Bluetooth Reassessment test is a rare project, one is limited by the small number of chip companies doing test certification, and the other is limited by the team with experience,the test will also involve the Bluetooth protocol layer.

In the whole process, thanks to the efforts of the technicians of both parties, according to the test requirements of the latest TCRL-2021, we tested all the mandatory case generated on the Testplan, and located the Event items that failed in the signaling interaction process against the test standards.
After several rounds of testing and debug cycles,confirming that all the mandatory test case have passed, the test log is finally submitted, and after being approved, QDID is locked again, and published in Bluetooth SIG official website,successfully complete the whole project.
Test cases list
The Bluetooth chip, as a key component of the Bluetooth industry chain, most of the certification type choices is ’Component’, and can be combined by downstream end products companies to form a their own QDID. However, the validity period of Component is limited, usually 3 years, and it needs to be Reassessment after 3 years.
The process is exactly the same as a new chip, but the only small difference is that the test case is a little less than the new chip, and the DID fee does not have to be paid again.

Controller case under test scene
Generally speaking, we call the implementation code of a protocol as Bluetooth Protocol Stack, and the Controller and Host are the core components of the Bluetooth protocol. The current Bluetooth protocols are divided into two technical types: basic rate/enhanced data rate (BR/EDR) and low energy (LE).
All tested Bluetooth protocol layers listed of this project
Deeplight has assisted many chip manufacturers to complete the testing of Bluetooth single and dual-mode BREDR-BLE chips, often involving the key protocol layers such as Baseband Conformance, Link Manager, HCI, Low Energy Link Layer, Isochronous Adaptation Layer and Security Manager Protocol.
