Question

我希望您做得很好，遇到一个问题，当我搜索蓝牙设备时，我会获得一些带有名称的设备，但大多数设备不提供其名称，而那些设备在以下位置提供了名称Iphone的蓝牙，我尝试了一些解决方法

1-首先连接到设备，然后在委托中获得名称（peripheralDidUpdateName），在这种情况下，我得到了来自少数设备的响应，而其他设备则处于连接状态 2-我试图搜索一些延迟的设备，以便我可以找到名称，但仍然遇到相同的问题

extension LandingPage : CBCentralManagerDelegate , CBPeripheralManagerDelegate {
    func centralManagerDidUpdateState(_ central: CBCentralManager) {

        switch (central.state) {
        case .poweredOff :
            print("bluetooth is off ")
            self.mainPeripheral.removeAll()
        case .poweredOn :
            print("bluetooth is on ")
            manager?.scanForPeripherals(withServices: nil, options: nil)
         }
     }
return

实际结果：

<CBPeripheral: 0x282d090e0, identifier = D94CC0E6-0340-8406-4688-C38D593F3201, name = (null), state = disconnected>
<CBPeripheral: 0x282d0d040, identifier = 04F5A632-3FBE-47A6-C6A6-2DDF9975184C, name = (null), state = disconnected>
<CBPeripheral: 0x282d0d040, identifier = CE0FD194-7E7D-4004-C50B-049C2958F495, name = (null), state = disconnected>
<CBPeripheral: 0x282d0d040, identifier = E780781F-7D6B-8052-9743-ECFEB5C534C8, name = (null), state = disconnected>

预期：

<CBPeripheral: 0x282d0c0a0, identifier = 803732A6-31F9-A740-EC6A-8C9E3CDE8F71, name = Lefun, state = disconnected>
<CBPeripheral: 0x282d0d040, identifier = 6C19BC9F-1891-82DE-51D6-0C0E371F2E03, name = LH719, state = disconnected>
