Hi Krishnan, > How do we qualify AVCTP and AVDTP? Not all test cases of these protocols can be simulated through AVRCP and A2DP. Any hints on qualifying these two protocols? Do we have some stubs to do these? you have to write a program that tests the valid and invalid test cases of AVDTP and AVCTP. Then the HCI or air traces have to be captured and evaluated by a BQE to proof correct behavior.
