 - base in promise
   - after knock goto rf_key_init for 1min
 
 
 - rm net_id nodeDAta
 
 - sat failed base after user-ack failed.
    - per 5min
       - prev key_init is from prev base init
       - open channel port knock for request key_init
       - base rf encryt to rk_key_init
       - sat ook rf_key_init
       - do secure xnode sat init.

 - example
    15 sats
    3 base
      result
        ~ 5 sat per base
        on sat reboot init can switch base.

 - xnode sat init
    - any base will do.
