    Hi,

    While going through the link (http://www.multitech.net/developer/software/lora/lora-network-server/mqtt-messages/) it occurred to me that conduit keeps the queue of messages from different end device. I have a few queries about that:
    1. What are the size of those queues managed by Conduit
    2. Is there any way I could configure queue parameters (size and other values) in mLinux Conduit? If it is possible to do so, where is the configuration file available for that?

    thanks,

    See nodeQueueSize in advanced configuration. Some have found it better to set the network server queue to one rather than manage two queues. Only the size is configurable.

    Thanks Jason,

    What is the default value for this nodeQueueSize?
    Also is there any way to print all the advanced Lora configurations using either lora-query or some other utility?

    thanks,

    There is a command port

    The ‘nc’ utility is working fine, and I could set/get the queue size.
    But is there any way by which we could query and find the status of the queue, I mean how many slots are still open?
    Also I saw a downstream MQTT topic for clearing the queue-
    lora/<DEV-EUI>/clear
    I used it as below:
    mosquitto_pub -t lora/00:11:22:33:44:55:66:77/clear
    and I got an error “Error: Both topic and message must be supplied.”

    Can you please tell what I am missing here? Is there any other way to use this topic?

    thanks,
