Could someone clarify the “Last Activity” indication on the device dashboard. What is that based on specifically? It does not appear to be related to last tcp data activity from the device. I see it update often when the device first connects, but not always. Is there anything I can do on the modem side to update this value in a predictable way?
At the moment I am disappointed with the high relative bandwidth required with the TCP api just to implement a heartbeat. Wish there were better way. Yes, I could leverage an mqtt server but that is yet another layer of complexity just to achieve a simple goal of regular heartbeat indication.
Thanks for any feedback.
