pytrack and lowpower

[Morten Guldager]

I'm using a pytrack(v1) + fipy stack

I'm trying to get into low power idle. So basically i hit:

py.setup_sleep(300)
py.go_to_sleep(gps=True)

But unfortunately this kills both NVRAM and RTC on the ESP32

And if I just go with the regular micropython

machine.deepsleep(300*1000)

the pytrack board hovers around 25mA which is very far from low power in my book.

Suggestions?

@Morten-Guldager Power consumption in deep sleep is a recurring topic and there are quite a few possible causes:

• The FiPy does not actually go to deep sleep
• The LTE modem is still active
• The GPS is still active at full power

See https://forum.pycom.io/topic/7020/fipy-pytrack-2-0-deepsleep-power-consumption/6 and https://forum.pycom.io/topic/6839/fipy-deepsleep-methods/20?page=1 for a few hints.

Make sure you have the right versions of firmware of the FiPy and PyTrack and modem.
