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:

I just realized why you got that when testing with the example. It's simply because the phone automatically disconnect after it finish bonding if you are using Bluetooth setting to bond. It's normal behaviour of the phone. If you want to keep the connection after bonding, you should use an app, nRFConnect for example, to request to bond and then you can have the connection kept after that.
