It has amazed me what the Uno is capable of doing. Paired with a Dragino LoRa Transceiver, I have been able to send static images via LoRa P2P. Unfortunately, Dragino no longer manufactures that transceiver. Am unable to get their replacement to carry out a simple AT query and deliver the complete return message. The existing project's software and documentation can be found at GitHub - SoothingMist/Scalable-Point-to-Point-LoRa-Sensor-Network: Builds a peer-to-peer network of LoRa transceivers for remote sensing. Uses flood-messaging to eliminate need for LoRaWAN and third-party services..
