Further Power-Saving Improvements

Open darksidelemm opened this issue 4 years ago • 1 comments

Just leaving myself some notes:

  • Gap between transmissions, send 'pips' every X seconds when in this gap so listeners know there's something there.
  • Look at more GPS power-saving settings.
  • Power down radio more between pips?

A lot of this has now been implemented:

  • uBlox GPS power-save mode is working reliably.
  • A 'deep sleep' mode that powers down the GPS has been implemented.

There's still possibly some improvements to be made in putting the STM32 into a lower-power sleep state. At the moment it's essentially busy-waiting, running at full speed. There may also be other devices on the board drawing current which we can disable in software.
