The last test connected to the wrong bdaddr, it should be

00:1A:45:4A:EA:39(jabra bt125). I tested this case again but data misalignment

exception asserted, the error message as follows:

root:/> aplay -D headset 0.wav

headsetd[248]: Configuration phase ended: target bdaddr is 00:1A:45:4A:EA:39,

timeout is 6000 ms

headsetd[248]: Changing state: Idle-->Paging
