LFR: Um Modelo De FUOTA Via LoRa

Every year more IoT devices are installed worldwide, predictions for 2025 are that we will have about 75 billion devices worldwide, so more and more firmware update becomes necessary to maintain the useful life of these applications.In this article we propose a FUOTA via LoRa.The model is composed of four steps: configuration, update, activation of future seeds and activation of common devices.After that, a proof-of-concept was implemented.The laboratory and field tests were then detailed.It was concluded with the results that the LFR is able to obtain a transfer time lower than those reported in the literature.
