1. Connect the headset/microphone to BM20
evaluation board’s audio out connector (P6) and MIC input
(P5) respectively.
2. Connect BM20 evaluation board to a smartphone that supports the A2DP and HFP/HSP Bluetooth
profiles.
3. From another one phone, initiate a call to the smartphone that is paired with BM20 evaluation board. The
A2DP stream pauses and the ringtone plays on the headset.

n “MFB” on BM20 evaluation board to accept the incoming call.
