Creation of Bluetooth data logger for recording and processing of measured data
Vaverka, Jan ; Myška, Vojtěch (referee) ; Dejdar, Petr (advisor)
The first part of the theses deals with dataloggers and their use in today's world. The second part is dedicated to microcontrollers which are used as a control unit for dataloggers. Individual peripheral devices MCU and their communication interfaces have been described. The next part deals with Bluetooth Low Energy which is used for data broadcasting to the user. Based on the acquired knowledge the microcontroller and sensors were selected. A datalogger was constructed and programmed from selected components, which will measure the properties of ferment during fruit fermentation. Finally, a mobile application was created to download data from the datalogger and then display the data in charts.

Detection of Security Incidents in Bluetooth Networks
Bárteček, Bronislav ; Hujňák, Ondřej (referee) ; Kořenek, Jan (advisor)
The goal of this bachelor thesis is to detect security incidents in Bluetooth Low Energy(BLE) networks. It was necessary to create a tool that would detect security issues in devices and monitor the activity of devices that communicate using BLE. Ubertooth was used in the solution to sniff BLE communication. Ubertooth is used to capture BLE packets, which are then decoded by the created program and analyzed. The created tool determines the device security rate from these data. At the same time, it monitors network activity and, if necessary, informs the user of unwanted device activities, such as connecting foreign devices to user devices.

Internet of Things
Piškula, David ; Nosko, Svetozár (referee) ; Musil, Petr (advisor)
This thesis focuses on the Internet of Things and some of the most important problems it faces today. Among these are the overdependence on the Cloud and lack of autonomy, poor security and privacy, complicated initialization and power consumption. The work aims to implement a complex IoT solution that solves the discussed problems. The project is part of a collaboration with NXP Semicondutors and will be used to showcase the company's technologies.

Mobile application using Google beacon technology
Krajanec, Štefan ; Hajný, Jan (referee) ; Dzurenda, Petr (advisor)
This Bachelor thesis focuses on utilizing beacon technology in Android applications. Beacon technology allows for determining an approximate distance of the user from the beacon.. In order to verify the reference numbers given by the manufacturer we conducted an observation to measure the power of the received signal in reference to distance. 3 brands of beacons were tested, Kontakt.io, PROXioT and IBKS. The observasion has been iterated in an open field setting. Findings from this observation was implemented into an application designed for shopping mall marketing. The application, after getting closer to the beacon distinguishes between different behaviour types; behaviour as an instant notification, as a position log into a database, as a time stamp log (time spent near the beacon) into a database and as a conditional response. The aim was to resolve the problematics of communication with the beacon as universally as possible so the impletation into other projects would be as simple as possible. The aforementioned app is the output of this thesis.

Bluetooth Low Energy Voting Device
Vybíral, Tomáš ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
This bachelor's thesis deals with the design and implementation of embedded voting device and application for voting. The proposed voting device uses Bluetooth Low-Energy protocol which helps to achieve low energy consumption. The result of this thesis is a fully functional prototype. UI application was created using the Qt framework and is responsible for handling wireless connections, processing of individual voices and displaying the voting results.
