A: It was the first time that application of Bluetooth product certification required for RF, Protocol and Profile test referencing Qualified Design Listings (QDL). The Bluetooth product generally should test RF and Profile, if the Bluetooth module has been certified and its Qualification Design ID (QDID) within the validity period, you could just give the module QDID to test laboratory that proved this module don’t have to test Protocol again. And if you want to change the Bluetooth product shape, you could do the test referencing end-user product list (EPL), EPL can save certification fee that you pay for Bluetooth SIG, but you should still do the RF and Profile test.
