iOS 和 Android 蓝牙低功耗连接之间的区别

Question

我有一个BLE周边设备。我无法使用 BluetoothLeGatt 示例 android 应用程序连接到它，Android 市场中没有其他 BLE 应用程序。但是 iOS BLE 应用程序可以连接到它。这是 BluetoothLeGatt 连接日志：

我应该如何连接到这个设备？ Android 和 iOS BLE 连接到 BLE 外围设备有什么区别？

更新： 我的 Android 台设备：

HTC One M7。 Android版本：5.0.2

LG Nexus 5X。 Android 版本：6.0.1

Answer 1

07-21 21:07:50.934 27402-27402/bluetoothlegatt D/BluetoothLeService: Trying to create a new connection.
07-21 21:07:56.060 27402-27421/bluetoothlegatt D/BluetoothGatt: onClientConnectionState() - status=133 clientIf=5 device=xx:xx:xx:xx:xx:xx
07-21 21:07:56.060 27402-27421/bluetoothlegatt D/BluetoothDevice: mAddress: xx:xx:xx:xx:xx:xx
07-21 21:07:56.060 27402-27421/bluetoothlegatt I/BluetoothLeService: Disconnected from GATT server.

发送连接请求后，到onClientConnectionState，大约有5秒的寻呼时间，估计是寻呼超时了。

查询很少： 1)这个问题是否也发生在其他 Android phone 或只有你的测试 phone？ 2)您设备的广告间隔是多少？

奇怪，搜索到设备却无法连接；或者它应该是您的 phone 和您的设备之间的 RF 问题。

Answer 2

看来我找到了答案。我们使用 CC2564 德州仪器芯片。对于使用 BluetoothLeGatt Android 与此芯片的 BLE 连接，示例应用程序需要替换此命令：

mBluetoothGatt = device.connectGatt(this, false, mGattCallback);

此命令：

mBluetoothGatt = device.connectGatt(this, false, mGattCallback,BluetoothDevice.TRANSPORT_LE);
