This plugin enables Essentials to communicate with the Mobile Control User App.
This happens via two methods:
- An Edge Server running the Mobile Control API stack to enable user provided mobile devices to choose and control rooms using either the QR code or numeric user code mechanism
- If using a 4-series processor, the processor can run a websocket server that allows direct communication from dedicated in-room devices.
Both methods are optionally configurable and can operate independently or in parallel.
A user gets served the Mobile Control User App to their browser via HTTP and subsequently a websocket connection is made to the plugin to allow serial communcation for realtime system control and feedback.
PepperDash Essentials - Releases (v2.0.0 minimum)
PepperDash Mobile Control React App Core - Releases
The steps below detail how to load Mobile Control on a 4-Series processor running a websocket server to be served to local devices like an in-room touchpanel or a dedicated room PC or tablet. Devices that connect in this manner can only connect to a single room, configured by generating a token via console commands on this plugin.
An Edge Server can still optionally be used for mobile devices to connect to any room configured to communicate with the Edge Server.

The room-key value must match the key of a room defined in the rooms array of the running Essentials configuration file.
Each connection requires a unique Token that serves to differentiate between unique user interfaces, allowing selective updates and unique user experience sessions on unique devices.

The included library mobile-control-messengers contains the MessengerBase class and a set of messengers that correspond either to common abstract base classes or to specific interfaces and are used to generate a dynamic API for the User Interface client applications to integrate with.
As part of the Essentials program startup cycle, this plugin will iterate through the loaded devices and rooms and attempt to create messengers for each device for every base class or interface that device can successfully be cast as.
In addition to the automatically instantiated messengers, plugin devices can reference the mobile-control-messengers project via nuget as a dependency and thus inherit from the MessengerBase class to create custom messengers. These custom messengers will have to be manually added to the MobileControlSystemController instance.
To view the paths at runtime, the console command mobilecontrolshowactionpaths:[slotnumber] will print all the action paths for the mobile control API.
