iOS 蓝牙中央管理器

Question

我正在 iPhone 上试用 iOS 蓝牙中央管理器。

- (void)centralManagerDidUpdateState:(CBCentralManager *)central
{
    // Determine the state of the peripheral
    if ([central state] == CBCentralManagerStatePoweredOff) {
        NSLog(@"CoreBluetooth BLE hardware is powered off");
    }
    else if ([central state] == CBCentralManagerStatePoweredOn) {
        NSLog(@"CoreBluetooth BLE hardware is powered on and ready");
    }
    else if ([central state] == CBCentralManagerStateUnauthorized) {
        NSLog(@"CoreBluetooth BLE state is unauthorized");
    }
    else if ([central state] == CBCentralManagerStateUnknown) {
        NSLog(@"CoreBluetooth BLE state is unknown");
    }
    else if ([central state] == CBCentralManagerStateUnsupported) {
        NSLog(@"CoreBluetooth BLE hardware is unsupported on this platform");
    }
}

总是出现硬件不支持的选择。

此外，我可以通过蓝牙在 Android 手机之间发送图片，但是当我尝试发送到 iPhone 时，它​​被拒绝了。 iOS蓝牙是封闭式的吗？它无法与其他蓝牙设备配合使用吗？

听起来您的 iOS 设备不支持低功耗蓝牙。

唯一支持的 iOS 设备是 iPhone 4S、iPhone 5、iPhone 5c、iPhone 5s、iPad 第 3 代、iPad 第 4 代、iPad Air、iPad mini 和 iPod Touch 第 5 代(以及更新的设备)。
