1. Manual Guide
The Bluetooth Communication equipment User Manual was created to assist the user of the equipment.
Since content regarding specific usages are included in the introduction, the manual guide will assist in basic
methods in installing and connecting the equipment.
2. Introduction
The Bluetooth Communication equipment is a product that can be supported by a low-energy 2.4 GHz
interface on the PC. As the Bluetooth Communication equipment uses a Bluetooth 4.0 (BLE) system, it works
on very little energy. On the PCB surface, an antenna (reverse F type) is printed for Bluetooth communication.
When connecting the PC with the Bluetooth, using the supported serial interface speed (115200 Bps) is
recommended. The serial driver chip CP2104 is supported by the serial port.
* The USB port is service port.
3. Functions
On the PC, the serial port program is used to send and recieve packets. The settings of the serial port are
the following:
-Baud : 115200 bps
-Data bits : 8
-Stop bits : 1
-Parity: none
The data transmission's status can be monitored by the Bluetooth Communication equipment's LED's

4. Specific Features
1) Changing Modes
The Bluetooth Communication equipment's mode can be changed by pressing and holding the button on
the bottom right.
2) equipment Status
The equipment's currently pairing status with other devices can be monitored. When the light emitted turns
