LE Secure Connections compatible with Android

[VanNuru]

I have my own BLE application on the nRF52832 with SDK 11 and SD 2.0.0 that communicates to my own android app on a sony xperia z3 compact. The Android version is 6.0.1 and the tech-specs of the xperia say it's bt 4.0 compatible.

I'd like to implement Secure Connections Pairing because LE Legacy Pairing is insecure. As BT 4.2 is supposed to be only a software update from 4.1 and 4.0, I thought it could be possible with my Android version. Unfortunately, I cannot find any notes about any Android version supporting BT 4.2 and if I activate LE Secure Connections in my nRF, the pairing does not work.

Has anybody succeeded trying to implement LE Secure Connections for communication with an Android device?

Thanks for the input. As my service characteristics require encryption and mitm protection, using a less secure pairing would not happen, I guess.
