[straga]

Run uasyncio in the thread.
ESP-IDF 4.4.
micropython: master

IF run not in the _thread work like before. Before a couple of months ago work right in Thread too.

    # AsyncIO in thread
    loop = asyncio.get_event_loop()
    _ = _thread.stack_size(8 * 1024)
    _thread.start_new_thread(loop.run_forever, ())
