ProtoPie Connect

ProtoPie Connect is an extension app available in ProtoPie’s Pro and Enterprise plans. Prototype any real-world scenarios involving multiple devices, displays, hardware, and APIs seamlessly. ProtoPie Connect serves as the glue that holds everything together.

Install ProtoPie Connect and build your dynamic prototyping environment where prototypes running on various devices can communicate. Because today’s digital experiences go beyond a single laptop or mobile screen.

Let's take automotive as an example. In the following video, tapping a button on the center display triggers animations on the cluster and head-up display (HUD). This is possible thanks to the flexibility and power of ProtoPie Connect.

How ProtoPie Connect Works

At its core, ProtoPie Connect acts like a communication server connecting multiple clients:

• ProtoPie prototypes running on smart devices (iOS, Android)
• ProtoPie prototypes running on web browsers on desktops
• hardware systems (e.g., Arduino, Logitech G29 steering wheel)
• external services (e.g., IFTTT webhooks, public APIs)

The clients can communicate locally, through a localhost server, or within a local area network (LAN). ProtoPie Connect listens on port 9981 on all the IP addresses of the machine it runs on. You can modify the assigned IP address by clicking on Network from the menu bar and selecting another IP address.

How Prototypes Communicate in ProtoPie Connect

Communication between multiple devices connected via ProtoPie Connect occurs through Send and Receive messages. It’s the same messaging system used to pass information back and forth between scenes and components, and to create interactions between two devices using ProtoPie Studio as a hub (connecting devices).

You can send out messages to prototypes or hardware devices using the Send response. For other prototypes to hear such messages and respond accordingly, you need to use the Receive trigger.

It is important that both Send and Receive are set up to use the same channel in ProtoPie Studio. For prototypes communicating through ProtoPie Connect, the channel must be ProtoPie Studio.

Connect Desktop vs. Connect Embedded

There are two different types of ProtoPie Connect:

• Connect Desktop
• Connect Embedded

Connect Desktop runs on macOS and Windows. It allows you to run multiple prototypes simultaneously and create immersive multi-screen experiences. It includes built-in plugins to integrate ProtoPie with external hardware devices and services, including Arduino and IFTTT. Enterprise plan users can also upload their own custom plugins to create even more unique digital experiences.

Learn more about Connect Desktop and its API, IFTTT, G29, Arduino, Gamepad, blokdots, and custom plugins.

As its name suggests, Connect Embedded is designed to run on embedded systems such as Raspberry Pi. It’s a standalone server application that runs in the terminal. Connect Embedded is only available within the Enterprise plan.
