Abstract: The number of Internet of Things devices has been increasing rapidly in the recent few years, which opens possibilities for many new use cases. One of those is tracking assets, specifically for the conservation of endangered animals. This is the main goal of the OpenCollar tracking device. Its features and communication technologies are described in this master’s thesis. The device supports a variety of configuration options enabling users to tweak it for their specific usage. The main focus of the thesis was to design, implement, and test a cross-platform mobile application that would simplify the configuration process of such a device. All aspects of the application are described with a focus on the communication protocol. In the end, we present the results and conclude that the implemented application greatly simplifies the management of OpenCollar devices.Keywords: Internet of Things, mobile application, Bluetooth low energy, Long RangePublished in DKUM: 28.01.2022; Views: 485; Downloads: 40 Full text (3,08 MB)
