Key register usage
Can you please clarify how long the "key register" keeps its value after I set it using
Does it keep its value until another
mbl_mw_debug_set_key_register call, or until the sensor reboots?
Or does any other firmware or Mbient SDK logic change its value?
I'd like to use it to determine if the sensor has rebooted or run out of battery since the last time my app was connected to it.
