我正在使用“android.bluetooth.headset.action.VENDOR_SPECIFIC_HEADSET_EVENT”意图来获取特定于设备的AT命令。但是当我从MY Bluetooth Kit发送AT命令时，广播记录器没有触发。
当我从我的工具包中发送AT+CHUP\r时，android会在内部执行此命令并断开呼叫。
但是当我从套件中发送AT+XEVENT=foo,3\r但是我没有收到接收器中的任何东西。
帮帮我
答案 0 :(得分：6)
我也很难让特定供应商的耳机活动工作，但终于弄明白了。您必须将要接收的供应商特定事件类别添加到注册广播接收器时指定的IntentFilter。
添加
后filter.addCategory(BluetoothHeadset.VENDOR_SPECIFIC_HEADSET_EVENT_COMPANY_ID_CATEGORY+"."+BluetoothAssignedNumbers.PLANTRONICS);
我的接收器现在从蓝牙耳机获得供应商特定广播。 AT+XEVENT=foo,3\r
答案 1 :(得分：-3)
让您使用this ?
