蓝牙商标使用规范

正确：蓝牙® 无线技术
拼写蓝牙书写为英文 Bluetooth 时是商标，因此它的拼写不能改变。它应该始终以英语，它的繁体中文翻译 “藍牙” 或它的简体中文翻译 “蓝牙” 使用，而不能被译作其它语言。
错误：Blåtand ® trådlösa produkter... 正确：Bluetooth® trådlösa produkter... 正确：藍牙 enabled product 正确：蓝牙 enabled product

如需咨询在其他场合中商标的使用，请发邮件至 brand.manager@ . 联系商标经理。被授权方将商标用于产品或相关产品上的权利取决于上述产品的资格证明，且包括在与 Bluetooth SIG 签订的蓝牙商标许可协议之中。
格式在纯文本中使用文字商标时，字幕 “B” 必须用大写（例如 “Bluetooth” ），且字符商标应突出显示，在文本中可通过下划线突出，或采用大写字母、斜体或加粗显示。
同样，当蓝牙文字商标用于在文本中指代这样的产品时：（1）将 4.0 版本（或更高）蓝牙核心规范和基于通用属性概要 (GATT) 的体系架构结合起来（2）具有双模式低耗能无线标准特征（例如，低耗能无线电和 BR / EDR 无线电，两者都能被激活）（3）使用 GATT 基体系架构为终端用户提供一种可以在 Bluetooth Smart Ready 设备上为 Bluetooth Smart 设备升级功能的方法，描述性词组 “Smart Ready” 可以与属性术语（如设备、产品、耳机、心率监测仪、键盘等）一起使用放于蓝牙文字商标之后，取代 “无线技术” 这一词组。同样地，注册商标符号 “®” 应该以上标格式紧跟在 Bluetooth 之后，且位于蓝牙文字标识后面的描述性或属性术语的后面不能使用商标符号。当术语 “Smart Ready” 用于指代不满足本段首句中所述要求的产品时，不能跟在蓝牙文字商标之后。可参考 21-25 页错误：Bluetooth smart ready® 手机错误：Bluetooth® Smart Ready™ 设备正确：Bluetooth® smart ready 电视正确：Bluetooth® Smart Ready 设备

