4.3 TEST GROUPS

The test groups are organized in 3 levels. The first level defines the protocol groups representing the protocol services. The second level, separates the protocol services in functional modules. The last level in each branch contains the standard ISO subgroups BV and BI (not shown in Figure 4.3 on page 12).

4.3.1 Protocol groups

The protocol group identifies the kind of test for Bluetooth RF test purposes: ?Transmitter

?Transceiver

?Receiver

4.3.2 Main test group

The main test groups are the capability group, the valid behavior group and the invalid behavior group.4.3.2.1 Capability (CA) tests

This sub group provides testing of the major EUT capabilities aiming to insure that the claimed capabilities are correctly supported, according to the ICS.4.3.2.2 Valid Behavior (BV) tests

This sub group provides testing to verify that the EUT reacts in conformity with the Bluetooth standard, after receipt or exchange of a valid Protocol Data Units (PDUs). Valid PDUs means that the exchange of messages and the content of the exchanged messages are considered as valid.B l u e tooth ED R R F Te st Su i t e Structur e

BLUETOOTH TEST SPECIFICATION Ver. 1.2/2.0/2.0 + EDR/2.1/2.1 + EDR page 13 of 72 Radio Frequency

4.3.2.3 Invalid Behavior (BI) tests

This sub group provides testing to verify that the EUT reacts in conformity with the Bluetooth standard, after receipt of a syntactically or semantically invalid PDU.

4.3.3 Conformance

When conformance to this profile is claimed, all mandatory features, as well as optional and conditional capabilities for which support is indicated in the ICS, are subject to verification as part of the Bluetooth qualification program.

A single successful test experiment may not constitute a pass verdict. In order to provide a foundation for interoperability it is necessary that a qualified prod-uct consistently and repeatedly pass any of the mandated tests.

If a member finds an issue with the test case as described in the test specifica-tion, or has issues with the utilized test system, the member is required to notify the responsible party with an errata request such that the issue may be addressed.

4.4 PROVISIONAL RF TESTING

Certain deviations from the test procedures shall be permitted for an interim period, as specified in Section 6.2, ’Provisional RF Testing (EDR)’ on page 63. Test Suite Structure27 December 200613

BLUETOOTH TEST SPECIFICATION Ver. 1.2/2.0/2.0 + EDR/2.1/2.1 + EDR page 16 of 72 Radio Frequency

?Initial Condition

a)EUT is connected to the tester via 50 ohm connector or a

temporary 50 ohm connector or if there is no antenna connector,

via a suitable coupling device.

b)EUT in test mode loop back or TX mode.

c)Hopping on.

d)If EUT supports power control the tester sets the EUT's output

power setting to maximum using LMP commands.

?Test Procedure

a)Tester transmits longest supported DM or DH packet with full

payload (1, 3 or 5 slot) with PRBS 9 as payload to the EUT. (See

“Reference Signal Definition” on page61.)

b)The spectrum analyzer settings shall be as follow:

- Center frequency: the lowest operating frequency

- Span: Zero Span

- Resolution Bandwidth: 3 MHz

- Video Bandwidth: 3 MHz

- Detector: Peak

- Mode: Maxhold

- Sweeptime: depending on packet type (one complete packet)

- Trigger: extern (to signalling unit.)

c)The first time the EUT transmits a burst on the spectrum analyzer

center frequency it is triggered to make a sweep over the duration

of the burst.

d)The tester records the highest power value P PK in the trace.

e)Tester calculates average power P AV over at least 20% to 80% of

the duration of the burst (position of p0 defines the begin of the

burst)

or

if the measuring system is not able to determine the p0 bit in the

burst:

Tester calculates average power P AV over at least 20% to 80% of

the duration of the burst. (The duration of the burst is the time

between the leading and trailing 3 dB points compared to the

average power).

f)Repeat b) to e) while the analyzer centre frequency is set to:

the mid operating frequency; and the highest operating frequency.

These frequencies are defined in Section 6.3.2, ’Frequencies for

testing, loopback, hopping off’ on page 63.

NOTE: When using test equipment that can follow the hopping sequence the low, mid, and upper frequencies can be tested when hopped to.

g)Repeat step a) to f) for all country specific hopping modes.

h)Step a) to g) is repeated under extreme test conditions.

i)The antenna gain G (in dBi,) is added to the results (in dBm)

measured in part a) to i) (only for verdicts 1) and 2) in Section ?,

’Expected Outcome’ on page 18.)

