The maximum supply voltage should not be exceeded. 2）模块通过串口与外部设备进行通信。 Module communicates with external through serial ports 串口配置：Serial port specifications:  波特率Baud rate 115200  数据位Data bits：8bits  停止位Stop bit：1  奇偶校验Parity check：No 3）控制端MCU与模块通信如下图 Communication between MCU control end and BLE module 4 5. 接口说明 Interface 在命令模式下，MCU 发出命令，模块收到命令后，就会立即解析该命令，并给出相应 的响应帧，从发出命令到收到相应需要一定的时间。命令的响应时间不会超过 20ms，典型 值在 8-10ms 之间，在模块有其他更高级的任务处理的时候，响应时间会变长一些，但不 会超过 20ms。 MCU 要将数据发送出去时，需要遵循一定的时序，低功耗蓝牙的通信速率是有限的， 为了防止拥塞造成的大量丢包，MCU 向模块写入 数据的速率不能太快。每包数据需要间隔20ms。 In command mode, MCU will send commands, and after the module received a command, the module will immediately parse the command and give the corresponding response frame. It takes a certain time from issuing the command to receiving the corresponding frame. The response time of the command will not exceed 20ms, typical values are between 8-10ms, and the response time will be longer when the module has other more advanced tasks to process, but will not exceed 20ms. When MCU needs to send data out, it needs to follow a certain time sequence. The communication rate of low power consumption Bluetooth is limited. In order to prevent packet loss caused by congestion, the MCU cannot write data to the module at an extremely fast rate. The interval for each data packet should be at least 20ms. 1）串口数据帧结构 Serial data frame structure 透传模块的命令有一定的格式，包含“字头”、“命令 ID”、“命令信息长度”、“命令信息” 五个区域。Commands from transparent transmission module have certain format. The 5 command should contain five parts, which are prefix (2 parts), command ID, command length and command data. 2） 串口命令Serial port command 发送 Send command 字头Prefix I 01 1 byte 字头Prefix II FC 1 byte 命令 ID Command ID CMD 1 byte 信息长度 Command length LEN 1 byte 信息内容 Command data DATA N byte (N<255) 应答 Answer command 字头Prefix I 04 1 byte 字头Prefix II FC 1 byte 命令 ID Command ID CMD 1 byte 信息长度 Command length LEN 1 byte 信息内容 Command data DATA N byte (N<255) 3）串口命令Serial port command 0x07 查询MAC地址 Querying MAC Addresses 0x12 设置广播 Set broadcast 0x25 连接到指定设备 Connect to the specified device 0x2A 已连接Connected 0x41 发送数据 Send data 6 0x42 收到数据 Receive data 0x43 断开连接 Disconnect 0x48 睡眠 Sleep 4) 常用指令说明 Frequently used commands 命令字 命令描述 示例 07 MAC 地址查询 格式：01 FC 07 00 返回：命令正确 04 FC 07 06 xx...(共 6 个字节，低字节 序) 命令错误 04 FC 02 00 12 广播数据设置 格式：01 FC 12 xx（广播数据长度）xx...（广播数据） 广播数据长度取值范围是 1-29，必须与后面广播数据字节 数相符 上电默认：空 返回：命令正确 04 FC 01 00 命令错误 04 FC 02 00 41 发送数据（透传） 格式：01 FC 41 xx (数据长度) xx...（用户数据） 数据长度取值范围是 1-80，用户数据字节数必须和数据长 度相符 返回：能正常发送 04 FC 01 00 不能正常发送 04 FC 02 00 42 接收数据（透传） MCU 向模块发送该命令无效，当模块收到数据，并且模块 处于命令模式时，模块主动向 MCU 发送该命令的响应， 响应的格式如下： 04 FC 42 xx(数据长度) xx...（用户数据） 数据长度的范围是 1-20，后面紧跟用户数据 7 Command Description Example 07 Querying MAC Addresses Format: 01 FC 07 00 Return: Correct command should be 04 FC 07 06 xx...

The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with FCC requirements under conditions of excessive data rates or over-modulation. 15.212(a)(1)(ii) ☒ - YES ☐ - NO(*) Details: Yes , All inputs to the modules are buffered through logic or microprocessor inputs. 3. The modular transmitter must have its own power supply regulation on the module. This is intended to ensure that the module will comply with FCC requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. 15.212(a)(1)(iii) ☒ - YES ☐ - NO(*) Details: YES – The module contains its own power supply regulation. Please refer to schematic filed with this application> 4. The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b), 15.204(c), 15.212(a), and 2.929(b). The antenna must either be permanently attached or employ a ‘‘unique’’ antenna coupler (at all connections between the module and the antenna, including the cable). The ‘‘professional installation’’ provision of § 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph 15.212(b). 15.212(a)(1)(iv) ☒ - YES ☐ - NO(*) Details: YES – The module use PCB Antenna 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)). 15.212(a)(1)(v) ☒ - YES ☐ - NO(*) Details: YES – The module was tested stand-alone as shown in test setup photographs filed with this application> THIS MUST BE SIGNED BY THE APPLICANT/AGENT AND SHOULD BE PLACED ON APPROPRIATE LETTERHEAD Modular Approval Requirement Requirement Met 6. The modular transmitter must be labeled with its own FCC ID number, or use an electron display (see KDB Publication 784748).

FCC 47CFR §2.1091 REQUIREMENT 2.1 TEST STANDARDS Follow the maximum permissible exposure (MPE) limits specified in 447498 D04 Interim General Radio Frequency Exposure Guidelines v01. The gain of the antenna used in the product was extracted from the supplied antenna data sheet and the maximum total power input to the antenna was also measured. Calculate the distance from the product to the MPE limit by the formula. 2.2 LIMIT For single RF sources (i.e., any single fixed RF source, mobile device, or portable device, as defined in paragraph (b)(2) of this section): A single RF source is exempt if: (A) The available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption may not be used in conjunction with other exemption criteria other than those in paragraph (b)(3)(ii)(A) of Part 1.1307. Medical implant devices may only use this exemption and that in paragraph (b)(3)(ii)(A); (B) Or the available maximum time-averaged power or effective radiated power (ERP), whichever is greater, is less than or equal to the threshold Pth (mW) described in the following formula. This method shall only be used at separation distances (cm) from 0.5 centimeters to 40 centimeters and at frequencies from 0.3 GHz to 6 GHz (inclusive). Pth is given by: Page 7 of 9 Report No.: STS2408140H01 (C) Or using below table and the minimum separation distance (R in meters) from the body of a nearby person for the frequency (f in MHz) at which the source operates, the ERP (watts) is no more than the calculated value prescribed for that frequency. For the exemption in Table 1 to apply, R must be at least λ/2π, where λ is the free-space operating wavelength in meters. If the ERP of a single RF source is not easily obtained, then the available maximum time-averaged power may be used in lieu of ERP if the physical dimensions of the radiating structure(s) do not exceed the electrical length of λ/4 or if the antenna gain is less than that of a half-wave dipole (1.64 linear value).
