Connect offboard computer on SITL

Hi everybody,

I would like to connect a B-L072Z-LRWAN1 (it is a discovery kit of st) directly to the simulator. This kit has only to receive a telemetry message from the simulator. I still haven’t pixhawk, but I would like to establish communication from the LORA device to Simulator with PX4 by means Serial Port emulated on USB.
It is possible to make it? Which simulator have I to use?
Thanks for the answer.
