ios- cbcentralManager状态未知和CoreBluetooth [警告] <CBConcreteCentralManager>未通电

我正在研究CoreBluetooth框架。我跑了著名temperatureSensor应用程序，但是当我在模拟器上运行它，我得到以下警告：ios- cbcentralManager状态未知和CoreBluetooth [警告] <CBConcreteCentralManager>未通电

CoreBluetooth[WARNING] <CBConcreteCentralManager: 0x713b550> is not powered on

我查的CBCentralManager状态是Unknown。以下是代码：

(void) startScanningForUUIDString:(NSString *)uuidString { 
    centralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil]; 

    if ([centralManager state] == CBCentralManagerStatePoweredOff) NSLog(@"CBCentralManagerStatePoweredOff"); 
    if ([centralManager state] == CBCentralManagerStatePoweredOn) NSLog(@"CBCentralManagerStatePoweredOn"); 
    if ([centralManager state] == CBCentralManagerStateResetting) NSLog(@"CBCentralManagerStateResetting"); 
    if ([centralManager state] == CBCentralManagerStateUnauthorized) NSLog(@"CBCentralManagerStateUnauthorized"); 
    if ([centralManager state] == CBCentralManagerStateUnknown) NSLog(@"CBCentralManagerStateUnknown"); 
    if ([centralManager state] == CBCentralManagerStateUnsupported) NSLog(@"CBCentralManagerStateUnsupported"); 
    NSArray *uuidArray = [NSArray arrayWithObjects:[CBUUID UUIDWithString:uuidString], nil]; 

    NSLog(@"%@", uuidArray); 
    NSDictionary *options = [NSDictionary dictionaryWithObject:[NSNumber numberWithBool:NO] forKey:CBCentralManagerScanOptionAllowDuplicatesKey]; 
    [centralManager scanForPeripheralsWithServices:uuidArray options:options]; 
}

我该如何解决？

似乎蓝牙设备未连接或未检测到。即使您的机器可能具备BTLE功能，您也需要连接外部USB BLE适配器才能够与模拟器一起使用。来自Apple的这application note可能是有利的

umm所以如果它的温度传感器应用程序，那么蓝牙设备必须是一个温度传感器启用BT正确吗？ – z22

是的，这是正确的 –

哦好吧，非常感谢！ – z22
