I am connecting to the HiveMQ broker with a Sequans GM02S modem with a keepalive timeout of 3600 seconds (1 hour). However, every 60 seconds the device seems to wake up, but it does not exchange any data with the broker.
When looking at the “client” window within the HiveMQ broker, we can confirm that the keepalive timeout is indeed set to 3600. Is there any other broker configuration setttings that we can change in order to prevent the modem from waking up every 60 seconds?
At this stage we believe that it is broker related, as we have tested the connection to the Mosquitto MQTT broker and we do not see the wakeup every 60 seconds. We will most likely be using Hive in our final product though, and thus need to get this figured out and understand it.
I look forward to hearing any advice!
