which device are you using and can you share the code. Any specific reason to use the manual code?
I have a post here that shows how to use pubsubclient to connect, but from your output that’s not what you are doing. What do you mean by manual connection?
i guess he meant this https://github.com/myDevicesIoT/Cayenne-MQTT-Arduino/tree/master/examples/Connections/ManualConnection
Ah, yes forgot about that one. @teras.olive if you are getting that exact output where it stops mid print then I would suggest checking your power supply, or trying another one.
I am using Arduino Mega2560 with ethernet shield w5100. I need to set static IP and DNS because the company blocks the dynamic IP for security.
share the code you are using.
#define CAYENNE_DEBUG // Uncomment to show debug messages
#define CAYENNE_PRINT Serial // Comment this out to disable prints and save space
#include <CayenneMQTTEthernet.h>
//#include <CayenneMQTTEthernetW5500.h> // Uncomment this and comment out CayenneMQTTEthernet.h to use an Ethernet 2 shield or other Ethernet W5500 shield.
// You will need the Ethernet2 library installed. See the ArduinoEthernetW5500 example sketch for more info.
//#include <CayenneMQTTEthernetW5200.h> // Uncomment this and comment out CayenneMQTTEthernet.h to use an Ethernet W5200 shield.
// You will need the EthernetW5200 library installed. See the ArduinoEthernetW5200 example sketch for more info.
#include <MemoryFree.h>
#include “DHT.h”
// Cayenne authentication info. This should be obtained from the Cayenne Dashboard.
char username = " ";
char password = " ";
char clientID = " ";
// Mac address should be different for each device in your LAN
byte arduino_mac = { 0x00, 0x01, 0xBA, 0xFE, 0xFE, 0xCC };
IPAddress arduino_ip(10, XXX, XXX, XXX);
IPAddress dns_ip(10, XXX, XXX, XXX);
IPAddress gateway_ip(10, XXX, XXX, XXX);
IPAddress subnet_mask(255, XXX, XXX, XXX);
Arduino uses digital pins 10, 11, 12, and 13 (SPI) to communicate with the W5100 on the ethernet shield. These pins cannot be used for general i/o.
it is affected? because when i am doing directly example Ethernet w5100 it run smoothly.
this pins are used for communication between uno and ethernet shield, so using them causes to disconnect from internet.
right i have another question how to make that cayenne sent received data acknowledgement to Arduino?
this cannot be done.
