Answer 1

Unfortunately, the official answer from Google is no, the Nexus 5 no longer supports advertising.

We introduced BLE peripheral mode in Android 5.0 Lollipop. Nexus 6 and Nexus 9 are the first two production Nexus devices that support BLE peripheral mode. Due to hardware chipset dependency, older Nexus devices (4/5/7) will not have access to the feature on Lollipop.

See Comment #52 on issue 1570 by danielho...@google.com: BLE advertise mode not working https://code.google.com/p/android-developer-preview/issues/detail?id=1570

That said, I have confirmed that advertising is supported by the Nexus 9 tablet. See here for details: http://developer.radiusnetworks.com/2014/11/18/beacon-transmission-with-android-5.html
