需要在Android ICS上使用Motorola GATT Profile API的蓝牙低功耗示例

时间：2012-11-01 20:40:11

标签： android motorola bluetooth-lowenergy

截至今天，摩托罗拉开发者门户网站正在将问题重定向到Stack Overflow和Google Android论坛，所以希望摩托罗拉的某位人员能够倾听。

我正在尝试在ICS设备（我的案例中为Atrix HD）上提供一个简单的应用程序，可以查询和编写GATT配置文件（不仅仅是心率监测器）。

对于ICS，http://www.motorola.com/sites/motodev/library/bluetooth_gatt_apis.html处的说明/示例充其量不完整。例如，MOT_BTLE_Stubs.jar不包含在ICS下载中。相反，我们有BluetoothGatt.jar和BluetoothGattService.jar。但是这些库没有教程中提到的BluetoothGatt.connectGatt（...）。

ICS附加组件包含一个示例，它引导我生成ACTION_GATT意图，但是当我获得以下NULL返回时失败：

String [] ObjectPathArray =（String []）intent.getStringArrayExtra（BluetoothDevice.EXTRA_GATT）;

一个精心编写的ICS示例将为摩托罗拉和小型但不断发展的Android BLE开发者社区提供出色的服务。

谢谢！

我偶然发现了同样的问题。

我将Razr XT910更新为Android ICS（4.0.4），我使用的是Motorola Handset SDK Addon“Motorola_ICS_R2”。

我现在正在谈论SDK Addon示例“Motorola_BLE_profile_sample”，我将其作为配置文件模板与TI运行SimplePeripheral示例的TI CC2540开发套件的Keyfob进行通信。

当您创建个人资料服务时，请确保调用BluetoothGattService（...）包含您要连接的设备的有效GATT Primary Service Declaration UUID。这将解决您的空ObjectPathArray的问题。

例如，我的Keyfob使用UUID 0x180A实现设备信息服务，您可以在BLE CC2540 Dev Kit用户指南中找到Keyfob的这些信息（http://www.ti.com/lit/ug/ swru270b / swru270b.pdf）在图20中的第14页。您是否看到句柄0x01,0x0C，0x0F的类型0x2800，这些都是主要服务。您可以找到GATT配置文件属性类型here。现在您从

更改配置文件模板（Motorola_BLE_profile_sample） 
    public static final ParcelUuid HRM = ParcelUuid
        .fromString("0000180D-0000-1000-8000-00805f9b34fb");

为：

    public static final ParcelUuid HRM = ParcelUuid
        .fromString("0000180A-0000-1000-8000-00805f9b34fb");

运行应用程序后，LogCat看起来像：

完全同意您关于Motorolas文档，示例和开发人员支持的错误程度。

我找到了这个：http://www.tekritisoftware.com/how-to-implement-ble-in-android 这可能会有所帮助，但我还在等待我的btle设备，所以还没有尝试过。
