Does gecko_sdk_suite v2.4 support the level-2 of security mode 2 run at EFR32BG13. Below is the description for security mode 2
Security Mode 2:
This mode enforces security by means of data signing, and contains two levels:
Level 1 - Unauthenticated pairing with data signing
Level 2 - Authenticated pairing with data signing
No, that is not supported as it's less secure than data encryption.
