BQB certification is Bluetooth certification. In short, if your product has Bluetooth capability and has a Bluetooth logo on the product's appearance, you must pass a certification called BQB , a specific BQB See below.

    The essence of Bluetooth technology: A short-range wireless communication standard, working at 2.45GHz (2402-2480MHz) ISM band for a total of 79 Channels . Each transceiver is configured with a 48 bit address with a data rate of <1 Mbps using spread spectrum and frequency hopping techniques that The working range is about 10m-100m .

    To understand BQB certification you must first understand Bluetooth SIG ( Bluetooth Special Interest Group ) . 1998 In May, five world famous big companies - Ericsson, Nokia, Toshiba, IBM and Intel jointly launched the Bluetooth (Bluetooth) program, which has received response and support from many vendors. Bluetooth SIG Current members 9000 include Ericsson, Intel, Lenovo, Motorola, Microsoft, Nokia and Toshiba, the initial members of Promoter . In order to better develop the Bluetooth technology and ensure the compatibility of the interconnection operation of different equipment connections,Bluetooth SIG issued the Qualification Program Reference Document v2.0 (PR2 2.0 for short) to oversee the normative use of Bluetooth technology. Must be a Bluetooth SIG member; the product must be certified under the Bluetooth Qualification Process (BQP) > Logo. This requires that all Bluetooth products be BSP certified for sale and use.

BQBCertification process

    Must first become a Bluetooth SIG member with two separate members: Associate Paid member span>, the other is Adopter does not need paying members, according to the specific needs to apply for different types of membership.

Members must complete all steps required by PRD 2.0 . The Bluetooth qualification process is designed to better ensure interoperability, to verify compliance with Bluetooth specifications, to enforce Bluetooth SIG, and to correct the potential abuse of the trademark Bluetooth Provide members a higher test standard to demonstrate the stability and quality of their products working with other Bluetooth devices. The new program drives more efficient development of Bluetooth devices while automating the process by reducing the time it takes to qualify and reducing costs.

According to the type of test points, BQB test contains the following test items

RF Testing

Protocol Conformance Test

Profile Conformance Test

Profile Interoperability Test

    All test items are divided into A, B, C, D four , details are as follows:

    The test shall be performed on a test equipment meeting the following equipment requirements and the test shall demonstrate that the certification requirements should be met.                                                

Because Component , Chip , Module are all Pre-Qualified > End-Product requires testing only for RF and Profile .

    For End-Product , only RF is required if Component is authenticated, and IOP tests are mandatory Even if no other Profile is supported.

    The following table is one of the most simplified product certification process:
