Latest Bluetooth RF test specification reduces test efforts

About Bluetooth® qualification

The Bluetooth wireless technology allows convenient and secure connectivity over short distances in smart devices such as mobile phones, laptops, medical devices, wearables, smart home devices etc. To enable market access such Bluetooth devices have to meet both regulatory and Bluetooth Special Interest Group (SIG) requirements.

Complying with the Bluetooth SIG Qualification Program means that devices (end-products, subsystems or components) meet a certain level of quality standards and interoperability. This is necessary to obtain the Bluetooth trademark and a pre-condition of the intellectual property license for using the Bluetooth technology.

7layers, a Bluetooth Qualification Test Facility (BQTF), is recognized by the Bluetooth SIG as being competent to perform Bluetooth qualification tests, including RF tests, Protocol and Profile Conformance tests and Profile Interoperability tests. In this role we keep a strict eye on all changes to the test specifications that have to be followed when aiming for Bluetooth Qualification.

New Bluetooth RF test specification becomes active

Today we would like to inform you, that by 14 October 2015 the Bluetooth RF test specification 4.2.1 becomes active (according to TCRL 2015-1), with the most significant change based on the test specification errata 6139. Due to this change, the requirements for “extreme test conditions” have been reduced considerably:

So far

  • 16 test cases for Bluetooth Basic Rate and Bluetooth Enhanced Data Rate (EDR) had to be performed under extreme test conditions regarding temperature and voltage.


  • All test cases covering testing under extreme voltage conditions have been removed.
  • Only 4 test cases remain that have to be assessed under extreme temperature conditions, covering sensitivity and output power tests.

Consequences for Bluetooth device qualification

This reduction in required extreme condition testing further eases the Bluetooth Qualification process and the market can now benefit from a growing amount of Bluetooth devices coming to market ever more quickly.

However manufacturers and suppliers should be aware that it is the Bluetooth member who has the ultimate responsibility to ensure that the qualified product complies with the Bluetooth specifications.  Passing the Bluetooth Qualification Process does not automatically guarantee full compliance, as only certain aspects are being assessed. Bluetooth members who want to safeguard that their devices really satisfy end user requirements may benefit from an extended quality assurance testing, 7layers can offer on demand.
