AssetTracker iOS

Note: This was create as an opensource project for the particle community, but mainly to track my dog Sheldon. He likes to escape for a few hours... -_-

The application is using webhooks to store the particle publish events to firebase. This way the app will not need to be open to receve/store the incoming data.

Getting Started

Prerequisites

You will need the GoogleService-Info.plist to run the application. In addition, you also need to add a webhook to the particle console.

But first go to to firebase.google.com and create a new iOS project. Follow the instructions till you get the GoogleService-Info.plist drag and drop it into you project.

Note

A better more well documented way to add firebase to your project can be found here,
but keep in mind you will need to use the following json block in your webhook for the app to function.

---

Create a new text document with the following json. You will need to change the url field and the auth field to the ones that correspond to you firebase project.

{
    "event": "test1data",
    "url": "https://FakeURl.firebaseio.com/test1data/data.json",
    "requestType": "POST",
    "query": {
    	"auth":"vuwiefbwiufbwiuefbuw2F2HRPUBt0FOyY"
    },
    "json": {
      "G": "{{G}}",
      "B": "{{B}}",
      "t": "{{PARTICLE_PUBLISHED_AT}}"
    },
    "mydevices": true,
    "noDefaults": true
}

You can then create the webhook using the Particle CLI and a command like:

particle webhook create hook.json

keep in mind the file name needs to be hook.json and it has to be in the same dic where you are calling the command from.

The Electron code.

It's litrally the same as the GPS_Features example, But with a custom publish for the coordinates and battry percent You can find the gps-features src in the main dic of this repo.

char buf[42];
snprintf(buf, sizeof(buf), "{\"G\":\"%f,%f\",\"B\":\"%.2f\"}",t.readLatDeg(),t.readLonDeg(), fuel.getSoC());
Serial.printlnf("publishing %s", buf);
Particle.publish("G", buf, PRIVATE);

Flash the Electron

If you want to try it out you can just flash the Electron with the firmware.bin file locaded in the gps-features folder.

particle flash --serial fullpath_of_bin.

Built With

• Firebase - The backend
• JLTGradientPathRenderer Gradient path. It's nice but not what I wanted, will replace in the fureture
• HalfModalPresentationController HalfViewController. Not perfect but it works for now
