    Good morning,

    We recently upgraded our gateway from 3.3.9 to 3.3.24 and at first glance everything appeared fine. However, we noticed that uplinks were split between two possible MQTT topics.

    Some packets were at lora/<dev id>/up and others at lora/<gateway id>/<dev id>/ up.This behaviour was not limited to a specific node and there did not appear to be a pattern to when a node’s packet will be published under lora/<dev id> versus lora/<gateway id>/<dev id>.

    I downgraded the firmware back to 3.3.9 and this problem no longer occurred. We did not make any changes to mosquitto’s config with the exception of modifying the bind address.

    Has anyone else experienced this?

    lora-network-server v2.0.19 in mLinux v3.3.24

    up messages will be published to the following topics
    lora/<DEV-EUI>/up
    lora/<APP-EUI>/<DEV-EUI>/up
    lora/<APP-EUI>/<DEV-EUI>/<PORT>/up

    The same message should appear on all topics.
