LESC example with Android

[Rocky]

I am having trouble getting the experimental ble_app_multirole_lesc example working with Android and nRF Connect. It is working fine in iOS. I am using v12.1.0 of the SDK and the nRF Connect app for both tests.

Does anyone know if LESC is yet supported in Android?

The log output looks as follows:

After further troubleshooting, I am now able to get it to work.

It is not entirely reliable, but I can get it to work after removing bonding keys on both the phone and the DK board. I am also disabling/enabling BLE from Android settings between tests. I am then able to bond using the ... button in the upper right hand corner of the nRF Connect Android app.

To complete the pairing process, I press button #1 on the DK board and accept the bonding prompt in the nRF Connect app. It sometimes immediately disconnects, but the bond is successful and I am able to immediately reconnect.
