很明显下一个目标是HeadsetService,直接看具体实现,这部分代码跳转都比较清晰,下面代码会先判断当前状态是否正确,关于HeadsetStateMachine几个状态可以参持这个/packages/apps/Bluetooth/src/com/android/bluetooth/hfp/HeadsetStateMachine.java的最前的代码注释。 boolean connectAudio() { // TODO(BT) BLUETOOTH or BLUET...

for (LocalBluetoothProfile profile : mProfiles) { if (connectAllProfiles ? profile.isConnectable() : profile.isAutoConnectable()) { if (profile.isPreferred(mDevice)) { ++preferredProfiles; connectInt(profile);//连接在这里, } } } ... connectInt的实现很简单,直接跳过看里面的profile.connect(mD...
Log.i(TAG,"Failed to connect "+ profile.toString() +" to "+ mName); } 这个方法中,profile.connnect(),直接调用 HeadsetProfile的connnect(),其实headset/handsfree 是共用同一个service。 packages/apps/Settings/src/com/android/settings/bluetooth/HeadsetProfile.java ...
Because our reference board hardware strict(the PCM IO has not pined out), so the HFP HF role has not enabled. If you want to enable it, you should enable PCM pin out first in hardare design. 0 Kudos Reply 03-10-2015 11:52 PM 1,950 Views stevenshi Contributor I hi Tao:...
By default, to use Connection Manager for establishing a data connection over Bluetooth Dial-up Networking (DUN), you must also include the Bluetooth Hands-Free Profile (HFP) (SYSGEN_BTH_HF) and Bluetooth Pairing Service (SYSGEN_BTH_PAIRSVC) operating-system (OS) components in your OS design...
SYSGEN_BTH_AG When this variable is set, the Bluetooth HS/HF and Audio Gateway Service Catalog item is included in the OS design. The functionality associated with this Catalog item supports the Headset Profile (HSP) and the Hands-Free Profile (HFP). SYSGEN_BTH_HID_KEYBOARD When this variabl...
