* You've pointed me in some interesting directions ryan-summers  thanks a lot.

Is there an embedded rust iot matrix room btw? Or some other group / discussion place? or even a working group?
I think at least some of us in here are in the same boat: doing some (consulting) iot product development.
Would be nice to discuss a few patterns, crates etc from time to time. ...

I think I will also have a few crates to share in the near future. For instance I plan to publish the defmt log storage (to flash) and flter-and-send-them-to-the-server on request thingy.
