Hello,

I am beginner in Arduino IoT and my problem is : I follow all the steps of teh tuto "Connecting ESP32 to Arduino Cloud IoT and I get on the Monitor :

Arduino IoT Cloud - configuration info \*\*\*\*\*  
Device ID: cad31529-e6b8-44d9-bf52-a88ca7e9ae04  
MQTT Broker: mqtts-up.iot.arduino.cc:8884  
WiFi.status(): 255  
Connection to "SFR\_7268" failed  
Retrying in "4000" milliseconds  
Connection to "SFR\_7268" failed  
Retrying in "4000" milliseconds

I use ESP32 DevKitC (ESP32-WROOM-32D) that I declare as ESP32 Dev Module in Device list.

I have made sevral trials, all with the same result.

What is going wrong ?.

Thanks.

I add : the same kit with an Arduino IDE sketck using Wifi library and the same Wifi parameters (SSID, password) works correctly !.

Seems like the board can't connect to your WiFi network, so not a cloud issue. Can you try with a basic WiFi sketch for ESP32 to check if you're able to connect wth it?

As I added just after my first request : the same kit with an Arduino IDE sketck using Wifi library and the same Wifi parameters (SSID, password) works correctly !.

Thanks for reply.
