【问题描述】：
我想开发一个在不知道 uuid 的情况下检测大量信标设备的应用程序。但是我找不到这样做的方法。我必须在代码中定义 uuid。
我开发了一个适用于已知设备的 POC。
我的视图控制器代码：
-(void)setUpview
{
// Regardless of whether the device is a transmitter or receiver, we need a beacon region.
NSUUID * uid = [[NSUUID alloc] initWithUUIDString:@"78CDC73D-D678-4B35-A88A-C2E09E5B963F"];//[UIDevice currentDevice].identifierForVendor;
treasureId = @"com.eden.treasure";
self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uid identifier:treasureId];
// Location manager.
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
if([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
[self.locationManager requestAlwaysAuthorization];
}
[self.locationManager startMonitoringForRegion:self.beaconRegion];
[self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
[self locationManager:self.locationManager didStartMonitoringForRegion:self.beaconRegion];
[self.beaconRegion setNotifyEntryStateOnDisplay:YES];
[self.beaconRegion setNotifyOnEntry:YES];
[self.beaconRegion setNotifyOnExit:YES];
// self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self queue:nil];
if ([UIDevice currentDevice].userInterfaceIdiom==UIUserInterfaceIdiomPad || [[[UIDevice currentDevice] model] isEqualToString:@"iPad Simulator"])
{
[self configureTransmitter];
}
else {
[self configureReceiver];
}
}
-(void)configureTransmitter
{
// The received signal strength indicator (RSSI) value (measured in decibels) for the device. This value represents the measured strength of the beacon from one meter away and is used during ranging. Specify nil to use the default value for the device.
NSNumber * power = [NSNumber numberWithInt:-63];
self.peripheralData = [self.beaconRegion peripheralDataWithMeasuredPower:power];
// Get the global dispatch queue.
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
// Create a peripheral manager.
self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self queue:queue];
}
-(void)configureReceiver {
// Location manager.
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
[self.locationManager requestAlwaysAuthorization];
[self.locationManager startMonitoringForRegion:self.beaconRegion];
[self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
}
#pragma mark - CBPeripheralManagerDelegate methods
-(void)peripheralManagerDidUpdateState:(CBPeripheralManager *)peripheral
{
// The peripheral is now active, this means the bluetooth adapter is all good so we can start advertising.
if (peripheral.state == CBPeripheralManagerStatePoweredOn)
{
[self.peripheralManager startAdvertising:self.peripheralData];
}
else if (peripheral.state == CBPeripheralManagerStatePoweredOff)
{
NSLog(@"Powered Off");
[self.peripheralManager stopAdvertising];
}
}
-(void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region
{
if(state == CLRegionStateInside)
{
NSLog(@"%@",[NSString stringWithFormat:@"You are inside region %@", region.identifier]);
}
else if(state == CLRegionStateOutside)
{
NSLog(@"%@",[NSString stringWithFormat:@"You are outside region %@", region.identifier]);
}
else
{
return;
}
}
-(void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region
{
if ([beacons count] == 0)
return;
NSString * message;
UIColor * bgColor;
CLBeacon * beacon = [beacons firstObject];
switch (beacon.proximity) {
case CLProximityUnknown:
message = [NSString stringWithFormat:@"ProximityUnknown -- %ld", (long)beacon.proximity];
bgColor = [UIColor blueColor];
break;
case CLProximityFar:
message = [NSString stringWithFormat:@"ProximityFar -- %ld", (long)beacon.proximity];
bgColor = [UIColor colorWithRed:.0f green:.0f blue:230.0f alpha:1.0f];
break;
case CLProximityNear:
message = [NSString stringWithFormat:@"ProximityNear -- %ld", (long)beacon.proximity];
bgColor = [UIColor orangeColor];
break;
case CLProximityImmediate:
default:
message = [NSString stringWithFormat:@"ProximityImmediate -- %ld", (long)beacon.proximity];
bgColor = [UIColor redColor];
break;
}
if (beacon.proximity != self.previousProximity)
{
[lblStatus setText:message];
[self.view setBackgroundColor:bgColor];
self.previousProximity = beacon.proximity;
}
}
那么有什么方法可以在不知道 uuid 的情况下检测 iBeacon 吗？
注意：使用与check This link 广播信号（虚拟信标）相同功能的示例应用程序。
任何帮助将不胜感激。
【问题讨论】：
-
你应该做不到。如果它是真正的 iBeacon（而不是经典 BLE 设备和 iBeacon 之间的混合体）。 iOS 应该自动翻译 BLE 广播消息并让它仅可用于 CLBeacon 的东西。如果它是有时会广播经典 BLE 内容的混合，您可以使用 CBPeripheralManager 找到它，并获取 UUID 以扫描 CLBeacon。主要问题是 iOS 只提供高级 API 而不是低级 API，而对于 Android，它们（可以）解析自己的消息，然后扫描并采取行动响应任何他们想要的。

您需要知道您要查找的 UUID。您无法扫描所有 UUID
