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

Question

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个人正在倾听。

我试图在ICS设备（我的情况下是Atrix HD）上提出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上的说明/示例充其量是不完整的。 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）;

一个写得很好的ICS示例将为摩托罗拉和小而成长的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。

我有一个更新到Android ICS（4.0.4）的Razr XT910，我正在使用摩托罗拉手机SDK插件“ Motorola_ICS_R2 ”。

我现在正在讨论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 Dev Kit的Keyfob进行通信。

创建配置文件服务时，请确保调用BluetoothGattService（...）包含您要连接的设备实施的有效GATT主服务声明UUID 。 这将解决您的空ObjectPathArray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 。在图20中的第14页上.pdf）你看到句柄0x01,0x0C，0x0F的类型0x2800，这些都是主要服务。 您可以在此处找到GATT配置文件属性类型。 现在您从中更改配置文件模板（Motorola_BLE_profile_sample）

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

至：

    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糟糕程度。

我确实找到了这个： 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。
