2. 协议说明
Protocol Description

蓝牙通讯协议采用帧进行通讯，每一帧采用了起始头、校验码、终止尾的方式进行数据校验。
The Bluetooth communication protocol uses frames for data exchange, with each frame incorporating a start header, checksum, and end tail for data validation.

2.1 UART 配置 / Uart Config

协议: baud, N, 8, 1（无校验，8 位数据，1 位停止）
Protocol: Baud, N, 8, 1 (No parity, 8 data bits, 1 stop bit)
波特率: 4800、9600、19200、38400、115200 自适应
Baud Rates: 4800, 9600, 19200, 38400, 115200 (Auto-adaptive)

Data follows little-endian alignment, meaning the least significant byte (low byte) comes first, followed by the most significant byte (high byte). 例: 数据0x1234，数据码为0x34 0x12；数据0x12345678，数据码为0x78 0x56 0x34 0x12。 Example: data 0x1234, the data code is 0x34 0x12; data 0x12345678, the data code is 0x78 0x56 0x34 0x12.
校验码 / FCS	1Byte	N Bytes	帧校验，所有指令码(CMD、SCMD)与数据码(DATA)字节按位异或后的值 The frame checksum is calculated by XOR-ing all the instruction bytes (CMD, SCMD) and data bytes (DATA).
终止码 / End Code	1Byte	0x03	表征通讯帧结束，固定的1 字节数据，为十六进制 The communication frame end is represented by a fixed 1-byte value in hexadecimal.

注: 数据采用【小端】对齐方式，即低字节在前、高字节在后。

3. 获取设备信息
Device Information Retrieval

3.1 初始化指令介绍 / Initialization Command Introduction

蓝牙模块在上电启动后会发送配置指令到设备，设备需按格式返回数据。
After power-on, the Bluetooth module will send a configuration command to the device, and the device must return data in the specified format.
设备型号是APP 识别的依据，因此设备必须按格式实现机型代码数据返回。否则运动秀APP 将无法识别当前蓝牙模块。
The device model is the basis for APP recognition, so the device must implement and return the model code data in the required format. Otherwise, the FitShow APP will not be able to recognize the current Bluetooth module.
设备返回数据根据设备类型有两种返回格式，如下所示。
The data returned by the device has two return formats depending on the device type, as shown below.

(Note: Ensure the baud rate matches. After sending, the module will not respond; proceed directly with the restart.)

4. 获取设备参数
Get Device Parameters

4.1 获取设备参数指令 / Get Device Parameters Command

该指令会在使用运动秀APP 时进行访问，对于非运动秀且支持FTMS 协议的设备，阻力范围默认为0-255 档，设备接收到的值也为0-255，可以根据这个范围去映射到自己的档位来调整阻力。
This command will be accessed when using the Sports Show APP. For devices that do not use Sports Show but support the FTMS protocol, the default resistance range is 0-255 levels. The values received by the device will also be in the range of 0-255, and you can map this range to your own levels to adjust the resistance.

获取设备参数指令 / Ble Send (0x41 - 0x02):

START	CMD	SCMD	FCS	END
0x02	0x41	0x02	0x43	0x03

设备返回 / Device Returns (0x41 - 0x02):

START	CMD	SCMD	DATA				FCS	END
0x02	0x41	0x02	阻力 (B) / Resistance (B)	坡度 (B) / Incline (B)	配置 (B) / Configuration (B)	预留 (B) / Reserved (B)	xx	0x03