With solder mask defined pads, theoverlap of the solder mask on the land creates a step in the solder at the land interface, which can causestress concentration and act as a point for crack initiation.■CSR recommends that the PCB land pattern to be in accordance with IPC standard IPC-7351.■Solder paste must be used during the assembly process.3.5Typical Solder Reflow ProfileSee Typical Solder Reflow Profile for Lead-free Devices for information._`SNRM=nckData Sheet4Bluetooth Modem4.1RF Ports4.1.1RF_N and RF_PRF_N and RF_P form a complementary balanced pair and are available for both transmit and receive. On transmit their outputs are combined using an external balun into the single-ended output required for the antenna. Similarly,on receive their input signals are combined internally.Both terminals present similar complex impedances that may require matching networks between them and the balun. Viewed from the chip, the outputs can each be modelled as an ideal current source in parallel with a lossy capacitor. An equivalent series inductance can represent the package parasitics.G-T W-03349.2.2RF_NRF_PFigure 4.1: Simplified Circuit RF_N and RF_PRF_N and RF_P require an external DC bias. The DC level must be set at VDD_RADIO.4.2RF ReceiverThe receiver features a near-zero IF architecture that allows the channel filters to be integrated onto the die. Sufficient out-of-band blocking specification at the LNA input allows the receiver to be used in close proximity to GSM and W‑CDMA cellular phone transmitters without being desensitised. The use of a digital FSK discriminator means that no discriminator tank is needed and its excellent performance in the presence of noise allows BC6150 QFN to exceed the Bluetooth requirements for co-channel and adjacent channel rejection.For EDR, the demodulator contains an ADC which digitises the IF received signal. This information is then passed to the EDR modem.4.2.1Low Noise AmplifierThe LNA operates in differential mode and takes its input from the shared RF port.4.2.2RSSI Analogue to Digital ConverterThe ADC implements fast AGC. The ADC samples the RSSI voltage on a slot-by-slot basis. The front-end LNA gain is changed according to the measured RSSI value, keeping the first mixer input signal within a limited range. This improves the dynamic range of the receiver, improving performance in interference limited environments._`SNRM=nck Data Sheet4.3RF Transmitter4.3.1IQ ModulatorThe transmitter features a direct IQ modulator to minimise frequency drift during a transmit timeslot, which results in a controlled modulation index. Digital baseband transmit circuitry provides the required spectral shaping.4.3.2Power AmplifierThe internal PA has a maximum output power that allows BC6150 QFN to be used in Class 2 and Class 3 radios without an external RF PA.4.4Bluetooth Radio SynthesiserThe Bluetooth radio synthesiser is fully integrated onto the die with no requirement for an external VCO screening can, varactor tuning diodes, LC resonators or loop filter. The synthesiser is guaranteed to lock in sufficient time across the guaranteed temperature range to meet the Bluetooth v2.1 + EDR specification.4.5Baseband4.5.1Burst Mode ControllerDuring transmission the BMC constructs a packet from header information previously loaded into memory-mapped registers by the software and payload data/voice taken from the appropriate ring buffer in the RAM. During reception, the BMC stores the packet header in memory-mapped registers and the payload data in the appropriate ring buffer in RAM. This architecture minimises the intervention required by the processor during transmission and reception.4.5.2Physical Layer Hardware EngineDedicated logic performs the following:■Forward error correction■Header error control■Cyclic redundancy check■Encryption■Data whitening■Access code correlation■Audio transcodingFirmware performs the following voice data translations and operations:■A-law/µ-law/linear voice data (from host)■A-law/µ-law/CVSD (over the air)■Voice interpolation for lost packets■Rate mismatch correctionThe hardware supports all optional and mandatory features of Bluetooth v2.1 + EDR specification including AFH and eSCO.4.6Basic Rate ModemThe basic rate modem satisfies the basic data rate requirements of the Bluetooth v2.1 + EDR specification. The basic rate was the standard data rate available on the Bluetooth v1.2 specification and below, it is based on GFSK modulation scheme.Including the basic rate modem allows BC6150 QFN compatibility with earlier Bluetooth products.The basic rate modem uses the RF ports, receiver, transmitter and synthesiser, alongside the baseband components described in Section 4.5.4.7Enhanced Data Rate ModemThe EDR modem satisfies the requirements of the Bluetooth v2.1 + EDR specification. EDR has been introduced to provide 2x and 3x data rates with minimal disruption to higher layers of the Bluetooth stack. BC6150 QFN supportsboth the basic and enhanced data rates and is compliant with the Bluetooth v2.1 + EDR specification._`SNRM=nck Data SheetAt the baseband level, EDR uses the same 1.6kHz slot rate and the 1MHz symbol rate defined for the basic data rate. EDR differs in that each symbol in the payload portion of a packet represents 2 or 3 bits. This is achieved using 2 new distinct modulation schemes. Table 4.1 and Figure 4.2 summarise these. Link Establishment and Management are unchanged and still use GFSK for both the header and payload portions of these packets.The enhanced data rate modem uses the RF ports, receiver, transmitter and synthesiser, with the baseband components described in Section 4.5.Data Rate Scheme Bits Per Symbol ModulationBasic Rate 1GFSKEDR 2π/4 DQPSKEDR 38DPSK (optional)Table 4.1: Data Rate SchemesG-TW-0244.2.3Enhanced Data Rate Figure 4.2: BDR and EDR Packet Structure_`SNRM=nck Data Sheet。

