U8903B Bluetooth Test Description
The U8903B Bluetooth card supports two Bluetooth audio profiles which are the Handsfree
Profile (HFP) and the Advanced Audio Distribution Profile (A2DP). The VEE test program is
used to test these two profiles for their functionality. The tests focus on profile connectivity
as well as audio generation and measurement functionality.
Handsfree Profile (HFP) test description
Figure 5-8 U8903B Bluetooth test for HFP profile (BT Role: Initator, Audio Role: AG)
– The first set of Bluetooth tests for the HFP profile is performed with the DUT’s Bluetooth
profile role configured as Initiator and the audio role configured as Audio Gateway.
– The HFP profile tests shown in Figure 5-8 are connectivity tests and consist of the
following:
– HFP_INT_AG_CVSD_Inquire, Pair & Connect
– HFP_INT_AG_mSBC(WB)_Disconnect & Connect
– HFP_INT_AG_Disconnect & Unpair
– The connectivity tests validates the functionality of the DUT's ability to perform inquiry,
pairing, unpairing, connection, and disconnection.
– The remaining HFP profile tests are the Bluetooth audio tests and consist of the
following:
– HFP GEN Test
– HFP ANA Test
– HFP GEN (WBs) Test
– HFP ANA (WBs) Test
–The Bluetooth audio tests are considered as subset tests that fall under the HFP profile.
The HFP Bluetooth pairing, profile connection, and audio connection have to be
successfully established before the Bluetooth audio tests can be performed.
