About the Exosite Arduino Library

This library allows you to quickly and easily connect your Arduino project to Exosite's Data Platform in the cloud. It connects your project using an Arduino Ethernet shield, Arduino WiFi Shield, or any other networking shield that subclasses the Client class. See the examples folder for both an Ethernet and a WiFi example.

Note: A free account on exosite portals is required: https://portals.exosite.com

Tested with Arduino 1.0.5 and 1.5.5

Requirements

  • Arduino IDE must be installed on your computer Arduino IDE
  • Need an internet enabled Arduino system, which is typically done by adding a Ethernet or WiFi.
  • Note: Cellular shields typically will not work with this library as is. They typically require direct AT commands sent to open sockets, send date, etc. The libraries code can be used as reference for what needs to be sent over the modem connection.

Installing

Arduino IDE v1.6.2 or greater

Newer versions of the Arduino IDE include a Library Manager GUI that you can use to easily install the Exosite library. Simply open the Library Manager: image Next, search for and install the Exosite library: image When updates are pushed to this repository, return to this interface if you would like to update the Exosite library to the newer version.

Earlier versions of the Arduino IDE

The easiest way to install this library with earlier versions of the Arduino IDE is to simply clone this repo straight to your libraries folder.

cd ~/sketchbook/libraries
git clone https://github.com/exosite-garage/arduino_exosite_library.git Exosite

If you would rather not use the command line or you don't have git installed, click the download button on the right hand side of this page and choose to open the ZIP. Copy the contained folder to your Arduino IDE's libraries folder (inside your sketchbook folder) and Rename it to "Exosite". If you do not know the location of sketchbook folder click on "File->Preferences" in the IDE and you should see it listed.

Note: You will need to restart the Arduino IDE after installing the library.

Examples

This library includes examples, which will be available in the Arduino IDE 'Examples' menu directory.

Interface

Constructor

Exosite(Client *_client);
Exosite(char *_cik, Client *_client);
Exosite(String _cik, Client *_client);

_cik: This is used to hard code the CIK into the device can either be a char[] or a String type. This parameter can be omitted when using provisioning.

_client: This is the interface to what ever network device you're using. Must be a subclass of Client such as: EthernetClient, WiFiClient, or YunClient.

setDomain

void setDomain(const char *domain);

domain: Custom domain to connect to on next connection. eg. "myprod.m2.exosite.com"

writeRead

boolean Exosite::writeRead(char* writeString, char* readString, char** returnString);
boolean Exosite::writeRead(String writeString, String readString, String &returnString);

writeString: This sets the values to write to certain datasources. eg. "alias3=value3&alias4=value4"

readString: This selects which datasources to read by their alias. eg. "alias1&alias2"

returnstring: This is the string returned with the values requested in readString. eg. "alias1=value1&alias2=value2"

provision

boolean Exosite::provision(char* vendorString, char* modelString, char* snString);

vendorString: The string that identifies the device vendor name.

modelString: The string that identifies the device unique model ID.

snString: The string that identifies the device's serial number.

time

unsigned long Exosite:time();

Returns the current time as a unix timestamp (number of seconds since 1970-01-01) or 0 for error.

begin (ESP8266 Only)

void Exosite::begin();

Must be called before any other library calls, but after EEPROM.begin() when using provisioning.

Use only if using the following constructor:

Exosite(Client *_client);

Migration from V1

Version 2 no longer sets up the ethernet shield for you. In your code you'll need to replace Exosite exosite(&Ethernet, macData, cikData); with

class EthernetClient client;
Exosite exosite(cikData, &client);

You will also need to remove exosite.init(); and add Ethernet.begin(macData); to your setup() function.

v2.3.4 - Release 2015-08-10

  • Fixed time() function, actually returns time now.
  • Added example to use time().
  • Added library.properties for new IDE versions.
