I have got the ESP32DEMO working with the help of folks here. Thank You.

I followed the flow in ../tutorials/esp32 but used the example for wpa2_enterprise.

There is a compiler error that I do not understand:

Severity    Code    Description    Project    File    Line    Suppression State
Error        undefined reference to `emac_send_pause_zero_frame_enable’    wpa2    C:\Users\Donald\Documents\visualStudio2017\wpa2\wpa2\VisualGDB\Debug\emac_main.o    1

Severity    Code    Description    Project    File    Line    Suppression State
Error        undefined reference to `emac_send_pause_zero_frame_enable’    wpa2    C:\SysGCC\esp32\esp32-bsp\esp-idf\components\ethernet\emac_main.c    600

Severity    Code    Description    Project    File    Line    Suppression State
Error        ld returned 1 exit status    wpa2    C:\Users\Donald\Documents\visualStudio2017\wpa2\wpa2\collect2    1

The editor can find the inline function call but the compiler can not.

Can someone help a newbe.

Thank You
