Wrap a synchronous function in Asynchronous call c#

问题

I have a server, which must poll an equipment through the network, to obtain information, process it and then send it to the users. The equipment survey becomes a synchronous blocking function.

My question is:

How to create an own asynchronous function version to perform this function using Task or another asynchronous pattern???

Consider the following code to get information from equipment:

IEnumerable<Logs> GetDataFromEquipment(string ipAddress)
        {
            Equipment equipment = new Equipment();
            //Open communication with equipment. Blocking code.
            int handler = equipment.OpenCommunication(ipAddress);
            //get data from equipment. Blocking code.
            IEnumerable<Logs> logs = equipment.GetLogs(handler);
            //close communication with equipment
            equipment.CloseCommunication(handler);

            return logs;
        }

Thanks

You can use async/await

 public async Task<IEnumerable<Logs>> GetDataFromEquipment(string ipAddress)
    {

        var task = Task.Run(() =>
        {
            Equipment equipment = new Equipment();
            //Open communication with equipment. Blocking code.
            int handler = equipment.OpenCommunication(ipAddress);
            //get data from equipment. Blocking code.
            IEnumerable<Logs> logs = equipment.GetLogs(handler);
            //close communication with equipment
            equipment.CloseCommunication(handler);

            return logs;
        });

        return await task;
    }
