> 832:[ts=6499968ssb, mod=4 level=0] Disconnection Complete: status=0 handle=1 reason=8
> Appears to be related to the flash erase

> Flash erase is blocking and takes a while, so traditionally on nordic softdevic schedule to work outside of radio events as much as possible.  newtmgr isnt and probably shouldn't be coupled down to the radio abstraction.
> Nordic forum also talks about altering intervals and latencies, 
> https://devzone.nordicsemi.com/question/24290/slow-flash-erase-performance-with-sd_flash_page_erase/?answer=24361#post-id-24361
> but discussion on the list also found that a lacking solution
> One possible solution discussed solution was to separate erase from upload commands
