    * conditions for timers 
    * Need to know how long before reset 
    * https://github.com/adafruit/Adafruit_SleepyDog/blob/master/examples/BasicUsage/BasicUsage.ino 


* implement the different packet that will be sent for recovery
    * Include metadata in our packet (flight mode)

* When initializing radio module we need to set the channel with the serial number  

* need two separate serial numbers from two separate addresses, one for channel and one for downlink time 

* llcc68 radio module instead
