  • Every time when the Bacnet device sends a Simple ACK as answer, bacnet4j throws a "Timeout-Exception" in ServiceFutureImpl
    We use the neweset branch bacnet4j 3.2.4 for our software...

    two examples with Simple ACK:

      1. Receiving Ack for AcknowledgeAlarm using AcknowledgeAlarmRequest:

    a source:
    AcknowledgeAlarmRequest req = new AcknowledgeAlarmRequest(
    new UnsignedInteger(
    localDevice.getConfiguration().getId().getInstanceNumber()),
    oId, EventState.lifeSafetyAlarm, timeStamp, new CharacterString("Cobra"), now);

    b exception:
    com.serotonin.bacnet4j.exception.BACnetException: Timeout waiting for response.
    at com.serotonin.bacnet4j.transport.ServiceFutureImpl.get(ServiceFutureImpl.java:71)

    c wireshark:

    0_1469535439741_2.jpg
    Simple ACK:
    0_1469535477399_3.jpg

      1. addListElement

    a source:
    RequestUtils.addListElement(localDevice, remoteDevice,
    new ObjectIdentifier(ObjectType.notificationClass,
    ncNumber),
    PropertyIdentifier.recipientList,
    new SequenceOf<Destination>(specs));

    b exception:
    com.serotonin.bacnet4j.exception.BACnetException: Timeout waiting for response.
    at com.serotonin.bacnet4j.transport.ServiceFutureImpl.get(ServiceFutureImpl.java:71)
    at com.serotonin.bacnet4j.util.RequestUtils.addListElement(RequestUtils.java:526)

    c wireshark:
