Create an IPhone App That Talks to Particle Mesh

In this project, you'll learn how to load an app on your iPhone that talks directly to a 3rd Generation Particle Mesh board. It will take less than 20 minutes of your time. Plus, you can start tinkering right away!!

Let's get started.

Things you'll need

• Particle Mesh (Xenon, Argon, Boron) board
• Newer iPad or iPhone. (That's it!)

Getting setup

Getting setup will be the trickiest part.

• Install Xcode. You can download it from the App store here.
• Install Particle Workbench. You can download it here.
• You'll also need an Apple login. I use my iCloud email. You can create a new account within Xcode if you don't have one yet.

Clone the RGB firmware code to your computer

git clone git@github.com:jaredwolff/particle-bluetooth-rgb.git

Clone the App example code to your computer as well

git clone git@github.com:jaredwolff/swift-bluetooth-particle-rgb.git

• The fastest way to get started is to compile and load locally.
• Plug your Particle device into USB
• Click on ble-rgb-control.ino in the left menu
• Select the Particle device you're using in the bottom right corner. (I'm using a Xenon in this example)
• Select the deviceOS version as 1.3.0-rc.1 in the same area.
• Put the device into DFU mode.
  
  Here are some handy ways to do it without touching a single button on the mesh board:
  
  For Mac (tested)/Linux (untested)
  
  stty -f /dev/tty.usbserial1234 14400
  
  For PC:
  
  mode COMx 14400
  
  (x being the auto-assigned port number)
  
  Once you run the command, you may notice your device is blinking yellow! Good stuff!

• Command + Shift + P and then click Flash application (local)

  Note: if you are unsure which version is on your device it's best to do a CloudFlash instead of a Flash application (local). That way your OS is updated in the process as well.

• Open the project in Xcode
• Plug in and select your device

• Press play to load it

At this point the firmware should be loaded on your device. The app is loaded on your phone. You can take a look through the code and see how things were connected.
