AdafruitAIO

AdafruitAIO is a special class the inherits from AdafruitMQTT (described earlier in this learning guide). It takes the

core features from AdafruitMQTT and adds some helper functions that make working with Adafruit

IO (https://adafru.it/fsU) easier.

Constructor

Parameters:

username: The username associated with your Adafruit IO account (normally visible here (https://adafru.it/dyy)).

password: The Adafruit IO key associated with your account. This is available by logging into Adafruit IO and

clicking the yellow 'key' icon labelled 'Your secret AIO key'.

Functions

In addition to the functions defined in the AdafruitMQTT base class, The following functions are included as part of

AdafruitAIO:

Connecting

The following functions are available to connect to the Adafruit IO server:

bool connect (bool cleanSession = true, uint16_t keepalive_sec =

If you're unfamiliar with Adafruit IO have a look at our introductory learning guide here:

AdafruitAIO(const char* username, const char* password)

By default AdafruitAIO will generate a random 10..23 character string for the ClientID. If required you can

override the default value via the .clientID function if it is called BEFORE the .connect or .connectSSL

functions.

bool connect ( bool cleanSession = true,

uint16_t keepalive_sec = MQTT_KEEPALIVE_DEFAULT )

bool connectSSL ( bool cleanSession = true,

uint16_t keepalive_sec = MQTT_KEEPALIVE_DEFAULT )

bool updateFeed ( const char* feed,

UTF8String message,

uint8_t qos=MQTT_QOS_AT_MOST_ONCE,

bool retain=true )

bool followFeed ( const char* feed,

uint8_t qos,

messageHandler_t mh )

bool unfollowFeed ( const char* feed )
