如何在OS X上检查硬件BLE支持？

Question

我已经阅读here，2011年中期的Apple电脑应支持BLE（蓝牙低功耗）。有没有办法（可能使用命令行）来检查设备和操作系统是否支持BLE？

Answer 1

在Mac OS X终端应用中，您可以输入以下内容：

system_profiler -detailLevel full SPBluetoothDataType | grep "LMP Version"

如果此命令输出＆gt; = '0x6'，则支持蓝牙4.0，因此也支持BLE。

Answer 2

1）通过AppStore安装适用于Mac OS的LightBlue。

2）如果它像所附的截图一样抱怨，你的硬件不支持蓝牙LE，如果它没有抱怨“这一切都很好”。

显然，iOS和OSX的CBCentralManager api是相同或非常相似的（不确定是否可以预期，因为我刚开始使用iOS和OS X），从某种意义上说，可以运行代码：< / p>

switch ([_manager state])
{
    case CBCentralManagerStateUnsupported:
        state = @"This device does not support Bluetooth Low Energy.";
        break;
    case CBCentralManagerStateUnauthorized:
        state = @"This app is not authorized to use Bluetooth Low Energy.";
        break;
    case CBCentralManagerStatePoweredOff:
        state = @"Bluetooth on this device is currently powered off.";
        break;
    case CBCentralManagerStateResetting:
        state = @"The BLE Manager is resetting; a state update is pending.";
        break;
    case CBCentralManagerStatePoweredOn:
        state = @"Bluetooth LE is turned on and ready for communication.";
        break;
    case CBCentralManagerStateUnknown:
        state = @"The state of the BLE Manager is unknown.";
        break;
    default:
        state = @"The state of the BLE Manager is unknown.";

}

在OS X中提供等效的iOS Q&A（信用额去Bob那里），并了解设备是否支持ble。

点击左上角的苹果图标，然后点击关于本机 - ＆gt;左侧的系统报告... 点击硬件 - ＆gt;的蓝牙下， 您将在硬件，功能和设置下找到支持蓝牙低功耗。
