@T-vK Can you please merge this PR and update the release version?

This PR fixes unsuccessful pairing issues for ESP32-C3 (I don't have a S3 to test):

E (19075) BT_SMP: smp_calculate_link_key_from_long_term_key failed to update link_key. Sec Mode = 2, sm4 = 0x00
E (19076) BT_SMP: smp_derive_link_key_from_long_term_key failed

E (19082) BT_BTM: btm_proc_smp_cback received for unknown device

I'm having a problem where everytime i try to connect is doesn't work and says "try to connect again"

On my 32 dev kit it works fine, so i think it has to be with the C3 super mini i'm using Already did all the changes
