一、简介

1、Basically it involves the certification of Bluetooth,都绕不开FCC和BQB这两个名词.简单理解如下：

(1)、FCCIt is used to test the performance of radio frequency

(2)、BQBis the protocol for testing bluetooth.

If the customer needs to be certified,It is best to consult a professional agency,We can only do our best to cooperate,But it can't replace the customer

2、注意：硬件上面,just do3件事情：

(1)、一定,To reserveUSB的两个脚,还有电源、地线.Please see the reference schematic for details

(2)、一定,要联系我们,Burn and authenticate the corresponding firmware

(3)、一定,要购买“USB转TTL”的工具.总之,不要担心,This is money,Things you can do with your time

3、Certification of Bluetooth products,只有3个环节

(1)、环节一：我们.Cooperate with customers to issue certification information、测试软件、工具.and coordinating corrections

(2)、环节二：贵司.出钱,出产品,Get certified with us

(3)、环节三：认证公司.They are paid for the report

Don't think about spending money on false reports.Any certification company that can take such a thing,都是坑,In the end, it must hurt your company

4、认证公司,We recommend agencies we have been working with,原因有二：

(1)、长期合作了,They are more cooperative,The fee will be relatively small discount

(2)、Physically close to our company,Once the test has failed,We can make timely corrections.even needed,You can go to the site to rectify.这样效率会很高

(3)、The certification company has no interest relationship with our company.Course certification costs,Your company can also compare in many ways

二、关于FCCcertification instructions

2.1 硬件的连接

拿到之后,什么都不用改,We are all wired up,Only two parts were used

1、A tool for communicating with a computer --- 简称USB转TTL

2、Client your target mockup,这个不用多说

2.2 Description of the software

1. what you need to do,Just install it on the computer“USB转TTL”的驱动程序.推荐使用CH340Gthe transfer board
2. Then open what we offerFCCFixed frequency test host computer software,如上图,波特率设置为115200
3. Then test institutions according to their needs,Test your own parameters
4. After each data is sent,The upper opportunity has the above“发送成功！”的反馈信息
5. 注意,If your product is not availableble ,Then the options box on the left,只用选择“BR/EDR”.BLEPart of it is directly ignored

备注：The prototype has entered the test mode,So he is no longer a complete functional product,仅做FCC测试用.The phone is also not connected

Bluetooth chipTX是USBDP ,RX是USBDM

USBDP[TX]  ----- Connect the serial port board ---》  RX

USBDM [RX] ----- Connect the serial port board --- 》 TX

2.3 FCCExample of actual board wiring for fixed frequency

接线如上.At the same time, we will also help customers to connect the wires in the above way.Of course you can wire it yourself,usbThe two lines are very important,

The premise is to upgrade the firmware first,请参考“20200218_FCC和BQB测试_9600波特率_升级文件BFU”

2.4 BQB测试说明

1、BQB的测试,It is also necessary to burn specific firmware into the Bluetooth chip,This needs our help.

2、烧录BQBAfter authenticating the firmware,The prototype does not require any jumpers.

3、The testing agency will have special instruments to analyze the Bluetooth protocol integrity and other parameters

4、How to tell if the prototype has entered BQB 测试模式？  

==》开机之后,用Mobile phone bluetooth search,搜到 BR21-RAM 蓝牙（点击连接,Not being able to connect is normal）.

It means that the machine has entered BQB 测试模式,Can be provided to testing companies for testing.

三、关于BQBcertification instructions

1  蓝牙SIG 规定

根据蓝牙SIG 最新规定,2018 Older versions are no longer availableBQB 证书.

past certification,It can be inquired online：Launch Studio - Listing Search

2  查询BQB 列名信息

打开网址后,Enter our company name“jieli”,点击“Enter”键,related information can be foundBQB 信息,如下图所示：

1. See our printed documentation for details

“Launch Studio - Listing Details_AC692x.pdf”

4、Detailed parameter information

5  How did the product goBQB 认证

     What we have done isEnd Product 类型的BQB,QDID 是110839.

     1）Customers are certified without re-testingProfile 和RF,节省时间和费用.

     1）First-time certified customers,You need to apply for an account on the Bluetooth official website.

     2）Customers with existing accounts,需要向SIG apply for a productDID.

     3）建立Test Plan When citing our companyQDID,Then fill in some information according to the actual product.

     4）You can apply for help through a laboratory agent,Some fees will apply.
