I just install ESP-IDF with Eclipse and I compiled template project and upload it to ESP32. It runs on ESP and terminal output changes then i change printf strings in main.c.
I changed SSID and password for connect to my home AP but ESP not connects to my AP.
In terminal i take:

Also i try this WiFi scan example (https://github.com/VALERE91/ESP32_WifiScan) and it works fine.
