Feature request bluetooth / offline mode?

It'd be great if you could post up the contents of your setting.json and .boot0 files when you've done a make connectable : no.

Looking at the code, it should set ble=false in settings, which should add the line if (!NRF.getSecurityStatus().connected) NRF.sleep();, so it should be that if you're not connected, as soon as you leave the settings app it turns bluetooth off.
