Bluetooth trackers (such as anti-loss devices, item locators, etc.) must pass BQB certification to legally use the Bluetooth logo and ensure compatibility with other Bluetooth devices. The following are the core points of the BQB certification:
1. Core Basis of Certification
Bluetooth trackers are typically based on BLE (Bluetooth Low Energy) technology and must comply with Bluetooth core specifications (such as versions 5.0/5.1/5.2), focusing on basic functions such as broadcasting, scanning, and connection management, as well as possible extended features like Direction Finding (if supporting precise positioning).
2. Certification Process (consistent with other Bluetooth devices, focusing on BLE features)
Become a SIG Member
Companies must register as Bluetooth SIG members (such as Adopter level) to obtain a member account for submitting certification applications.
Determine Product Technical Parameters
Clearly specify the supported Bluetooth version (such as BLE 5.1), advertising interval, and transmission power level;
Indicate whether special features are supported (such as direction finding, long-range mode, encrypted transmission, etc.).
Select Authorized Laboratory for Testing
Testing must be conducted by a SIG -recognized laboratory, with core testing items including:
Radio Frequency Performance (RF): transmission power, receiving sensitivity, frequency accuracy, modulation accuracy, etc. (BLE devices have higher stability requirements for RF under low power);
Protocol Compliance: Verify whether BLE broadcasting, scanning, connection establishment / disconnection, data transmission processes comply with specifications;
Profile Compatibility: If supporting specific application profiles (such as Find Me Profile), functionality compliance must be tested;
Interoperability: Stability of pairing and data synchronization with mainstream mobile phones, tablets, etc. (such as the connection response speed between the APP and the tracker).
Submit Documentation and Review
Submit test reports, product technical documents, etc., to SIG , and upon approval, obtain a unique QDID (Qualification Design ID) and enter it into the SIG database.
Compliant Use of Bluetooth Logo
After certification, the official Bluetooth logo can be used on products, packaging, and promotional materials.
3. Key Documentation to Prepare
Basic Information of the Company and Product
SIG membership proof, business license (in Chinese and English);
Product model, name, and functional specification (clearly stating BLE application scenarios, such as anti-loss alarm, location reporting, etc.).
Technical Documentation
Circuit schematic (indicating BLE chip, antenna, power management module);
PCB layout diagram (focusing on the wiring and shielding design of the BLE RF section);
BOM list (must specify BLE chip models, such as Nordic nRF52840, Dialog DA14531, etc.);
Antenna parameters (gain, standing wave ratio VSWR, operating frequency band, BLE is typically 2.4GHz);
Firmware version description (including BLE protocol stack version, such as based on Zephyr, BLE Stack, etc.).
Testing Related Materials
Testing prototypes (3-5 units, must be consistent with the production version, including prototypes with test points for RF testing);
If using certified BLE modules, provide the module’s QDID and authorization proof (can simplify the testing process).
4. Precautions
Low Power Characteristics: Trackers typically rely on battery power, and testing must verify the stability of Bluetooth functionality in low power mode (such as connection recovery capability during sleep / wake-up).
Security and Privacy: If data encryption is involved (such as location information transmission), specify the encryption algorithm (such as AES-128) and implementation method to ensure compliance with Bluetooth security specifications.
Function Compliance: Trackers supporting direction finding features require additional testing for angle calculation accuracy, multi-device collaborative positioning compatibility, etc.
