Yes, by design it is duplex so both sink and source works simultaneously, perhaps you are talking about of sending the microphone data to the other end which has probably nothing to do with Bluetooth but with audio routing not being properly configured. -- Luiz Augusto von Dentz ��.n��������+%������w��{.n�����{��� �^n�r������&��z�ޗ�zf���h���~����������_��+v���)ߣ�
