The QN9080DK is a development board from NXP specifically for the wireless access market, which has an integrated QN9080 Bluetooth system-on-a-chip (SOC) with an Arm CortexM4F core and a dedicated fusion sensor coprocessor. In this paper, with the help of MCUXpresso integrated development environment (IDE), SDK, CrotexM4F core, Bluetooth 5.0, serial communication, Arduino software and hardware and so on, a Bluetooth fingerprint lock controller is designed and fabricated. The lock controller has the functions of user Bluetooth password access and unlocking, fingerprint entry, fingerprint unlocking and fingerprint permission deletion, etc. After the joint debugging of system software and hardware, the designed Bluetooth Low Energy (BLE) 5.0 fingerprint smart electronic lock controller meets the expected requirements.
