Bluetooth Low Energy (BLE) has emerged as one of the main wireless technologies used in low-power electronics, such as wearables, beacons, and devices for the Internet of Things (IoT). BLE's energy efficiency characteristics and ease of use interface are essential features for the design of ultralow-power devices. The integration of BLE with various sensors is certainly the main aspect for the development of efficient solutions, and monitoring the power consumption of the device in all the cycles of operation is important for decisions such as advertising interval, sensor routine and data transmission. Recent work of BLE power analysis focuses on the theoretical aspects of the advertising and scanning cycles, with most results being presented in the forms of mathematical models and computer software simulations. Such models and simulations are particularly important for the understanding of the technology. However, many times they leave real applications out of scope. This thesis covers the implementation of a multi-sensor Bluetooth Low Energy system, and the study of the communication protocol regarding its power consumption and RF performance. The implementation consists of a battery powered custom Printed Circuit Board (PCB) featuring the Texas Instruments CC1352P7 as the main SoC and three different sensors capable of measuring 6 different parameters. The sensors are the BME688 from Bosch, and the ADXL343 and AD5941 from Analog Devices. The characterization process was performed using Keysight EXR Oscilloscope and 208A Spectrum Analyzer. The proposed design has dimensions of 28 mm × 35 mm. The current consumption of the implemented design with one sensor in operation is 4.1mA and 7.1mA, and 6.9 mA combined.

The need for small versatile sensors is ever-growing. The demand to create sensors that are more versatile and resilient while still improving in size and speed is only growing. As this technology improves, we find more innovative applications. These new applications are bringing this technology out of strictly the academic and industrial realm and bringing it into everyday life. People are now able to run important medical tests on the fly without anything more than a watch or ring. Athletes are able to extract important statistics data from practice to improve their craft and increase safety. This research aims to create a universal platform to interface with a group of different sensors that is easy to use, versatile and expandable. To make the platform easy to adapt, it should be developed to work with existing infrastructure that people are already familiar with and have easy access to. Bluetooth Low Energy is a technology that is present on nearly all mobile devices, which makes it a great mode of communication. A sensor platform system is developed from the hardware level all the way to the application layer, reading data on a mobile device. This system also avoids the problems of other implementations with limited adaptabilities.

Several of the actual devices, such as mobile phones, use Bluetooth Low Energy, a wireless technology that is able to establish a connection between devices producing a low energy consumption. Therefore, in this project this technology has been applied in low resources and low consumption nodes. The objective is to analyze these nodes, know their characteristics and to be able to develop different applications in different sensor networks, for instance biological measures in human beings or environmental measures. To achieve this objective a first design was made, where the Bluetooth Low Energy was studied and the node used, the device CC1352R. Subsequently, in order to implement the pertinent functions, the code for each node was elaborated. The final scene that has been developed consists on two CC1352R devices that utilize this technology to be able to establish a connection, receive data, transfer it between nodes and store it in the central node. In this project a study of the current state of the Bluetooth Low Energy technology was elaborated, in addition to the description of the development of the functions used in the CC1352R devices. Furthermore, an experimental study was made about the lecture of data and limitations of the nodes. The study and development of this work serve as collateral to accomplish new projects, as in creating different applications related to the Internet of Things an the ability to create different kinds of sensor networks.

The First Complete Guide to Bluetooth Low Energy: How It Works, What It Can Do, and How to Apply It A radical departure from conventional Bluetooth technology, Bluetooth low energy (BLE) enables breakthrough wireless applications in industries ranging from healthcare to transportation. Running on a coin-sized battery, BLE can operate reliably for years, connecting and extending everything from personal area network devices to next-generation sensors. Now, one of the standard’s leading developers has written the first comprehensive, accessible introduction to BLE for every system developer, designer, and engineer. Robin Heydon, a member of the Bluetooth SIG Hall of Fame, has brought together essential information previously scattered through multiple standards documents, sharing the context and expert insights needed to implement high-performance working systems. He first reviews BLE’s design goals, explaining how they drove key architectural decisions, and introduces BLE’s innovative usage models. Next, he thoroughly covers how the two main parts of BLE, the controller and host, work together, and then addresses key issues from security and profiles through testing and qualification. This knowledge has enabled the creation of Bluetooth Smart and Bluetooth Smart Ready devices. This guide is an indispensable companion to the official BLE standards documents and is for every technical professional and decision-maker considering BLE, planning BLE products, or transforming plans into working systems.