华为蓝牙鼠标2代说明书

华为蓝牙鼠标2代说明书
华为鼠标连接电脑需保证鼠标已安装电池且打开蓝牙配对开关，电脑需支持蓝牙功能。

打开已安装电池的华为蓝牙鼠标的蓝牙配对开关，将其放置在电脑旁，之后打开电脑的蓝牙功能，选择华为鼠标进行配对连接即可。

具体操作如下：
本文以华为MateBook 14；Windows 10为案例进行讲解。

1.将华为鼠标的上壳打开，按照电池仓的正负极标识正确安装一节5号电池，并将鼠标底部的蓝牙配对开关拨至【ON】位置，此时鼠标处于蓝牙配对状态，且鼠标正面的LED灯会闪烁。

2.把鼠标放置在电脑旁边。

打开电脑，移动鼠标光标至屏幕右下角的【开始菜单】并点击打开。

之后在弹出的菜单中，点击【设置】选项进入【Windows设置】菜单。

3.在【Windows设置】菜单中，找到【设备】选项点击进入。

之后，点击【蓝牙和其他设备】，打开【蓝牙】开关。

4.点击该菜单上方的【添加蓝牙或其他设备按钮】，选择【蓝牙】，然后找到【HUAWEI Mouse】这一设备，点击该设备即可完成连接。

鼠标光电芯片

鼠标光电芯片光电芯片是一种集光学和电子技术于一体的器件，广泛应用于鼠标、光电直尺等设备中，其基本原理是通过光电二极管和激光二极管实现光电转换，并将光信号转化成电信号进行处理。

以下将对鼠标光电芯片进行详细介绍。

鼠标光电芯片具有高灵敏度、高分辨率、低功耗等特点，可实现对光照变化的自动调节，从而提高鼠标的工作效率和稳定性。

其工作原理主要分为两部分：光学传感和电子信号处理。

首先是光学传感部分，光电芯片通常采用的是红外线光电二极管和激光二极管，它们能够将鼠标底座下的光线转换成电信号。

当鼠标在使用过程中移动时，光线会照射到鼠标底部的光学传感器上。

这时，光线会被二极管吸收，并通过光电转换器将光信号转化为电信号。

通过不同的光学元件的作用，可以实现对光照强度和角度的测量，并进一步实现对鼠标移动的追踪。

其次是电子信号处理部分，鼠标光电芯片会将获得的电信号输入到芯片内部的处理电路中进行处理。

在处理电路中，电信号会经过放大、滤波、数字转换等处理，最终得到与鼠标移动相关的信息，如鼠标移动的速度和方向。

这些信息会被传递给计算机，从而实现对鼠标移动的准确感知和控制。

鼠标光电芯片的研发和制造需要一系列的技术和工艺，如光学设计、光电转换技术、电路设计等。

鼠标光电芯片的性能很大程度上取决于这些技术和工艺的先进性。

近年来，随着光学和电子技术的不断发展，鼠标光电芯片的性能不断提高，并在鼠标行业中得到广泛应用。

总的来说，鼠标光电芯片是鼠标中关键的组成部分，通过光学传感和电子信号处理实现对鼠标移动的感知和控制。

其高灵敏度、高分辨率和低功耗等特点，使得鼠标能够在不同的环境下快速、稳定地工作。

鼠标光电芯片的不断创新和发展，将为鼠标的性能提升和功能拓展提供更大空间。

BT401蓝牙模块HID版本条码枪键盘鼠标的补充说明

一、简介
BT401支持双模蓝牙，所以可以很轻松的支持蓝牙BLE。

因为支持了BLE，所有就支持了BLE的HID。

也就是蓝牙的键盘、鼠标设备
注意，这里BLE的HID是可以回连手机的
二、详细描述
2.1串口指令和测试的效果
1、AT+HD123456789aBcS其中：AT+HD是命令，123456789aBcS是需要发送的数据
2、其他所有的指令参考标准的即可，包括设置波特率，设置HID的蓝牙名等等操作，这里我们已经屏蔽掉了蓝牙音频部分。

2.2硬件说明
1、这里拿出模块的PC1脚位，也就是模块的14脚，未连接输出高电平，连接成功输出低电平
2、其他不用的引脚直接悬空即可
3、模块广播中，功耗在22ma。

连接成功之后保持在10ma。

如果需要更低功耗，则需要关闭模块供电。
