Hi im using an arduino Mega with an esp8266 chip (RX/TX) that connects to Cayenne IOT Dahsboard..
The sensor works perfectly without me using software serial.. but as soon as i add the cayenne credentials etc.. the sensor never gets past the 5 min warming up stage..
Please advise.. im fairly new to this and no idea why it wont work..
heres my code..
#include <SoftwareSerial.h>
//#define CAYENNE_DEBUG // Uncomment to show debug messages
#define CAYENNE_PRINT Serial // Comment this out to disable prints and save space
SoftwareSerial ESPserial(19, 18); // RX | TXAT+CIOBAUD=9600
#include <CayenneMQTTESP8266Shield.h>
// ---------- WiFi network info -----------
char ssid[] = "VM2588954-2G";
char wifiPassword[] = "v2yhHrkFybwv";
char username[] = "0dcf1300-a65f-11ea-a67f-15e30d90bbf4";

char clientID[] = "a19cece0-9967-11ec-8c44-371df593ba58";
// Set ESP8266 Serial object. In this example we use the Serial1 hardware serial which is available on boards like the Arduino Mega.
