It would be great if this SDK supports micropython,
micropython uses async keyword.
See also https://github.com/micropython/micropython
MicroPython implements the entire Python 3.4 syntax (including exceptions, with, yield from, etc., and additionally async/await keywords from Python 3.5)
Programs can be written to be Cpython3/micropython compatible,
take this for example https://github.com/pfalcon/picotui
