InternetCar is an Internet of Things (IoT) sample application built on Parse. It demonstrates the usage of Parse to enable communication between an remote device and an IoT device. The IoT device could theoretically be any hardware which runs an Embedded SDK. Specifically, this application communicates with the Texas Instruments SimpleLink Wi-Fi CC3200 LaunchPad. We will refer to this device as simply 'CC3200' throughout the README. This app is adapted from the Parse AnyDevice sample app.

The device code running in the car is contained in directory cc3200.

Refer to the Quick Start for the CC3200 to get your device set up.

Create a new app on Parse. Your Application ID, Master Key, and Client Key will be available to you under Settings > Keys.

Before using the iOS application, the Parse Application and associated Cloud Code must be setup. Full instructions can be found in the Cloud Code repository.

The iOS control app is adapted from Anydevice, an App which we built for universally controlling a CC3200 device.

Anydevice requires Xcode 6 and iOS 8.

1. Install dependencies via Cocoapods by running pod install in the ios directory.

2. Open the Xcode workspace at Anydevice.xcworkspace.

3. Copy your new Parse Application ID and Client Key into PADConstants.m.

NSString * const PADApplicationId = @"YOUR_APPLICATION_ID";
NSString * const PADClientKey = @"YOUR_CLIENT_KEY";

In order to receive events that originate from a CC3200 device, you must have push notifications set up. This tutorial provides full push notification setup instructions.

Typically, Anydevice allows you to control an LED on a CC3200 device, and to view the current state of that LED. The LED has three states: On, Off, and Blinking. Using Anydevice, you can send a message corresponding to one of these states from a mobile device in order to change the LED's behavior. The LED state can also be controlled from the CC3200 itself. When the LED state is updated on the CC3200, a push notification is sent to the owner's mobile devices via Parse. This way, Anydevice can correctly reflect the current state of the LED.

In InternetCar example, we adapted Anydevice to car control instead of LED control. You have Drive, Reverse and Flashing available as long as your device name contains a word "car" when you follow the following steps to provisioning your CC3200.

In order to enable the communication between Anydevice and the CC3200 device, the CC3200 device must go through a provisioning process whereby the device registers on Parse and then connects to a wifi network. When you are adding a new device via Anydevice, you are guided through the steps needed to complete the device provisioning. An overview of the provisioning process is given below:

1. Once the '+' button on the home screen is tapped, the appropriate device objects are created and initialized on Parse.

2. After initialization, you must connect to the CC3200's wireless access point. The first step is to navigate to the Wi-Fi section in the iOS Settings application.

3. Select the network corresponding to the CC3200 device's access point.

4. Upon connecting to the CC3200 device, navigate back to Anydevice. When you do this, the connection with the CC3200 device is verified.

5. Confirm the provisioning details. These details include the wifi network SSID to which the CC3200 device should connect along with the wifi password. Again, make sure your device name constains a "car", e.g. my-internet-car, before you submit the provisioning details.

6. Send the network information to the CC3200 device. This will happen when the 'Done' button is tapped on the confirmation screen.

7. After provisioning begins, the CC3200 device will stop broadcasting its access point. Anydevice will then attempt to reconnect to a wifi network automatically.

8. Wait for the confirmation event which is sent from the CC3200 device after it provisions successfully. The provisioning flow will dismiss automatically when this event is received (the event is sent via a push notification).
