Descripció del contingut i pla d'activitats:
Internet of Things (IoT) is increasingly every day. IoT means that each device is connected to the network, Internet, to send and to receive data. It is estimated that by 2020 there could be around 5000 million objects.

Many of these devices are nodes with few resources: little memory, low computing power, low energy and they are autonomous. Wireless sensor networks (WSN) are composed of these types of devices. They are networks of sensors nodes that measure parameters of their environment, store these measures and transmit to a control centre. Such nodes must be autonomous, no maintenance by persons, so they must obtain their energy from their environment. There are many nodes that fulfil these features. Several of them are the Texas Instruments nodes.

The objective is to develop a network with those nodes and evaluate their advantages and disadvantages. This network has two strong points: Bluetooth Low Energy, this protocol is used for the Internet of Things (IoT), and the use of low resource platform.
 
Overview (resum en anglès):
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.
