在 foreground/background 中从其他 BLE 设备扫描的后台广告外围设备

The background advertised peripheral to be scanned from other BLE devices either in foreground/background

我正在与 iOS 的 BLE 合作，我可以在其中同时建立外围广告和扫描。

我有 2 台设备，它们会同时扫描广告，当设备处于前台时它工作正常。

现在的问题是：设备处于后台，这意味着广告不起作用（无法显示本地名称和 UUID，因为它会按照 Apple 进行屏蔽）因为根据 Apple Docs: advertisement key are placed in a special “overflow” area; they can be discovered only by an iOS device that is explicitly scanning for them.

现在我的问题是如何扫描这个溢出区域？

另请注意，当设备在后台播放广告时，我也不会在下面的代表中收到回电： - (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary<NSString *, id> *)advertisementData RSSI:(NSNumber *)RSSI;

任何可能的方法我都可以做这个方法，这真的很有帮助。

上述情况的解决方案如@Paulw11 所述。我们只需要扫描特定的外设 ID。感谢 Paulw11
