Hello,

I understood that the application was using the space in VS1 for peering data and also for bleprofile_*NVRAM.

But what is the physical offset from VS1  those functions are using on the EEPROM ?

I would like to access directly the EEPROM via bleappfwu_*Mem and store some information in this VS1 area without messing with the application.

How much do I have left on the 1024 bytes area and at which offset ?

You should always use bleprofile_*NVRAM functions add/modify/delete items to the VS. If you use bleappfwu_*Mem functions with addresses in the VS area, there is a very good chance that you will lose pairing information at best or brick the device at worst.
