Many smart health devices implement Bluetooth Low Energy (BLE) due to the benefits of low power usage, ease of implementation and ease of transfer of data to their mobile devices. Theses devices store records that may contain useful information in a criminal investigation, investigators could acquire from a range of smart health care devices to debate the users last movements. However, it is difficult to obtain this data, as there are currently no tools or methods. In this work we present a novel acquisition method, using BLE to collect records stored on smart Blood Pressure Monitors (BPM). We did further experiments to test the robustness and reliability of this method on two other BPMs. We identified a realistic use case on how this method can be useful in practice.
