modify a whole lot of things (the UHD driver -or directly bypass it-, the way TCP/IP/Ethernet framing is done inside the FPGA, and then implement some wireless protocol to carry your IP messages over the air -which would include defining operation frequencies, symbol rates and shape, coding schemes, synchronization, error control, etc.-).
I'd suggest you use the devices as are intended for a start (i.e., as software-defined radios), and try transmitting and receiving simple messages using the whole API + GNU Radio. This would not turn your devices into pingable devices, of course, but you'll be able to experiment vastly on an application-layer level. Still, we are not sure what your main goals for using your devices are. Could you tell us a little more about their intended use? Regards, Leo.
