Move this page: https://learn.adafruit.com/welcome-to-adafruit-io/securing-your-io-account to documentation. It should be screenshot-less.

Then, unpublish that page in the guide.

here it explains how to delete a group. However, the curl example does not include the DELETE command and defaults to GET.

It should be like this:

curl -X DELETE -H "X-AIO-Key: xxx" ...

Clicking on the API documentation returns a blank page

I'm trying to find my AIO key, but it is not listed anywhere that I can find. The left menu options that are listed here https://io.adafruit.com/api/docs/#about-the-api-docs and elsewhere are not available on my screen (see screenshot). I see Devices, Feeds, Dashboards, Actions, Power-Ups. Am I looking in the wrong place? Thanks!

{"error":"not found - You are not permitted to access the feed with key 'switchfeed' belonging to embeddednani or the feed does not exist."}

Chirpstack is expecting a certificate before setting up MQTT connections. Any suggestions?

Went through Web server tutorial from http://easycoding.tn/index.php/esp32/esp32-internet/

code I ended up with
#include "Adafruit_MQTT.h"
#include "Adafruit_MQTT_Client.h"
#include "Adafruit_MQTT_FONA.h";
#include <WiFi.h>

int i;
#define AIO_SERVER "io.adafruit.com"
#define AIO_SERVERPORT 1883
#define AIO_USERNAME "rnborland"
#define AIO_KEY "ffe00a15e69a4c59890308a811faf8b3"
WiFiClient client;

Adafruit_MQTT_Client mqtt(&client, AIO_SERVER, AIO_SERVERPORT, AIO_USERNAME, AIO_KEY);

boolean MQTT_connect();

boolean MQTT_connect() { int8_t ret; if (mqtt.connected()) { return true; } uint8_t retries = 3; while ((ret = mqtt.connect()) != 0) { mqtt.disconnect(); delay(2000); retries--;if (retries == 0) { return false; }} return true;}

Adafruit_MQTT_Publish Testing = Adafruit_MQTT_Publish(&mqtt, AIO_USERNAME "/feeds/Testing");
void setup()
{

Serial.begin(9600);

WiFi.disconnect();
delay(3000);
Serial.println("START");
WiFi.begin("Borland","d5cs7xk1");
while ((!(WiFi.status() == WL_CONNECTED))){
delay(300);
Serial.print("..");

}
Serial.println("Connected");
Serial.println("Your IP is");
Serial.println((WiFi.localIP()));

}

void loop()
{

i = (random(100,200));
if (MQTT_connect()) {
  if (Testing.publish(i)) {
    Serial.println("Random Data Sent");
    Serial.println(i);

  } else {
    Serial.println("Problem Sending Data");

  }

} else {
  Serial.println("Connection Problem");

}
delay(10000);

}

I am trying the "VGAHelloWorld " example from Bitluni esp32Lib.

I have been facing this issue

error: invalid conversion from 'int' to 'timer_alarm_t' [-fpermissive]
config.alarm_en = 1;
error: invalid conversion from 'int' to 'timer_autoreload_t' [-fpermissive]

Kindly let me know how to solve this.

The description on https://io.adafruit.com/api/docs/#adafruit-io-http-api says I can find the API key from any dashboard, but I do not see the row of icons referred to in the description. Eventually, I found that the dashboard has a key icon in the top right. So it is not as I described. Maybe the main problem is that I expected the API key to be accessible from the Feeds page, not the dashboards.

import time
import serial
from Adafruit_IO import Client
aio = Client("vishprao", "")

ADAFRUIT_IO_USERNAME = "vishprao"

ADAFRUIT_IO_KEY = ""

ser = serial.Serial(

port='/dev/ttyUSB0',

baudrate = 9600,

parity=0,

stopbits=1,

bytesize=8,

timeout=1

)

ser = serial.Serial('/dev/ttyUSB0')
while True:
data =[]
for index in range(0,10):
datum = ser.read()
data.append(datum)

pmtwofive = int.from_bytes(b''.join(data[2:4]), byteorder='little') / 10
aio.send('kingswoodtwofive', pmtwofive)
pmten = int.from_bytes(b'',join(data[4:6]), byteorder='little') /10
aio.send('kingswoodten', pmten)
time.sleep(10)

The "Title" of the project, at the top of the GitHub page says this:
API documentation for Adafruit IO (https://io.adafruit.com/api/)

when I go to that address, it gives me a message that says:
