Android 10:GATT错误133-如何解决? [英] Android 10: GATT error with 133 - how fix?

问题描述

我有android应用.我使用BLE(低功耗蓝牙)连接到设备.它工作正常，但在Android 10上却出现问题.这是我的代码:

I have android app. I use BLE(Bluetooth low energy) for connect to devices. It is work good, but I have issue on Android 10. This is my code:

 Hashtable<String, BluetoothDevice> myHtDevices;
 ....
 BluetoothGatt gatt = myHtDevices.get(deviceId).connectGatt(this, false, gattCallback);

在onConnectionStateChange中，我得到:

in onConnectionStateChange I get:

//public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState){
status= 133,
newStatus =0,

我只有Android Q这个问题.

I have this issue only Android Q.

我尝试了这种方法(添加了参数TRANSPORT_LE)，但是它不起作用:

I tried this method(add param TRANSPORT_LE), but it not work:

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.Q){
        gatt = myHtDevices.get(deviceId).connectGatt(this, false, gattCallback, 
     BluetoothDevice.TRANSPORT_LE);
    }
    else {
        gatt = myHtDevices.get(deviceId).connectGatt(this, false, gattCallback);
    }

添加信息:

1. 我通过执行BLE扫描来获取myHtDevices.

1. I get myHtDevices by performing a BLE scan.

我会立即回调.

有什么建议吗?

推荐答案

如

As seen in the AOSP constants, this error is the most generic error you can get. Generally, it happens when the device is out of range but you tried to connect anyway. You should check the full logcat & dmesg to find out the root cause. My BLE app fails to connect to any devices on Huawei phones running custom ROMs, so make sure that the device is on the OEM stock version of Android 10 - and if that doesn't work, try on AOSP instead - you never know what a manufacturer put in their skin.
