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?

Hi VanNuru

I had some similar problem with LESC compatibility on Android devices.

Today it is still a big problem due to the diversity of criteria by the manufacturers.

As you comment, LESC is supposed to be a simple software update of the BT 4.0 or 4.1, but I'm very dissapointed with the manufacturers policy about updates, even more, considering this as a security update.

Have you any model/manufacturer list of LESC compliant devices?

Sorry, I don't, and I didn't really do much more research on that problem since I posted this.

It's OK.

I posted this new thread because of this problem:
