Hi, I can help design the Bluetooth-enabled PCB for your fingerprint lock and integrate it with the fingerprint module and mobile control system. I have experience with ESP32/STM32/nRF embedded systems, Bluetooth communication, PCB design, sensor/module integration, and firmware development. I can handle the PCB, Bluetooth communication, lock/unlock control, administrator/client management, and the interface required for the mobile application. Security will also be considered for remote commands so unauthorized users cannot control the lock. Please share the fingerprint module model, lock/actuator type, battery voltage, and whether you already have a mobile app or need the communication interface defined as well. I can then suggest the best MCU/Bluetooth architecture and PCB approach.