字段 / Flag	说明 / Explanation
起始码 / Open Code	0x02
指令 / Command	0x41
子指令 / Sub-Command	0x02
阻力 / Resistance	设备可控制的最大阻力值，即阻力范围为0~最大阻力值，若设备不支持阻力控制，则返回0 The maximum controllable resistance value of the device, i.e., the resistance range is 0 to the maximum resistance value. 若设备不支持阻力控制，则返回0/ If the device does not support resistance control, it will return 0.
坡度 / Incline	设备可控制的最大坡度值，即坡度范围为0~最大坡度值，若设备不支持坡度控制，则返回0。当设备类型为登山机时，手动表的坡度恒定为1，仅有一种角度，角度根据机型码获取，电控表的坡度应当大于1，且其坡度与角度数据根据机型获取 The maximum controllable incline value of the device, i.e., the incline range is 0 to the maximum incline value. If the device does not support incline control, it will return 0. When the device type is a mountaineering machine, the slope of the manual meter is constant at 1, with only one Angle, which is obtained based on the model code. The slope of the electric control meter should be greater than 1, and its slope and Angle data are obtained based on the model.

4 - 7	高四位 (bit4-bit7) 用于负坡度范围设置，无负坡度则填 0 The upper four digits (bit4-bit7) are used to set the range of negative slope, and 0 is filled if there is no negative slope.

5. 获取设备状态及数据
Get Device Status and Data

设备当前状态是APP 运行的依据，也是APP 与设备互通的基础，因此在APP 连接蓝牙后就会以每秒3 次的周期不间断获取设备状态。
The current status of the device is the basis for the operation of the APP and is essential for communication between the APP and the device. Therefore, after the APP connects via Bluetooth, the device status will be continuously retrieved at a rate of 3 times per second.

速度 / Speed	单位: 0.01km/h 或 0.01mi/h，例如: 1000 代表10.00km/h 或10.00mi/h Unit: 0.01 km/h or 0.01 mi/h. For example, 1000 represents 10.00 km/h or 10.00 mi/h.
阻力 / Resistance	可以是档位: 比如1-16 或者1-32；可以是阻值: 0-255 Can be gear levels: e.g., 1-16 or 1-32; or resistance values: 0-255.

启动倒计时 / Startup Countdown	若设备不需要启动倒计时，状态直接从待机变化到运行 If the device does not require a startup countdown, the state will change directly from standby to running.

6. 获取运动数据 / Get Exercise Data

设备运行后通过此指令来获取当前运动量数据。
After the device starts running, this command is used to retrieve the current exercise data.

获取运动数据指令 / APP Send (0x43 - 0x01):

START	CMD	SCMD	FCS	END
0x02	0x43	0x01	0x42	0x03

START	CMD	SCMD	DATA				FCS	END
0x02	0x43	0x01	时间 / Time (W)	距离 / Distance (W)	热量 / Calories (W)	计数 / Count (W)	xx	0x03

数据项 / Data Item	说明 / Explanation
时间 / Time	代表运动从开始到当前的时间，以秒为单位 Represents the time elapsed from the start of the exercise to the current moment, in seconds.
距离 / Distance	在小于32000 时，最高位为0 单位为1，大于等于32000 时最高位置1 同时单位为10； For distances less than 32,000, the highest bit is 0, and the unit is 1. For distances equal to or greater than 32,000, the highest bit is set to 1, and the unit changes to 10. 例如: 当前距离为30000米，则返回30000 (0x7530)；若运动距离达到50000米时，返回37768 (0x9388)，值= 距离除以10 后将最高位置1。也可以一开始将最高位置1 来告诉APP 距离都是以为10米为单位。若为公制则传公制数据，英制则传英制数据。 For example: if the current distance is 30,000 meters, it returns 30,000 (0x7530); if the exercise distance reaches 50,000 meters, it returns 37,768 (0x9388), where the value = distance divided by 10 with the highest bit set to 1. Alternatively, the highest bit can be set to 1 from the beginning to indicate to the app that all distances use 10-meter units. Metric data should be sent for metric systems, and imperial data for imperial systems.
热量 / Calories	单位为千卡(0.1kcal) Unit: kilocalories (0.1 kcal).
计数 / Count	代表运动从开始到当前的感应器计数 Represents the sensor count from the start of the exercise to the current moment.
