  Hello,

  Is it possible to write to unused persistent storage?
  According to http://www.espruino.com/STM32F1Flash the Puck doesn't use address 468992 to 479232 (10kB)

  but STM32F1Flash.js or poke calls are not able to write to these addresses.
  Do I miss something?

  Hi Gordon,

  NRF.sleep() totally turns off bluetooth, which you probably don't want :)

  This is exactly what i've tried to do to save some battery capacity.
  Unfortunately the Puck doesn't show up again after NFR.wake()
  Do I have to do anything else after enabling bluetooth again?
  Do I have to setup advertisements using NRF.setServices / NRF.setAdvertising?

  Edit:

  NRF.setServices({},{uart:true});
  

  just after NRF.wake() fixed it :)
