Get your access API

• username password
  • Make sure you have an account created by your smartphone. You should be see your garden: myflowerpower.parrot.com.
• client_id client_secret
  • Sign up to API here, and got by email your Access ID (client_id) and your Access secret (client_secret).

How to install

This program works with any BLE-equipped/BLE-dongle-equipped computers as well. To install it on your raspberry is really easy. You require Node (with npm) and BLE libraries.

First, you need a raspberry with a USB BLE dongle. This raspberry must be up and running. Then you need to install some required tools on your raspberry.

Step 1: NodeJs

First, nodejs needs to be installed, proceed as following:

$ wget http://node-arm.herokuapp.com/node_latest_armhf.deb
$ sudo dpkg -i node_latest_armhf.deb

Then do a node --version to check if it worked.

Step 2: BLE libraries

Then we need to install the BLE libraries:

$ sudo apt-get install libdbus-1-dev libdbus-glib-1-dev libglib2.0-dev libical-dev libreadline-dev libudev-dev libusb-dev glib2.0 bluetooth bluez libbluetooth-dev

The command hciconfig will be show your dongle (hci0):

$ sudo hciconfig hci0 up

You should be able to discover peripheral around you. To check it, do sudo hcitool lescan and if it shows you a list of surrounding BLE devices – or at least your Flower Power -- it works fine. If not, do sudo apt-get install bluez and try again.

Step 3: Build the brigde

Now Nodejs and BLE libraries are installed.

Ready to use it

If you have cloned this project, install:

$ ./install.sh

Edit credentials.json:

{
	"client_id":		"...",
	"client_secret":	"...",
	"username":		 	"...",
	"password":			"..."
}

And walk on the brigde:

$ ./bridge display			 : To have a output:
$ ./bridge background		 : To run the program in background
$ ./bridge restart			 : To restart the program
$ ./bridge status			 : To show the status
$ ./bridge stop			     : To stop the program
$ ./bridge					 : To have help

How it works

• Login Cloud
• Loop (every 15 minutes by default)
  • Get Inforamtions from Cloud
    • Your garden
    • Your user-config
  • For each of your FlowerPowers (1 by 1)
    • Scan to discover the Flower Power
    • Retrieve his history samples
    • Send his history samples to the Cloud
• End Loop

The program relive a new Loop only if all Flower Powers have been checked.

Quick started for developers

If you have this module in dependencies:

$ npm install node-flower-bridge

var bridge = require('node-flower-bridge');
var credentials = {
	"client_id": "...",
	"client_secret": "...",
	"username": "...",
	"password": "..."
};

bridge.loginToApi(credentials, function(err, res) {
	if (err) return console.error(err);
	bridge.all('synchronize');
	bridge.live('...', 5);
	bridge.synchronize('...');
});

bridge.on('newProcess', function(flowerPower) {
	console.log(flowerPower.uuid, flowerPower.lastProcess);
});
bridge.on('info', function(info) {
	console.log(info.message);
});
bridge.on('error', function(error) {
	console.log(error.message);
});

The bridge is a continual queud. Method like .all .synchronize or .live push back to this queud.

Events

'login' = {access_token, expires_in, refresh_token}
'info' = {message, date}
'error' = {message, date}
'newState' = state
'newProcess' = {uuid, lastProcess, process, lastDate}
