BQB is the Bluetooth SIG's product certification. To use the Bluetooth trademark and related wording – you must complete this certification. It is not a government‑mandated access – but an industry‑alliance certification. However, overseas e‑commerce platforms and offline clients generally require it – without it, normal sales are difficult.

In 2025, SIG introduced new DSM (Software Management) rules – targeting firmware‑upgradable Bluetooth devices – with stricter firmware‑version and software‑identifier controls. Factor this into project scheduling – otherwise, late‑stage listing rejections waste all previous testing – delaying product launches.

1. Timeline Differences – Two Paths

BQB has two main paths – QDL listing and QDID whole‑product testing – timelines and costs differ significantly. Choosing the wrong path wastes money – and 2–3 weeks of rework – get it right upfront.

1.1 QDL listing

·Product uses a BQB‑certified Bluetooth module – with module manufacturer authorisation – without changing the protocol stack or core RF design.

·Normal timeline: 2–3 weeks.

Important:

·The old EPL listing path is no longer accepting new projects – only legacy projects may be maintained.

·Antenna changes are not allowed – minor matching‑circuit adjustments may be submitted with a difference statement.

·Changing antenna type or gain invalidates QDL eligibility.

·No manufacturer authorisation letter = SIG rejection.

1.2 QDID test certification

·Using an uncertified module – or changing the RF/protocol core – requires whole‑product testing and QDID application.

·Testing + official review: typically 4–8 weeks – longer with complex Profile features.

·Reserve sufficient time – expedited review resources are scarce.

  2. QDID Self‑Test Path – Stage‑by‑Stage Timeline

Stage 1: Membership and DID application (3–7 days)

·Project requires SIG membership or DID purchase.

·Membership selection should be based on annual certification volume – blind choices increase overall costs.

SIG adjusted fees in March 2026:

·New product listings under the same company's own QDID are free.

·Only cross‑company external module QDID references require DID purchase.

Stage 2: Testing and scheduling (2–5 weeks)

·Labs run full Bluetooth tests – RF, protocol stack – based on actually enabled Profiles.

·First‑pass formal‑test rates are not high.

·Skipping pre‑testing: if failures occur – remediation easily adds 1–2 months.

·Pre‑testing is a practical risk‑reduction measure – not recommended to skip.

Stage 3: Submission and listing (1–2 weeks)

·After test reports are compiled – submit to SIG.

·Upon review – QDID is issued – product entered into the SIG database.

·Most delays come from report defects or internal document inconsistencies – upfront document checks enable first‑pass approval.

  3. Key Variables Affecting Timeline

·In‑vehicle and multi‑mode composite Bluetooth devices – test workload increases significantly – schedule buffer is essential.

·Many delays come from sample delivery delays or internal document‑parameter errors – not lab queues.

Profile coverage: only actually enabled Profiles need testing – don't cut tests to save cost. If channel audits find discrepancies between functionality and reports – products are delisted – losses far exceed test costs.

  4. Certificate Validity and Changes

·QDID has no fixed expiry – valid as long as the underlying Bluetooth design is unchanged and membership is active.

·QDL listing is tied to the specific module – if the module's core design changes – the listing cannot continue.

·Cosmetic or peripheral‑circuit changes: generally no re‑certification.

·Chip changes or major protocol‑stack version changes: re‑assessment required.

·Adding new Profile functionality: difference filing – not full retesting.

Always retain full technical archives – for alliance audits.

  5. BlueAsia's End‑to‑End Approach

BlueAsia handles BQB certification – and can coordinate with Wi‑Fi Alliance, FCC, and CE for integrated compliance planning. We assist with membership selection, pre‑testing, formal testing, and submission/listing. We get involved at the module‑selection stage – determining QDL vs. QDID – helping multi‑wireless products control overall project timelines.

  6. Common Misconceptions and Practical Reminders

·With purchased modules – do not modify antennas or RF circuitry without checking SIG rules – otherwise listing is invalid.

·Membership selection: don't just look at single‑quote prices – calculate total cost based on annual certification volume.

·Don't skip pre‑testing – the scheduling losses from formal‑test remediation far exceed pre‑test costs.

·DSM rules apply only to firmware‑upgradable Bluetooth devices – not all products.

·QDL listing requires module manufacturer authorisation – missing documents = review rejection.
