The project itself has two parts, one is the app that is this one and the other part is the hardware that is responsible for passing on the app information to Lora and saw Versa. To run the application just go to ./file_transfer_lora/bin/debug or https://github.com/elceza/lora_file_transfer/tree/main/file_transfer_lora/bin/debug and execute the .exe file. have a signature regarding my computer where I developed the app. In this case, just ignore the message and run the app, but if you don't feel comfortable, I recommend reading the code and even performing an antivirus scan.
