Data logger
Dráb, Dominik ; Pazdera, Ivo (referee) ; Ctibor, Jiří (advisor)
This master's thesis deals with design of universal data logging device. The work proposes the design of device architecture and describes individual systems and components, that are necessary for data logging. Logger is designed as a mobile device, with ARM microcontroller at its core. Thesis specifies requirements for device in terms of performance and versatility. The device uses modular construction, as it comprises multiple PCBs. The thesis describes their design and also design of the mechanical construction of data logger. Designed device has been realized and assembled. Software design for microcontroller is also part of the thesis. In the last part, measurements to determine achieved parameters of the device are conducted.

Wireless Sensory Network Using LoRa Technology
Mikulášek, Michal ; Pokorný, Jiří (referee) ; Škorpil, Vladislav (advisor)
The bachelor thesis focuses in the first half on the Internet of Things and the available wireless technologies for the Internet of Things. Each technology is characterized by its features, pros and cons, as well as the possibilities of using it in the Internet of Things. In the second half of the thesis, a practical design and construction of a LoRa network, consisting of a sensory and a central unit, is carried out. The parts of the solution are designed wiring schemes, printed circuit boards and detailed photo documentation. Additionaly the software solutions for both types of units are described, with detailed descriptions of the proposed features. The maximum possible range is tested and documented for the entire solution. Subsequently, a detailed measurement of the power consumption of the sensor unit is carried out and an extensive estimation of its battery life for a selected battery.

Bluetooth Vibrating Ringer
Dočekal, David ; Dušek, Martin (referee) ; Povalač, Aleš (advisor)
This thesis is focused on the implementation of Bluetooth communication between a mobile phone and an external device. The first chapter focuses on Bluetooth technology in general. It describes the interface, device classes according to RF power, Bluetooth versions, security and pairing options. The second chapter of the Bachelor’s thesis deals with the Bluetooth module called HC-05. It describes the basic features and practical, module usage. It also shows the concept of the Bluetooth unit and describes the adjusting of certain parameters of the HC-05 module using the AT commands. The third chapter summarizes the deign and implementation of the device. Software and firmware development is overviewed in the fourth chapter. The testing and measurement results of the complete device are presented in the last part of this thesis.

Chat and Shared Drawing Board for Mobile Phones with Bluetooth
Pitner, Ivo ; Rogalewicz, Adam (referee) ; Novosad, Petr (advisor)
This work deals with analysis, design and implementation of application for mobile devices which allows two users to communicate. As an examle would be a situation where people wants to comunicate but it is not alowed to disturb the surrounding with conversation. The comunication is with text messages or graphic primitives. The program is written in Java 2 Micro Edition and a Bluetooth interface is used for a connection between devices.

Design of Standby Handsfree Headset
Dvořák, Jan ; Sládek, Josef (referee) ; Křenek, Ladislav (advisor)
The task for this bachelor work is to design a device, which can connect a user with the emergency call center in case it is needed. It has to be an accessory for the interior of the new Škoda Kodiaq vehicle and it can not affect its design or the production. The solution is a Bluetooth handsfree headset, connected to the Škoda eCall. It is always in the car ready to be used. Not a single car manufacturer offers such a device. Therefore it is so unique.
