CoreBluetooth может принимать команды только в состоянии подключения

[CoreBluetooth] API MISUSE: <CBPeripheral: 0x281310820, identifier = 75450BB1-97A7-5648-38FD-B27572F19EDD, name = ESP32 test, state = disconnected> can only accept commands while in the connected state

Это ошибка, которую CoreBluetooth выдает, когда я пытаюсь

peripheral.discoverServices([CBUUID(string: "4fafc201-1fb5-459e-8fcc-c5c9c331914b")])

Кто-нибудь знает, что происходит?

Вот делегат didDiscover:

func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
    var peripheralName: String!
    if let name = advertisementData[CBAdvertisementDataLocalNameKey] as? String {
        peripheralName = name
    }
    else {
        peripheralName = "Unknown"
    }
    
    if(advertisementData[CBAdvertisementDataServiceUUIDsKey] != nil) {
        //print(advertisementData)
        let Ids: [CBUUID] = advertisementData[CBAdvertisementDataServiceUUIDsKey] as! [CBUUID]
        if(Ids.count == 1) {
            print(Ids[0])
            let newPeripheral = Peripheral(id: peripherals.count, name: peripheralName, rssi: RSSI.intValue)
            //print(newPeripheral)
            /*
            if let services = peripheral.services {
                for service in services {
                    print("servizio")
                    //peripheral.discoverCharacteristics([CBUUID(string: "4fafc201-1fb5-459e-8fcc-c5c9c331914b")], for: service)
                }
            }*/
            if(accepted_services.contains(Ids[0].uuidString)) {
                print(newPeripheral)
                peripherals.append(newPeripheral)
                peripheral.delegate = self
                peripheral.discoverServices([CBUUID(string: "4fafc201-1fb5-459e-8fcc-c5c9c331914b")])
                //peripheral.discoverCharacteristics([CBUUID(string: "beb5483e-36e1-4688-b7f5-ea07361b26a8")], for: <#CBService#>)
            }
        }
    }
}

EDIT: я попытался сначала подключиться к периферийному устройству, НО есть еще одна ошибка:

[CoreBluetooth] API MISUSE: Cancelling connection for unused peripheral <CBPeripheral: 0x2829e01e0, identifier = 75450BB1-97A7-5648-38FD-B27572F19EDD, name = ESP32 test, state = connecting>, Did you forget to keep a reference to it?

это реальный код:

    func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String:Any], rssi RSSI: NSNumber) {
    print("scoperto peripheral")
    myCentral.connect(peripheral, options: nil)
}

Что это означает?
