While looking at a project evolving STM32 collecting data, compressing the data, sending the data using UDP I wanted to read up on the functions: uzlib only decompresses and there is no documentation on lwip for micropython.
I did find the source for uzlib and lwip, is there a reason not to add compression and the docs for lwip?
Thanks - looking at STM32L073RZ as the host and I don't think I'll need UDP on the host since it will use a LTE device with AT commands.

See https://github.com/micropython/micropython/pull/5613 -- support for compression was proposed recently.

MicroPython doesn't have docs on LWIP because it provides a Python-compatible socket API instead -- see http://docs.micropython.org/en/latest/l ... ocket.html

You're going to have a tough time fitting MicroPython + LWIP into an L073. But does your LTE device implement the IP stack -- why do you need LWIP?
