蓝牙 Gatt 问题 onClientConnectionState() - status=8 clientIf=29 [英] Bluetooth Gatt issue onClientConnectionState() - status=8 clientIf=29
本文介绍了蓝牙 Gatt 问题 onClientConnectionState() - status=8 clientIf=29的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在制作安卓 BLE 应用程序.根据文件，我提出申请.我的问题是，有时应用程序会运行良好，但有时会抛出错误.有 2 个日志，一个用于成功，第二个用于错误.每次蓝牙断开连接时，我都会发送关闭方法.我不知道我卡在哪里了.
第一个成功日志

出现的问题由我解决.
我看到有很多与连接到设备时出现的状态 8 和 22 相关的问题.我是说这是状态 8 和 22 的确切答案，但在某些情况下，这将是原因.
发生这种情况是因为当我们成功发现服务时，我们编写描述符并立即调用ondescripte覆盖方法，然后进行读写操作.那么会发生什么，不执行一个进程可能会产生这些问题.
我找到的解决方案非常有效.总是尝试制作Looper Handler，这样我就可以延迟完成一次执行.
new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {@覆盖公共无效运行(){mBluetoothGatt.writeDescriptor(RTS_CCCD);//对于描述符// 或者mBluetoothGatt.readCharacteristic(brspInfo);//读取//或者mBluetoothGatt.writeCharacteristic(brspInfo);//写}}, 500);状态 8 问题的原因和内容此处.>
为什么和什么状态 22 问题 这里.
I am making android BLE app. As per the Documents, I make application. My Problem is that sometime the app will work good , but sometime it throw the errors .There is 2 logs, one for success and 2nd for the errors. Every time bluetooth disconnect, i am send close method. I don't know where I am stuck.

As in above Logs , the 1st display the data but in 2nd i got the issue of status 8 , it will happen after 3 or 4 successful connection .My thought is that, If there is issue in the code then it is not given me single success connection.

解决方案
The issue that happens is resolved by me.
I have seen there are many question related to status 8 and 22 that occurs when we connect to device. I am saying that this is exact answer for status 8 and 22, but in some case it will be reason.
This happens because when we successfully discover the services, we write the descriptor and immediately call the ondescripte override methods and then read and write operation. So what happen, duw to not excecution of one process may create these problems.
The solution that I have found is working great. Always try to make Looper Handler, so that I make some delay to complete one execution.
new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {
@Override
public void run() {
mBluetoothGatt.writeDescriptor(RTS_CCCD); //for descriptor
// or
mBluetoothGatt.readCharacteristic(brspInfo); //for read
//or
mBluetoothGatt.writeCharacteristic(brspInfo); //for write
}
}, 500);
Why and what status 8 issue here.
Why and what status 22 issue here.
