Bluetooth proximity switch_XY-MBF12 base plate

I. Shenzhen XinYi Information Technology's XY-MBF12 Bluetooth proximity switch baseboard features an exposed power supply, serial port, and special pins. These pins
  allow for configuration via a serial port assistant, enabling seamless connection. For example, when a person approaches a door, their mobile phone automatically connects to the module via Bluetooth, triggering a special pin to open the door without contact. The initial Bluetooth connection password can be configured via the serial port assistant, and connections from unknown mobile devices can be prevented, significantly enhancing security.
II. Module Introduction:  
  The XY-MBF12A module is based on the FR8012HAQ chip from Freqchip Technology Co., Ltd. The FR8012HAQ is a low-power Bluetooth chip designed for easy and rapid development in a System-on-Chip (SoC). Supporting Freqchip's Bluetooth smart firmware and protocol stack, it is fully compatible with the Bluetooth V5.1 (LE mode) protocol. Users can also develop various applications based on the chip's built-in ARM Cortex-M3 embedded 32-bit high-performance microcontroller. It is mainly used in smart wearable devices, portable medical devices, sports and fitness equipment, smart homes, consumer electronics, and industrial control, meeting the requirements of low power consumption, low latency, and short-range wireless data communication. The XY-MBF12A transparent transmission module allows developers to develop smart products that support Bluetooth Low Energy communication without needing to understand the Bluetooth Low Energy protocol, using a serial communication-like method.
 
 III. When a mobile phone connects to this module via Bluetooth, a special pin on the module will activate; the activation timing can be configured via the serial port command sending instructions in the module's datasheet.
