Asking for the used library

[CSXizhang]

Hello, In your repository, you use gr-lora as the receiver, gr-lora-sdr as the transmitter and I see gr-lora-sdr has both transmitter and receiver. Could you let me know why you used it like this? What are the underlying reasons? I'm doing a project about making message transmission using plutoSDR based on LoRa and I'm trying transmit messages through SDRs on gnuRadio, but encountering some problems with adding LoRa to my flow graph.
If you could answer my questions above, I would appreciate it.
