Feed send failures

by eehite on Mon Feb 29, 2016 8:02 pm

Evening all,

I have just started playing with the Adafruit REST libraries, and have so far been unable to get any operations to work.

Code: Select all | TOGGLE FULL SIZE
#include <SPI.h>
#include <Ethernet2.h>

#include "Adafruit_IO_Client.h"

#define AIO_KEY  " key is here..."

byte mac[] = { 0x90, 0xA2, 0xDA, 0x10, 0x30, 0xD1 };

EthernetClient client;

Adafruit_IO_Client aio = Adafruit_IO_Client(client, AIO_KEY);
Adafruit_IO_Feed testFeed = aio.getFeed("test");

int value;

void setup()

  if (Ethernet.begin(mac) == 0)
    Serial.println(F("Ethernet Connection Failed"));


void loop()
  for (int i = 0; i < 100; i++)
    if (testFeed.send(value))
      Serial.println("sent value");
      Serial.println("send failed");

Am I implementing this correctly? The code gets an IP just fine, but all I ever get is the send failure message and the feed is never modified.

I'm running this on an Uno with an Ethernet shield.

Thanks for any thoughts!

Hi what kind of project are you working on? What kind of data are you trying see on IO.adafruit? Did you ever get it to work?
