iOS藍牙中央管理器

Question

我正在試用iPhone上的iOS藍牙中央管理器。

- (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"); 
    } 
} 

它總是去硬件是不支持的選擇。

此外，我可以通過藍牙在Android手機之間發送圖片，但是當我試圖發送到我的iPhone時，它被拒絕。 iOS藍牙是封閉的嗎？它不適用於其他藍牙設備？

聽起來像你的iOS設備不支持藍牙低功耗。

唯一受支持的iOS設備是iPhone 4S，iPhone 5，iPhone 5c，iPhone 5s，iPad 3rd Gen，iPad 4th Gen，iPad air，iPad mini和iPod Touch第五代（和更新設備）。
