Bluetooth BQB certification mainly includes two types: Listing Certification (EPL) and Testing Certification (QDID), with the following differences:
Applicable Scenarios
Listing Certification (EPL): Suitable for finished products that use certified Bluetooth modules, such as Bluetooth speakers and headphones that utilize certified modules from Nordic or TaiLingWei. As long as the finished product does not modify the Bluetooth functionality of the module, it can apply for Listing Certification.
Testing Certification (QDID): Suitable for unapproved Bluetooth modules or newly designed products, such as newly developed Bluetooth headphones, smartwatches, etc., as well as products that have undergone hardware or software modifications to certified modules that change their Bluetooth functionality.
Testing Requirements
Listing Certification (EPL): No need to repeat comprehensive tests for RF, protocol stack, etc.; only requires authorization from the module supplier and provision of relevant documentation to prove that the product uses a certified module.
Testing Certification (QDID): Requires completion of full testing, including RF performance tests such as transmission power, receiving sensitivity, etc.; protocol stack testing to verify the compatibility of the Bluetooth protocol stack; and profile testing to ensure the product complies with Bluetooth technical specifications.
Certification Process
Listing Certification (EPL): The process is relatively simple, generally taking about 2-3 weeks. First, the module supplier authorizes the DID number, then the applicant completes the listing registration on the SIG official website, submits relevant materials for review, and upon approval, the certification is completed.
Testing Certification (QDID): The process is more complex, taking about 4-6 weeks. The applicant must first register as a SIG member, then submit the certification application and product prototype to a SIG -approved laboratory for testing. After the laboratory completes the testing, it submits the report to the SIG for review, and upon approval, a certification certificate is issued.
