蓝牙断开连接时间太长

问题描述

我可以连接到我的蓝牙设备，当我想断开连接时，大约需要 30 秒才能断开连接，并在几秒钟内断开连接并在后台自动重新连接到设备我不希望这种情况发生，怎么办我从字面上断开它？我处理服务和设备并将其拉为空，但这不起作用

这是断开连接方法：

public bool disConnect()
    {
        try
        {
            IsScannerActiwe = false;
            Buttonpressed = false;
            IsConnected = false;
            
            if (currentSelectedGattCharacteristic != null && currentSelectedService != null)
            {
                currentSelectedGattCharacteristic.Service?.dispose();
                currentSelectedService?.dispose();
                currentSelectedGattCharacteristic = null;
                currentSelectedService = null;
                if (bluetoothLeDevice != null)
                {
                    bluetoothLeDevice.dispose();
                    bluetoothLeDevice = null;
                    return true;
                }
            }   
        }
        catch (System.Exception ex)
        {
            Trace.WriteLine("Exception Handled -> disConnect: " + ex);
        }
        return false;
    }

我处理设备和服务并将其拉为空，该函数返回true但它不会断开连接并且它为空几秒钟并且服务继续在后台自动运行

我还尝试了另一个断开连接的功能

public async Task<bool> ClearBluetoothLEDevice()
    {
        if (IsConnected)
        {
            IsScannerActiwe = false;
            Buttonpressed = false;
            IsConnected = false;
            // Need to clear the CCCD from the remote device so we stop receiving notifications
            var result = await currentSelectedGattCharacteristic.WriteClientCharacteristicConfigurationDescriptorAsync(GattClientCharacteristicConfigurationDescriptorValue.None);
            if (result != GattCommunicationStatus.Success)
            {
                return false;
            }
            else
            {
                if (currentSelectedGattCharacteristic != null)
                {
                    currentSelectedGattCharacteristic.ValueChanged -= CurrentSelectedGattCharacteristic_ValueChanged;
                    IsConnected = false;
                    currentSelectedService.dispose();
                    currentSelectedGattCharacteristic.Service.dispose();

                    currentSelectedService?.dispose(); //added code
                    currentSelectedService = null; //added code
                    bluetoothLeDevice?.dispose();
                    bluetoothLeDevice = null;
                    currentSelectedGattCharacteristic = null;
                    return true;
                }
                
            }
        }
        return false;
        
    }

我确实无法与设备断开连接
