  Hi Gordon,

  Thank you so much for your answer.
  I understand that getting to the very low consumption modes require extra care, even on how the rest of the components behave, and also understand the choice of not having implemented it.

  I will have a look at the link you sent about the Bangle.js and see if I can try to implement it myself.

  Thanks again,

  Thomas

  Hi,

  I have checked into the power consumption of the Espruino and discovered that it consumes around 5 µA at its lowest.
  This is not the lowest power consumption mode given by the MDBT42Q datasheet which shows that is can go even below 1 µA in some cases.
  On the nrf5 SDK this mode corresponds to the SD_POWER_SYSTEM_OFF which almost turns off the device and only wakes it on GPIO input or reset.
  Is there a way to activate this mode using your programming interface ? Or is there a way to maybe add this function in a custom firmware?
  What would be the bast starting point to implement this ?

  Thanks in advance for your help !
  Kind regards,

  Thomas
