      Topic about light sleep mode, available since firmware 1.19.0.b1 :
      https://forum.pycom.io/topic/3351/new-development-firmware-release-v1-19-0-b1/14
      Documentation :
      machine.sleep([time_ms], resume_wifi_ble)
      machine.pin_sleep_wakeup(pins, mode, enable_pull)

      My "MicroPython Samples". My "MicroPython Firmwares" with many options (double precision, ulab, etc).

        The current consumption on a LoPy4 is about 3.5 mA during light sleep.

          Measured using only software : about 16 ms to wake up from light sleep. Both using wake on pin (interrupt) or timed light sleep.

          Need to confirm with external measurement : i(t) powering LoPy4 by using oscilloscope + shunt resistor.

            Small issue : how to use "machine.pin_sleep_wakeup()" to wake up from light sleep, then disable it (how ?) and use "machine.deepsleep(60000)" so it wakes only after 60s ?
