Has anyone tried the deep sleep mode?
I am wondering if the power for the RTC in deep sleep mode needs to be applied through the pin on the chip labelled VDD_RTC? Or is that an output for a different RTC than the internal clock?
On a related note, Light sleep "disables the crystal", which to my mind would disable the RTC (or at least make it not reliable).
FYI, testing different boards over long periods, the clock accuracy (Action Mode) has been +/- 5 seconds per day with random variations over the temperature range 10-20C. This was not a complete test, merely observations from the devices I am logging here.
