Then we want to connect that SEP to our SRC endpoint but it is actually not there. After that I realized that I told you to do "av connect" before actually "audio init" and that is wrong. "Audio init" does register your SRC endpoints. So you should do that and after that try "av connect" BR Lukasz >> >>> acl_state_changed_cb: status=BT_STATUS_SUCCESS >>> remote_bd_addr=24:fd:52:b6:a0:99 state=BT_ACL_STATE_DISCONNECTED >>>> >>>> D/BlueZ ( 1060): >>>> >>>> external/bluetooth/bluez/android/hal-bluetooth.c:handle_acl_state_changed() >>>> state 1 >>> >>> >> \Łukasz >> >>> On 2/11/2015 4:16 PM, Lukasz Rymanowski wrote: >>>> >>>> Hi Tony, >>>> >>>> On Tue, Feb 10, 2015 at 2:51 AM, Zheng Tao-B46827 >>>> wrote: >>>>> >>>>> Hi, Peers >>>>> >>>>> Thanks for your hard work that let us can experience BlueZ for Android. >>>>> But >>>>> I am faced with a audio/a2dp problems that stick me many weeks. >>>>> >>>>> I’m try to port Bluez to kitkat 4.4.3, and many common profiles, such >>>>> as >>>>> HIDP/FTP/GATT can function successfully.
