Hello, Nice to meet you. I have ever developed similar project. I have raspberry pi and Lora module now , so I can start your project just now. There are two types in lora communication , one is raw lora and another is LoraWan. Do you need relay function in this system? If you are going to use relay function, you should use raw lora, because LoraWan has no relay function. I hope to discuss more with you by chatting. Best regards.

I'm an experienced developer with a keen interest in the Raspberry Pi. I've worked on many Pi related projects using various input/output boards. I'm currently using the ublox M8P RTK GPS (base and mobile) on a robotic rover project - driving via specific waypoints. I've not used LORA modules before but should soon be able to learn how to use them. Your project sounds very exciting and I would be very interested in working with you.
