This application connects with CMD and AFR devices using the Android device's bluetooth connection. Through these devices you can view states and send commands to perform actions (you must have a CMD previously installed in the vehicle).
In the case of AFR, the reading of the lambda probe can be displayed in real time, and alternate between displays of Lambda Factor, or AFR for gasoline or CNG. The possible commands are useful for configuring RGB colors or brightness of the LED indicators, or the brightness of the numerical display, in addition to turning each element on and/or off. Very useful for performing tuning tasks from the engine compartment by observing the probe readings from your mobile device.
In the case of the CMD, it allows you to view the general status of the vehicle: doors, lights, alarm, central locking, ignition, engine running and engine rpm. You also have the ability to control all of these elements from the app.
