Bluetooth is a wireless technology standard whose basic task is the wireless exchange of data between devices. Such exchange is possible at short distances using UHF radio waves within the ISM band: 2.403 GHz – 2.480 GHz. Recently, with the advancement of technology, the healthcare system is increasingly using BLE to transfer data between devices. The main reasons are: low energy consumption, security and good connectivity. Therefore, the main goal of this work is to collect data about the patient's vital parameters from the BLE bracelet E66 Fitness Tracker, and save them in a safe and precise database. At the beginning of the practical part of the work, the range performance of the BLE bracelet was tested despite the obstacles: wall constructions, metal objects, reflections, signal interference. The measurement obtained a maximum range of 18.03 m with the presence of obstacles, which makes it possible to cover three rooms of 20 m2. The measured range performance was followed by the collection of data from the BLE bracelet E66 Fitness Tracker into the IoT ecosystem. InfluxDB Cloud is a database that provides time-dependent saving precision as well as tokenbased security. Based on the API, collected data about oxygen value, integer and float temperature values and heart rate are delivered to InfluxDB Cloud, while the saved data is displayed using the Influx interface. The Influx interface has the ability to visualize data in the form of tables and graphs depending on the selected option.
