In healthcare, more and more attention is being paid to developing personalized healthcare solutions. They are primarily based on patient-generated health data (PGHD). The main source of those are medical measuring devices and environmental sensors. In this diploma thesis, we learn about the basic concepts of IoT and the current trends in health care. Since most medical devices support BLE technology, the thesis describes some important features that are part of the BLE core specification. In order to provide simple data collection and management, I have developed the HealthySync system, which enables the integration of BLE devices into the OH2 smart home environment. It consists of the AndroidThings application and the OH2 plugin. The end-user has complete control of the system and the data, which can be shared with selected parties safely through the distributed IOTA network.
