Question

我在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");
    }
}

它始终是硬件不受支持的选择。

此外，我能够通过蓝牙在Android手机之间发送图片，但是当我尝试发送到我的iPhone时，它被拒绝了。 iOS蓝牙是封闭的吗？它不适用于其他蓝牙设备？

Answer 1

听起来你的iOS设备不支持低功耗蓝牙。

唯一受支持的iOS设备是iPhone 4S，iPhone 5，iPhone 5c，iPhone 5s，iPad 3rd Gen，iPad 4th Gen，iPad air，iPad mini和iPod Touch 5th Gen（以及更新的设备）。
