    [EZ-Serial Firmware for CYW2070x-based Modules] Encryption start trigger




      Please tell me about the trigger to start data encryption of EZ-Serial Firmware.


      I think there are three ways to encrypt.

      1. A case where pairing is performed by performing pairing from Central (pairing starts with "settings" of a smartphone etc.), and encrypted communication is taken over as it is.

      2. A case where Central accesses a characteristic that has peripheral security enabled, and Central starts encryption when Insufficient Authentication is returned.

      3. A case where the central starts encryption by sending a "slave security request" to the central after the peripheral connects.


      I think Case 1 supports it. (Because it is normal encryption)


      Are 2 and 3 supported by CYSPP Profile (CYSPP Service)?


      Best regards,
