Hi, in this project I am trying to use the NodeMCU Amica development board to carry out laboratory tests.
This is the photo of the module I’m testing.
As I already said, I compile and load the sketch without error, one messages appear on the serial monitor “[239] Connecting to CLEMENTE.NET”
and, not happens nothing, The WiFi module LED remains off.
Is there anyone who has already solved this problem and can give me a hand?
This is the sketch I am trying

This example runs directly on ESP8266 chip.
Note: This requires ESP8266 support package:
Please be sure to select the right ESP8266 module
in the Tools → Board menu!Change WiFi ssid, pass, and Blynk auth token to run
Feel free to apply it to any other example. It’s simple!
