# Beurer BM59 Unlocked: reconstructing direct BLE measurement transfer

> Beurer BM59 Unlocked documents the BLE exchange used by a BM59 blood pressure monitor to transfer measurements. From Android HCI captures, the author maps Nordic UART handles, the time write and measurement indications, and provides a Python client using Linux L2CAP/ATT sockets.
