> Hello,
> We have an issue with the MQTT ActiveMQ.
> This is our situation:
> Our mobile applications are connected to our ActiveMQ MQTT server.
> We use the LWT message to detect the mobile "network lost".
> We noticed that when we got a mobile "network lost", the LWT message is sent 90s after the disconnect.  If the network comes back before 90s, a retained message is sent to alert the server. But we saw that the "network lost" LWT message is STILL sent even if we received the retained message.
> For me, the LWT message "network lost" should be cancelled if we received a new retained message.