?Test Condition

This test case must be performed at normal and extreme test conditions. Test Purposes (TP)27 December 200617

BLUETOOTH TEST SPECIFICATION Ver. 1.2/2.0/2.0 + EDR/2.1/2.1 + EDR page 18 of 72 Radio Frequency

?Expected Outcome

All values as measured must fulfil the following conditions.

1.P AV < 100 mW (20 dBm) EIRP

2.P PK < 200 mW (23 dBm) EIRP

3.If the EUT is a power class 1 equipment:

P AV > 1 mW (0 dBm)

4.If the EUT is a power class 2 equipment:

0.25 mW (-6 dBm) < P AV < 2.5 mW ( 4 dBm)

5.If the EUT is a power class 3 equipment:

P AV < 1 mW (0 dBm.)

?Notes

In the ETS 300 328 the measurement method based on a combination with diode detector and oscilloscope is described. This measurement method is not up to date. An equivalent method for a Bluetooth device based on a spectrum analyzer can be used as described in the previous chapter.

The test case should be performed using loopback mode. If so, the test sys-tem must ensure that the testcase is not failed due to not correctly recog-nized return packets or payload failure, i.e: The test system must provide a means to check the correct packet type. In addition it is recommended that the payload content is checked as well if required.

However, if it is required and the test system does not provide a means to distinguish packet types, the TX mode might be used instead if supported by both, test system and IUT.

1.2 发射(transmitter)指标 1.2.1发射功率 定义:发射机载波功率是指在一个突发脉冲的有用信息比特时间上内,基站传送 到手机天线或收集及其天线发射的功率的平均值。 测量目的:测量发射机的载波输出功率是否符合GSM规范的指标。如果发射功 率在相应的级别达不到指标要求,会造成很难打出电话的毛病,即离基站近时容易打出而离基站远时打出困难,往往表现出发射时总是提示用户重拨号码。如果 发射功率在相应的级别超出指标的要求,则会造成邻道干扰。 测试方法: 手机发射部分由发射信号形成电路、功率放大电路、功率控制电路三个单元组成。 GSM频段分为124个信道,功率级别为5----33dBm,即卩LEVEL5--LEVEL19共15 个级别;DCS频段分为373个信道(512----885),功率级别为0----30dBm,即LEVEL0---LEVEL15共15个级别;每个信道有15个功率等级,测试时选上、中、下三个信道对每个功率等级进行测试,每个功率等级以2dBm增减。 功率控制:由于手机不断移动,手机和基站之间的距离不断变化,因此手机的发射功率不是固定不变的,基站根据距离远近的不同向手机发出功率级别信号,手机收到功率级别信号后会自动调整自身的功率,离基站远时发射功率大,离基站 近时发射功率小。具体过程如下:手机中的数据存储器存放有功率级别表,当手 机收到基站发出的功率级别要求时,在CPU的控制下,从功率表中调出相应的 功率级别数据,经数/模转换后变成标准的功率电平值,而手机的实际发射功率经取样后也转换成一个相应的电平值,两个电平比较产生出功率误差控制电压,去调节发射机激励放大电路、预放、功放电路的放大量,从而使手机的发射功率调整到要求的功率级别上。 测试指标: DCS1 800 Power con trol Nomi nal Output Toleranee (dB) for con diti ons

高通蓝牙测试方法(支持BT4.0测试)

高通蓝牙测试方法(支持BT4.0测试) 1,将ADB文件copy到电脑上D盘根目录下 2,正常开机并用USB线连到PC,手机端注意”设置”->”应用程序”->”开发”->”USB调试” 打钩。此时蓝牙不用打开,后续ADB指令能够控制蓝牙进入Slave模式。 3,开始菜单->运行->输入“cmd”进入Command窗口,输入“D:”后回车 4,在Command窗口中运行“CD platform-tools”进入ADB文件夹 5,在Command窗口中运行adb.exe,出现如下界面 6,输入“adb root”指令,进入root权限,会跳出如下窗口: 7,再输入“adb shell”,跳出一个“#” 8,依次输入如下指令(可逐行copy运行) bdt enable dut_mode_configure 1 这时蓝牙便进入测试模式,可以用仪器对蓝牙发起呼叫,从而完成BT2.1的测试。

