D-Bus must be configured to grant us permissions to do this. We'll grant these permissions to user `root`. + +You'll need to locate the D-Bus permissions on your box.

If you change the service name from `gobbledegook` to `clownface` in that call to `ggkStart()`, then you'll need to edit the `gobbledegook.conf` file and change all occurrances of `com.gobbledegook` to `com.clownface`. + ### Enabling Bluetooth You don't need to do anything. this server will automatically power on the adapter, enable LE with advertisement. |
