Hi Travis, > I’m intersted in setting the name of my device, when I’m acting as a BLE Peripheral.

So I’d have to modify the file after I have gotten that information, and then restart the service. Not undoable, but far from elegant. > 2) Though hciconfig will show back the name set, it doesn’t seem to actually show up when I scan. > 3) Not sure how I figure out what the dbus interface is. Is this documented anywhere? Or does one just explore and guess with tools? Maybe it’s too early in the experimental phase to really document? if you are actually more into the BLE space, then the LE Advertising D-Bus API is something you might want to look into. With a recent kernel and recent BlueZ, you can build your own advertising reports and include more dynamic naming if you want to. Otherwise there is also a plugin mechanism for setting the device name. That is a preferred one and for example on a system running systemd-hostnamed it will take the device name from there. You could write your own plugin.
