I would like to create a point-to-point connection between a LoRa temperature sensor and a M5 Stack (ESP32) with LoRa module. However, I am a beginner with LoRa, so I have a few questions:
Are all packets send with LoRa (not LoRaWAN) encrypted? Or does it depend on the producer of the LoRa sensor? Can the content of the packet received by the M5 Stack be viewed? (If I understand correctly, with the LoRaWAN the content can only be viewed after it is on the server). Can I send measured temperatures from multiple LoRa sensors to one M5 Stack? If yes, how could I distinguish from which sensor the packet has been sent?
Any help would be appreciated!
