Android的BLE GATT_ERROR（133）上的连接装置 [英] Android BLE GATT_ERROR(133) on connecting to device

问题描述

我试图连接到使用MAC地址的BLE设备。

  BluetoothDevice类设备= bluetoothAdapter.getRemoteDevice（rememberedDeviceAddress）
bluetoothDevice.connectGatt（背景下，假的，bluetoothGattCallback）;
 

我得到一个回调BluetoothGattCallback.onConnectionStateChange与状态= 133和newState = 2的甚至当我BLE装置处于关闭状态。

newState = 2是指BluetoothProfile.STATE_CONNECTED这意味着我正在连接到装置和状态= 133是GATT_ERROR（而不是状态= 0 SUCCESS）

我不明白在无法注册回调错误。

设备：一加一（Android 4.4系统）

这是什么可能导致此问题的任何指针将是有益的。

请注意：问题不所有的设备上发生的。一切似乎是工作在Nexus 5细跟的是Android 5.0

请找到堆栈跟踪如下：

  13 03-06：00：11.994：D / BluetoothGatt（26771）：registerApp（）
03-06 13：00：11.994：D / BluetoothGatt（26771）：registerApp（） -  UUID = UUID来这里
03-06 13：00：12.004：D / BluetoothGatt（26771）：onClientRegistered（） - 状态= 0 clientIf = 5
03-06 13：00：42.004：D / BluetoothGatt（26771）：onClientConnectionState（） - 状态= 133 clientIf = 5设备='设备ID来这里
 

解决方案

某些设备需要蓝牙LE的互动要在UI线程上运行。因此，我建议想是这样的：

  //创建主线程处理器，其中mContext是应用程序上下文
mHandler =新处理程序（mContext.getMainLooper（））;
...
//连接到从mHandler BLE装置
mHandler.post（新的Runnable（）{
@覆盖
公共无效的run（）{
    mBTGatt = mBTDevice.connectGatt（mContext，假的，mGattCallback）;
}
}）;
 

当然，你可以使用Activity.runOnUiThread为好。来源： http://stackoverflow.com/a/23478737

I am trying to connect to a BLE device using the MAC address.

BluetoothDevice device = bluetoothAdapter.getRemoteDevice(rememberedDeviceAddress)
bluetoothDevice.connectGatt(context, false, bluetoothGattCallback);

I get a callback in BluetoothGattCallback.onConnectionStateChange with status = 133 and newState = 2 even when my BLE device is switched off.

newState = 2 refers to BluetoothProfile.STATE_CONNECTED which means that i am connected to the device and status = 133 is GATT_ERROR (instead of status = 0 SUCCESS)

I do not get the Failed to register callback error.

Device : One plus one (Android 4.4)

Any pointers on what might be causing this issue would be helpful.

Note: Issue does not happen on all device. Everything seems to be working fine on Nexus 5 with Android 5.0

Please find below the stack trace:

03-06 13:00:11.994: D/BluetoothGatt(26771): registerApp()
03-06 13:00:11.994: D/BluetoothGatt(26771): registerApp() - UUID='uuid comes here'
03-06 13:00:12.004: D/BluetoothGatt(26771): onClientRegistered() - status=0 clientIf=5
03-06 13:00:42.004: D/BluetoothGatt(26771): onClientConnectionState() - status=133 clientIf=5 device='device id comes here'

解决方案

Certain devices require Bluetooth LE interactions to be run on the UI thread. So I would recommend trying something like this:

// Create handler for main thread where mContext is application context
mHandler = new Handler(mContext.getMainLooper());
...
// Connect to BLE device from mHandler
mHandler.post(new Runnable() {
@Override
public void run() {
    mBTGatt = mBTDevice.connectGatt(mContext, false, mGattCallback);
}
});

Of course you could use Activity.runOnUiThread as well. Source: http://stackoverflow.com/a/23478737
