BLE配对失败 [英] Ble pairing failed
问题描述
我参与一个Android应用程序，它确实BLE连接和对接公司BT芯片。该APP是BLE中心作用，而Bt基因芯片是BLE外设的角色。
I was involved an Android APP which does BLE connection and pairing with our company Bt chip. The APP is as BLE central role, while the Bt chip is as BLE peripheral role.
在该应用中使用Android 4.4或5.0智能手机上运行的BLE连接和配对效果很好。当应用程序在Android 5.1或6.0的最新版本上运行，BLE配对是由错误code终止（错误code：13），而BLE连接成功。下面是空的日志：
When the APP runs on Android 4.4 or 5.0 smart phone, the BLE connection and pairing works well. When the APP runs on Android 5.1 or the latest version 6.0, BLE pairing is terminated by error code (error code: 13), while BLE connection is succeed. Here is the air log:

我的转Bt基因宿主程序（基于转Bt基因芯片）收到 CONNECTION_PARAMETER_UPDATE_COMP_IND 事件，然后收到 LE_DEVICE_DISCONNECT_COMP_IND 事件。我想断开操作 BLE 由Android的转Bt基因栈完成。
My Bt host program (based on Bt chip) received CONNECTION_PARAMETER_UPDATE_COMP_IND event, and then received LE_DEVICE_DISCONNECT_COMP_IND event. I guess the operation of disconnect BLE is done by Android Bt stack.
在Android 4.4或5.0，有没有收到 CONNECTION_PARAMETER_UPDATE_COMP_IND 事件，那么什么是关于它的事情，我怎么可能在Android 5.1或6.0 BLE配对成功。任何帮助将AP preciated。
In Android 4.4 or 5.0, There is no CONNECTION_PARAMETER_UPDATE_COMP_IND event received, So what's the matter about it, how could I make BLE pairing success on Android 5.1 or 6.0. Any help will be appreciated.
推荐答案
有关蓝牙低功耗设备的发现和配对有被支持的两种方式。
For Bluetooth low energy devices finding and pairing there is two ways is being supported
-
对于奇巧版本并低于
startLeScan()
此方法需要一个 BluetoothAdapter.LeScanCallback 作为参数
This method takes a BluetoothAdapter.LeScanCallback as a parameter
对于棒棒糖版本以上
mBluetoothLeScanner = mBluetoothAdapter.getBluetoothLeScanner();
mBluetoothLeScanner.startScan(filters, settings, mScanCallback);
和你需要定义你的回调为流得到响应
and you need to define your callback as flow to get response
private ScanCallback mScanCallback = new ScanCallback() {
@Override
public void onScanResult(int callbackType, ScanResult result) {
}
@Override
public void onBatchScanResults(List<ScanResult> results) {
}
@Override
public void onScanFailed(int errorCode) {
}
};
