Please describe the bug / issue. Attaching any relevant screenshots would be very helpful!
Rather constant Cmd errror/Login timeout that results in all the V-pins not being polled and written before the next time out. Resulting in higher numbered Vpins never being successfully reported to the server.
I’m sure the problem is with my code, but if it could be a timeout rule that can be extended that might be nice.
The code-
// Example testing sketch for various DHT humidity/temperature sensors
// Written by ladyada, public domain
#include "DHT.h"
#define CAYENNE_DEBUG // Cayenne Code Uncomment to show debug messages
#define DHTPIN 4 // what digital pin we're connected to
#define CAYENNE_PRINT Serial // Cayenne Code Comment this out to disable prints and save space
// #include <CayenneEthernet.h> // Cayenne Code Change this to use a different communication device. See Communications examples.
#include <CayenneWiFi.h>
// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token[] = "your token";
// Your network name and password.
char ssid[] = "your ssid";
char password[] = "your password";
// Uncomment whatever type you're using!
#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22 (AM2302), AM2321
//#define DHTTYPE DHT21 // DHT 21 (AM2301)
// Connect pin 1 (on the left) of the sensor to +5V
// NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1
// to 3.3V instead of 5V!
// Connect pin 2 of the sensor to whatever your DHTPIN is
// Connect pin 4 (on the right) of the sensor to GROUND
// Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor
// Initialize DHT sensor.
// Note that older versions of this library took an optional third parameter to
// tweak the timings for faster processors. This parameter is no longer needed
// as the current DHT reading algorithm adjusts itself to work on faster procs.
DHT dht(DHTPIN, DHTTYPE);
void setup() {
pinMode(4, INPUT);
Serial.begin(9600);
Serial.println("DHTxx test!");
Cayenne.begin(token, ssid, password);
dht.begin();
}
void loop() {
Cayenne.run();
// Wait a few seconds between measurements.
delay(1500);
// Reading temperature or humidity takes about 250 milliseconds!
// Sensor readings may also be up to 2 seconds 'old' (its a very slow sensor)
float h = dht.readHumidity();
// Read temperature as Celsius (the default)
float t = dht.readTemperature();
// Read temperature as Fahrenheit (isFahrenheit = true)
float f = dht.readTemperature(true);
// Check if any reads failed and exit early (to try again).
if (isnan(h) || isnan(t) || isnan(f)) {
Serial.println("Failed to read from DHT sensor!");
return;
}
// Compute heat index in Fahrenheit (the default)
float hif = dht.computeHeatIndex(f, h);
// Compute heat index in Celsius (isFahreheit = false)
float hic = dht.computeHeatIndex(t, h, false);
Serial.print("Humidity: ");
Serial.print(h);
Serial.print(" %\t");
Serial.print("Temperature: ");
Serial.print(t);
Serial.print(" *C ");
Serial.print(f);
Serial.print(" *F\t");
Serial.print("Heat index: ");
Serial.print(hic);
Serial.print(" *C ");
Serial.print(hif);
Serial.println(" *F");
}
// These functions are called when the Cayenne widget requests data for the Virtual Pin.
CAYENNE_OUT(V0)
{
Cayenne.virtualWrite(V0, dht.readTemperature(true));
}
CAYENNE_OUT(V1)
{
Cayenne.virtualWrite(V1, dht.readHumidity());
}
CAYENNE_OUT(V2)
{
Cayenne.virtualWrite(V2, dht.readTemperature());

}
CAYENNE_OUT(V4)
