XIAO nRF52840 Sense sleep problem #14024
-
|
Hi, I have a XIAO nRF52840 Sense and I'm trying to use lightsleep. An RFM95W Lora board is connected to it which is put in sleep mode when not transmitting. To save additional power I tried putting the XIAO into sleep mode. Am I missing something or is lightsleep broken? (Power consumption measured using a Nordic Power Profiler Kit on the battery connectors of the XIAO ) Edit: Fixed typo |

lightsleep and deepsleep are not implemented for the NRF port. The methods exist, but do almost nothing. |

Thanks for mentioning, 2.5 mA is acceptable though so I'll just omit the sleep then. I guess "the other one" you are referring to is the Nordic PPK2: |

lightsleep() just calls __WFE(), deepsleep() just resets the boards.
Edit: But the XIAO board should behave the same as the other one. Maybe update the firmware. lightsleep() and deepsleep() were moved to extmod in Nov 2023.
