Problem with ESP-WROOM-32 and WiFi
Posted: Mon Feb 12, 2018 6:37 pm
Hi, I'm studying ESP-WROOM-32 and I've a problem with all programs that needs of WiFi.
I'm use esp-idf and I tried to upload all examples that needs of wifi (/esp-idf/examples/wifi) and all have the same problem.
If I try to use for example blink or hello_world (/esp-idf/examples/get-started), them works fine.
When I turn on the module after uploaded the program, trough the serial monitor I see these messages recursively:
I don't understand what's the problem 
Can you help me?
Many thanks.
Best regards.
