Hi,

You can call bt_conn_get_info() from your "security changed" callback to check if the BT_SECURITY_FLAG_SC bit has been set in bt_conn_info->security.flags have been set.

Hi Vidar,

Good day!

Thank you for confirming that, by default, BLE pairing automatically enables LE Secure Connections (LESC) when pairing is enabled. I compared this with the nRF5 SDK, where we need to explicitly enable LESC for LE Secure Connections.

I need to verify that LESC is working. How can I confirm that my project is using LESC?

LESC pairing is automatically enabled when you enable pairing in nRF Connect SDK projects. It will only fall back to legacy pairing if the central does not support LESC. How do you determine that legacy pairing is used?

HI,
I need a conformation that ,I am in a right path.
and also I need to know how to implement LESC for this.
