User Manual

fp: The callback handler function that will be fired when the feed changes on the AIO server. This function

should have the following signature:

Returns: 'True' (1) if the operation was successful, otherwise 'false' (0).

bool unfollow (void)

Calling this function will stop the follow callback and unsubscribe from the feed, meaning any changes will no longer

be received by this class.

Parameters: None

Returns: 'True' (1) if the operation was successful, otherwise 'false' (0).

bool followed (void)

Checks whether 'follow' is currently enabled or not (indicate whether or not we are subscribed to the AIO feed).

Parameters: None

Returns: 'True' (1) if the operation was successful, otherwise 'false' (0).

Example

For more examples of working with AdafruitIO and AdafruitIOFeed see the /AIO folder in /examples in the WICED

Feather board support package.

The name of the callback handler function can be set to anything you like, although the parameters and

return type must be identical.

void feed_callback(UTF8String message)

{

Serial.println(message);

}
