Heltec WIFI lora32 V3 failed to connect to Arduino IOT

#1

I have a project to connect Wi-Fi Lora 32 (v3) as a receiver to Arduino Cloud, after several trial I finally succeeded to make the module online, but I cannot run any code in the skitch, I need to save the received RSSI and SNR to the cloud
here’s the code wich is already run using Arduino IDE:
#include <heltec.h>

/* Heltec Automation Receive communication test example
*

  • Function:
    1. Receive the same frequency band lora signal program
  • Description:
  • HelTec AutoMation, Chengdu, China
  • www.heltec.org
  • this project also realess in GitHub:
