Ah right, that's the thing I'm missing, Classic vs BLE. Thanks.

That is the bluetooth stack on both devices. This is more on the Bluetooth Classic side of things not BLE.

Thanks for your quick response.
When I do a scan with a tablet it will detect my phone as a device that is in range, without any app running on that phone. So my simple conclusion would be that it should also possible using the nrf51822. But I'm probably missing something.

The phone has to be either scanning or advertising. This would require any app. You could have your device either detect a Scan Request if the phone is scanning, or have your device scanning to detect a phones advertisements. Either way you will need an app on the phone, with the App running in the foreground.