若需要测试BT4.0,还需在信道ch0和ch39上进行发射,包括调制信号和单载波的发射。可通过如下指令实现: 1,重启手机后,输入“adb root”,进入root权限,会跳出如下窗口: 2,再输入“adb shell”,跳出一个“#” 3,输入“btconfig /dev/smd3 rawcmd 0x08 0x001E 0x00 0x25 0x00”,在信道0上进行BLE发射

蓝牙模块使用说明书

蓝牙模块使用说明 一、模块简介: 1、芯片简介 该蓝牙模块采用台湾胜普科技有限公司的BMX-02X模块为核心,它采用CSR BLUEcore4-External芯片并配置8Mbit的软件存储空间,成本低,使用方便。 CSR BlueCore4是英国Cambridge Silicon Radio(CSR)公司日前推出的第四代蓝牙硅芯片。这种硅芯片用于蓝牙技术推广小组(SIG)推出的增强数据传输率(EDR)蓝牙。CSR的BlueCore4的数据传输率将比现有的v 1.2蓝牙装置快三倍,并且使蓝牙移动电话或手机的耗电量较低。 蓝牙EDR的最大数据传输率为每秒2.1兆比特,而目前v1.2标准传输率则为每秒721千比特。传输率的提高意味着对一个特定量的数据来说,EDR无线电的工作将比v1.2无线电快三倍,从而减少耗电量,大大有利于依赖蓄电池的移动设备。 CSR BlueCore4完全能与现有蓝牙v1.1和v1.2装置兼容。蓝牙EDR用一种相移键控(PSK)调制模式取代标准传输率的Gaussian频移键控(GFSK),实现更高的数据传输率。 CSR BlueCore4正在以两种形式提供——一种用于外部“快闪”存储器,一种用于掩模ROM。BlueCore4-External以一种8×8mm BGA(球形格栅矩阵)封装提供,是十分灵活的解决方案,能够适应迅速更新的市场。例如,由于BlueCore

是目前可以得到的唯一能够支持蓝牙v1.2规格的所有强制和可选功能的硅芯片,BlueCore4-External为PC应用程序提供了理想的解决方案,使它们得益于以三倍速度的传输率无线传输文件,或者同时操作多个高需求的蓝牙链路。 鉴于蓝牙固件安装在芯片只读存储器上,CSR BlueCore4-ROM 的成本较低,占用面积小得多(在小片尺寸包装中为3.8×4mm,在与BC2-ROM和BC3-ROM引脚兼容的BGA中为6×6mm)。ROM芯片的尺寸和成本使它日益成为要求蓝牙功能综合起来的移动电话、手机和其它批量生产和成本敏感的应用产品的选择。 BlueCore4提供48KB的RAM,而以前的BlueCore硅芯片仅为32KB。部分这种额外的记忆存储用于对付增强数据传输率的附加缓冲空间,而其余部分则确保象Scattermode这样的未来规格得到充分支持。 BlueCore4-External和BlueCore4-ROM将先把蓝牙EDR快速数据传输率的优越性带给现有一些主要的蓝牙市场,加快文件传送,降低耗电并实现多个同时链路的操作。它还将为这种技术开辟某些潜在的新应用领域。 2、主要特性 ◆蓝牙版本:V2.0+EDR ◆输出功率:class II ◆Flash存储容量:8Mbit ◆供应电压:5V

蓝牙模块学习笔记(1)

蓝牙模块学习笔记(1)

蓝牙模块学习 刚拿到蓝牙模块,心中有点小激动啊; 民用级:HC-05,HC-06(HC-06-M,HC-06-S) HC-05-D,HC-06-D(是带底板的模块,主要是用户用于测试和评估) 本文介绍的为HC-06蓝牙串口模块。 蓝牙串口模块用于把串口转换为蓝牙,这种模块工作的时候分为主机和从机,其中偶数命名的型号出厂时就确定了是从机或者是主机,并无法更改。奇数命名的型号可以用户自己通过AT指令修改模块为主机或者从机。 主机:HC-06-M , M=master 从机:HC-06-S , S = slaver 串口模块的使用,是不需要驱动的,只要是串口就可以接入,配对完毕即可通信,模块与模 块的通信需要至少 2 个条件: 1、必须是主机与从机之间 2、必须密码一致(密码:1234) 主机: 记忆最后一次配对过的从机,并只与该从机配对,直到KEY(26 脚)高电平触发时放弃记忆,26 脚默认应该接低电平。 配对方式: 主机自动搜索从设备进行配对。 典型方式:在一定条件下,主从之间自动配对 AT 模式:

