    Encrypt characteristics without encryption permission


      We are currently developing the BLE that needs to have 2 modes: 1 is the test mode that do not need authentication and encryption, with only limited access of some  services and characteristics. Another one is normal mode, which require authentication and encryption, with full access to all services and characteristics.

      As the ROM size and RAM size are approaching limit, I cannot export the GATT database to modify the permission to achieve the requirement.


      However, I would like to know if the characteristics permission is set to "No Encryption required" and "No Authentication Required", will the data still be encrypted if the peripheral still paired/ bonded with the central?


      All advise greatly appreciated.
