SimpleMLLPClient timeout error

[jorge-zapata-medstone]

Description:

Im having problems with the SimpleMLLPClient from the nhapiTools library i know this is not the same library but i was wondering if anyone has had any issues where the connection would timeout?.

Code:

try
{
    // Create connection object
    var connection = new SimpleMLLPClient(CONNECTION_URL, PORT_NUMBER, encoding);

    // Send the previously created HL7 message over the connection established
    IMessage responseMessage = connection.SendHL7Message(hl7Message);

    // Display the message response received from the remote party
    var responseString = pipeParser.Encode(responseMessage);

    return responseMessage;
}
catch (Exception e)
{
    throw new Exception($"Error occured while sending HL7 message {e.Message}");
}

In the example above if the CONNECTION_URL or the PORT_NUMBER is not available i never reach the catch portion of the code which leaves the program running indefinitely.

Does anyone know how to catch this error or avoid it?

EDIT:

I just found out that i has a timeout of like 1-2 minutes is there a way i can reduce the timeout to idk 20-30 seconds?

@dib0 is this something you can help with?

Hi,

TCP connections can timeout. Most systems should keep the TCP connection for HL7 messages open, so a timeout shouldn't happen too often. If it does, please check with the vendor or specs of the other system.

You can decrease the timeout when calling the constructor. The default setting is 30 seconds (check below).
public SimpleMLLPClient(string hostname, int port, int receiveTimeout = 30000)

You can set it to whatever timeout you want (it is in milliseconds). For example (10 seconds):
var client = new SimpleMLLPClient(192.168.0.5, 1000, 10000)

On a timeout the method should send a TimeoutException, do your receive those?

Hope this helps!
