Desenvolvimento de um software android e um firmware para esp32 visando geolocalização em curtas distâncias para ambiente outdoor utilizando o protocolo bluetooth low energy. Orientador: Victor Araújo Ferraz. 2023. 57 f. Trabalho de Conclusão de Curso (Graduação em Engenharia Elétrica) - Departamento de Engenharia Elétrica, Universidade Federal do Rio Grande do Norte, Natal, 2023.https://repositorio.ufrn.br/handle/123456789/53726The present work is a Proof of Concept (PoC) aiming to develop an architecture capable of providing continuous monitoring of a remote device's geolocation by a user, alerting them if the device exceeds a certain range. For this purpose, an Android software and firmware embedded in an ESP32 microcontroller were developed, combined with the A9G GSM/GPRS/GPS module and Bluetooth Low Energy communication protocols, to provide this functionality. The application seeks to pave the way for the development of a future wearable that can be used on animals, people, objects, or devices, with the purpose of preventing potential material or immaterial losses. Throughout this work, the theory used will be presented, explaining how the software, firmware, and hardware were developed for validation, as well as the results obtained in the range tests. Finally, the advantages and areas for improvement of this work will be discussed, with the aim of generating future studies for this type of application.Attribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/Bluetooth low energyAndroidESP32GeolocalizaçãoGeolocationbachelorThesis
