Arduino Cloud Library

Use this library to connect your Arduino/Genuino to Arduino cloud. To have your configurations ready follow the getting started or go to the cloud dashboard.

1. Supported devices

1.1. Zero + WiFi101, MKR1000

Important

Make sure to have the correct SSL certificate for arduino.cc. Look here for the the update instuctions.

1.2. Yun-Shield

Important

The yun or yun shield firmware should be >=1.6.2. Look here for the the upgrade instuctions.

2. Credits

The library is based on the Paho Library.

Special thanks to Joël Gähwiler author of arduino-mqtt library for his work on porting the paho library on Arduino.

3. APIs

3.1. Setup and Configuration

• ArduinoCloudThing()

• void begin(const char* name, const char* username, const char* id, const char* password, Client &client)

3.2. Property configuration

3.2.1. Simple property

• void addProperty(const char* name, const char* datatype, const char* permission)

3.2.2. Policy managed property

Is possible to specify a policy as:

• ON_CHANGE: the value will be written only if it is changed

• TIMED: is necessary to specify a lapse (seconds)

• void addProperty(const char* name, const char* datatype, const char* permission, const char* policy)

• void addProperty(const char* name, const char* datatype, const char* permission, const char* policy, int lapse)

3.2.3. Other object property

An object can also read or write a property of another object, is just necessary to specify the other object’s name

• void addExternalProperty(const char* other_device_name, const char* name, const char* datatype)

3.3. Write properties

• void writeProperty(const char* name, char* value)

• void writeProperty(const char* name, float value)

• void writeProperty(const char* name, int value)

• void writeProperty(const char* name, String value)

3.4. Read properties

• String readProperty(const char* name)

• String readProperty(const char* other_device_name, const char* name)

3.5. Extra

• void poll()

• void push()

• void enableDebug()

• void disableDebug()

4. Variables

4.1. Permissions

• R - The property can be only written from the device

• RW - The property can be written and from the device and can update the value from other objects

4.2. Polices

• TIMED - Waiting seconds before update a new data

• ON_CHANGE - Publish value only on change

4.3. Data Type

4.3.1. Standard

• CHARSTRING

• FLOAT

• INT

4.3.2. Temperature

• TEMPERATURE_C - celsius

• TEMPERATURE_F - fahrenheit

4.3.3. Lenght

• LENGHT_M - meters

• LENGHT_C - centimeters

• LENGHT_I - inches

4.3.4. Vars

• PERCENTAGE

• ANALOG

• LUMEN

• PPM - gas part per million

• STATUS - on/off

5. Debug

The default debug output is on SerialUSB, in order to change the output is necessary to edit CLOUD_DEBUG_SERIAL at the begin of src/ArduinoCloudThingBase.h

arduinocloud's Issues

Still in development?

I've been playing around with the Cloud offering and haven't been able to make it work. It looks like this library hasn't been updated in a while and there's pretty much no documentation on the board I'm using (MKR WIFI 1010) or the Cloud offering. Need some help with the docs? I'm happy to help.