配对前就是AT 模式,配对完毕后透明通信 图1 是HC-06 图片及主要引脚 现在你手中拿到的HC-06引出了四个引脚,分别为VCC、GND、TXD、RXD。四个引脚分别对应单片机的电源5V或3.3V;GND接地;TXD、RXD交叉连接(对应单片机的P3^0,P3^1)。 连接好,单片机上电,此时蓝牙模块上led闪烁,表示尚未连接其他蓝牙设备。此时用手机蓝

牙搜索,可以搜索到HC-06.点击连接,输入pin 密码则可以连接。 连接好后,利用蓝牙串口助手就可以对蓝牙模块通信了,编程也就可以把蓝牙当作普通串口来对待。 注意编写好程序后,向单片机烧录时,必须将TXD、RXD拔出才能烧写!!! 问题:串口发送字符串时,最后没有标志可寻。可以将字符串接收到数组中,发送数据到12864,检测是否到’\0’,如果检测得到,将标识符flag 置为1;串口中断服务程序中,检测到flag为1时,这证明数据显示成功。此时应当清屏! 清屏方法:while(Tem[i]!='\0') { Tem[i]=' '; i++; }

蓝牙产品如何测试使用

蓝牙产品如何测试使用 文章来源:https://www.doczj.com/doc/7c11415913.html,/ l 进行手机蓝牙功能测试的大致过程:开启手机蓝牙功能—>搜索蓝牙设备/被动搜索—>主动认证/被动认证—>蓝牙各个功能测 试—>关掉手机蓝牙。 l 手机与蓝牙设备的认证:主动认证和被动认证,即发起配对请求和接受配对请求。 l 当手机处于蓝牙开启的状态时,可以进行蓝牙设备搜索,搜索到的设备会显示在列表中。测试者可以选择自己需要进行对抗 测试的设备,蓝牙设备可以是小巧的耳机,也可以是手机或者其 他蓝牙设备。 l 手机与蓝牙设备进行认证操作时,一般设备的匹配密码都是四个零,有个别的耳机会有区别。当耳机匹配密码为四个零时, 手机与其建立连接无需认证,直接配对即可。 l 当手机蓝牙开启并处于被搜索的状态,且手机设定为“一直可见”的话,其它蓝牙设备可以来找寻手机,这种方式就属于被 动认证。主动发起搜索,搜索其他蓝牙设备的过程为主动认证。 测试重点1:HF(Handsfree)--免提功能 l 首先手机蓝牙打开,并搜索设备,然后进行认证、连接。连接也分两种—主动连接和被动连接。通过蓝牙耳机可以进行接听 电话、挂断电话、拨打电话的操作,断开连接等。

l 测试来电:手机和耳机均可进行接听,拒绝操作,考虑来电话时蓝牙耳机是否有声音及被对方挂断时蓝牙耳机的反应。 l 测试呼出电话:手机和耳机(只能拨打最近的一个电话)均可进行拨出和取消操作,蓝牙耳机还有语音拨号功能;在通话过程中,可以进行电话和耳机的声音切换、保持和返回切换。 l 挂断电话:可以通过手机、蓝牙耳机或者对方挂断,可以在正常通话时挂断或者在保持状态是挂断。 l 断开服务连接:可以通过手机主动断开,也可以通过关掉耳机电源断开连接。 测试重点2:HS(Headset) 测试方法与HF类似。主要差别如下: l 在认证时只能从手机方认证。 l 不能拒绝来电。 l 通话时声音切换只能单方向切换。 l 从手机切换到耳机只能由手机方操作。 l 从耳机切换到手机只能由耳机方操作 测试重点3:A2DP-Advanced Audio Distribution Profile A2DP全名是Advanced Audio Distribution Profile 蓝牙音频传输模型协定! A2DP是能够采用耳机内的芯片来堆栈数据,达到声音的高清晰度。有A2DP的耳机就是蓝牙立体声耳机。声音能达到44.1kHz,一般的耳机只能达到8kHz。如果手机支持蓝牙,只要装载A2DP协议,就能使用A2DP耳机了
