PepperDash.Essentials.Plugin.MobileControl.Messengers 4.3.3

Mobile Control Essentials Plugin

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.

Direct Connection to 4-Series Processor with or without Edge Server

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.

Configuration Snippets

_config.local.json

This file is created automatically when program starts up and served up to the client device as part of the Mobile Control app. It contains the information to configure the app and to connect to the processor via websocket.

{
  "apiPath": "http://{processor-ip}:{50000 + Essentials Slot #}/mc/api", // This value must be set to the IP of the processor and the port configured for the websocket
  "gatewayAppPath": "https://{processor-ip}:{50000 + Essentials Slot #}/mc/gateway", // Not used in direct connection scenarios
  "enableDev": true,
  "logoPath": "logo/logo.png",

properties.directServer.port is 50,000 + Essentials Slot # and should be the same port used in the apiPath and gatewayAppPath URLs of the _config.local.json file.

Mobile Control Plugin Configuration on 4-Series Processor Using Console Commands

Add/Remove UI Client for Direct Communication

mobileadduiclient(:essentials-slot-#) {room-key} {grant-code} // currently the grant code is not enforced. Any string can be used

// example
mobileadduiclient:1 room1 AOIUYGHG

mobileremoveuiclient(:essentials-slot-#) {token} // removes the ui client matching the specified token

// example
mobileremoveuiclient:1 81c4eb3c-dbc5-410c-8816-90500f474236

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.

Get Mobile Control Info

The following commands gets the current mobile control info. The Client URL is needed for the Crestron TS(W) General Web URL field to run on a TS(W) panel directly.

// get mobile control info
mobileinfo

// exmaple mobile control info response

Messengers for communicating between Essentials Devices and the Client User Interface

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.
