swift – 观看操作系统2：配对的iPhone和Apple Watch之间是否有可能获得蓝牙信号连接强度？

标题是不言自明的.我尝试过CoreBluetooth,但我没有看到Apple Watch是一个连接的外设.

解决方法

您需要检查 RSSI信号电平.

您可以使用：

- (void)centralManager:(CBCentralManager *)central diddiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI {
    NSLog(@"Did discover peripheral. peripheral: %@ RSSi: %@,UUID: %@ advertisementData: %@ ",peripheral,RSSI,peripheral.UUID,advertisementData);
    //Do something when a peripheral is discovered.

    RSSiLabel.text = [RSSI stringValue];

    [manager retrieveperipherals:[NSArray arrayWithObject:(id)peripheral.UUID]];}
