Kindle Apps & Services

The Kindle has many apps/services which communicated via LIPC, which is similar to dbus in many respsects.

LIPC values are wrapped in square brackets (`[]`), these should be excluded when writing to a LIPC entry

How to use

LIPC can be interacted with through the command line as so:

lipc-set-prop <name> <property> <value> # Set a property value

lipc-set-prop com.lab126.powerd preventScreenSaver 1 # Disable screensaver
lipc-set-prop com.lab126.appmgrd start app://com.lab126.booklet.home # Open the home "app"



lipc-get-prop <name> <property> # Get a property value

lipc-get-prop com.lab126.btfd isBtchRunning # Check if BTch is running

Identifying what process owns a service

To get the pid of the process that owns/registered a service, the following command can be used (where <name> is the name of the service, such as com.lab126.btService):

dbus-send --system --print-reply --dest=org.freedesktop.DBus / org.freedesktop.DBus.GetConnectionUnixProcessID string:<name> # Longer Command

gdbus call -y -d org.freedesktop.DBus -o / -m org.freedesktop.DBus.GetConnectionUnixProcessID <name> # Slightly Shorter Command

Then, you can use ps -p <pid> to get the name of the process, or use ps u -p <pid> to get the full process command line.

List of apps/services

The following list was obtained via the following command run on the Kindle:

lipc-probe -a -v
