Hey folks, wanted to chime in and offer my two cents (Hologram has not released any official documentation on this subject). From my preliminary research I’ve found TCP offers an overhead savings over UDP if you publish data in 50 minute or greater intervals. We’ve found it typical for cellular IoT solutions to broadcast less frequently.
If you need to report in intervals less than ~30 minutes then you are getting into territory where UDP would offer savings. But to that developer I would probably see if they could log data on the edge and transmit less frequently or move to a wifi solution as that might be a better fit.
I’m curious to hear what you think. If more people ask for UDP then we can add it to our roadmap.
