EEPROM block in CyFi Protocol

Question: What is the need of EEPROM block in CyFi protocol?

 

Answer:

 This parameter defines the Flash block number used to store network parameters. Note that a Node device uses one Flash block and a Hub device can use several blocks (each available Device Id needs 8 bytes, so the number of blocks varies with the Maximum number of nodes parameter). These blocks must be marked as unprotected in the flashsecurity.txt file.
