which device are you using and can you share the code. Any specific reason to use the manual code?

#3

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?

#4

i guess he meant this https://github.com/myDevicesIoT/Cayenne-MQTT-Arduino/tree/master/examples/Connections/ManualConnection

#5

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.

#7

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.

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.

#10

it is affected? because when i am doing directly example Ethernet w5100 it run smoothly.

#11

this pins are used for communication between uno and ethernet shield, so using them causes to disconnect from internet.
