 for taiwan region:
 bin/run.sh --set region 8
 
-change defaults to 2 min 
+time only mode
+./bin/run.sh --set gps_operation 3
+
+do new power measurements
 
 fix has_gps based on new logic
 
+don't send locations if the user has forbidden that (lie to phone so phone won't either)
+
 have loop methods return allowable sleep time (from their perspective)
 increase main cpu sleep time
 
 add set router mode in python tool - it will also set GPS to stationary
+make sure location still gets set once per boot and stays marked as valid on the gui 
+send position updates super rarely
 (which will shrink DARK and NB period to zero and
  make light_sleep very long)
 
 warn people about crummy gps antennas - add to faq
