Advanced Audio Distribution Profile (A2DP) test description
Figure 5-10 U8903B Bluetooth test for A2DP profile (BT Role: Initator, Audio Role: SRC)
– The first set of Bluetooth tests for the A2DP profile is performed with the DUT’s
Bluetooth profile role configured as Initiator and the audio role configured as Source.
– The A2DP profile tests shown in Figure 5-10 are connectivity tests and consist of the
following:
– A2DP_INT_SRC_SBC_Inquire, Pair & Connect
– A2DP_INT_SRC_Disconnect & Unpair
– The connectivity tests validates the functionality of the DUT's ability to perform inquiry,
pairing, unpairing, connection, and disconnection.
– The remaining A2DP profile test is the Bluetooth audio test and consists of the
following:
–A2DP GEN Test
–The Bluetooth audio test is considered as a subset test that falls under the A2DP profile.
The A2DP Bluetooth pairing, profile connection, and media connection have to be
successfully established before the Bluetooth audio test can be performed.
–The Bluetooth audio test validates the audio functionality of the maximum A2DP audio
bandwidth (48 kHz sample rate) using the CVSD audio codec for the generator.
