#Arduino Notifyr Client

###An Arduino client for connecting to notifyr.io using the Ethernet or WiFly Shields

Notifyr is a simple cloud based service to quickly and easily add realtime push functionality to web and mobile apps.

#Installation

• Clone (or Fork & Clone) ArduinoNotifyrClient
  • example: git clone git://github.com/dubhunter/ArduinoNotifyrClient.git
• Copy (or Symlink) ArduinoNotifyrClient to Arduino/libraries
  • example: ln -s ~/Projects/ArduinoNotifyrClient ~/Documents/Arduino/libraries/ArduinoNotifyrClient
• Restart Arduino IDE

###Example

mkdir -p ~/Projects/ && cd ~/Projects/
git clone git://github.com/dubhunter/ArduinoNotifyrClient.git
ln -s ~/Projects/ArduinoNotifyrClient ~/Documents/Arduino/libraries/ArduinoNotifyrClient

#Configuration

###Enabling WiFly Shield

• Uncomment #define _WIFLY_ in NotifyrClient.h
• Restart Arduino IDE

#Examples

Included with this library are two simple examples NotifyrSerial and NotifyrSerialWiFly for the Ethernet Shield and WiFly Shield respectively. They both do the same thing: Connect to my-channel channel and print all events to Serial.

###Instantiation

//Create a NotifyrClient (which will have its own Ethernet or WiFly client)
NotifyrClient notifyr;

###Connect & Bind

if (notifyr.connect(NOTIFYR_KEY, "my-channel")) {
    notifyr.bind(handleEvent);
} else {
    //failed to connect
}

###Listen

void loop() {
    //listen for incoming events
    notifyr.listen();
}

###EventDelegate

void handleEvent(String data) {
    //do something with your data
    Serial.println(data);
}

###Debug (or just see cool info)

begin() {
    Serial.begin(9600);
    NotifyrClient::debug();
    
    //connect & bind...
}

#API

The NotifyrClient exposes a very simple API.

###bool NotifyrClient::connect(String key, String channel);

Connect to Notifyr on a specific channel. Automatic re-connects are attempted if we miss two heartbeats.

###bool NotifyrClient::connected();

Check to see if you are currently connected to Notifyr.

###void NotifyrClient::disconnect();

Disconnect from Notifyr.

###void NotifyrClient::bind(EventDelegate delegate);

Once you have connected, bind your event delegate to be called when an event is received. EventDelegate's have the signature void myDelegate(String data);

###void NotifyrClient::listen();

Listen for incoming events. This MUST be placed in your loop() function.

###NotifyrClient::debug();

Turn on logging (Serial.begin() required);

#Caveats

• I do not know C++
• Does NOT handle multi-line payloads.
• If your payload includes data: ", everything will break. You can use "data": " for more complex payloads.
• If you hold the main loop() for more than 60 seconds, you may cause the heartbeats to be missed, and cause a reconnect attempt.
  • If this is a problem, change NotifyrClient::HEARTBEAT_THRESHHOLD to something higher in NotifyrClient.h
