Ok, I ended up solving this rookie mistake.
Had to do with my local implementation of the source files with the arduino ide that I am using.
I found out the real directory that was used, included the file properly and it worked.
Ping from ESP32
Re: Ping from ESP32
I'm trying to use ping API of ESP8266_RTOS_SDK but there is a problem with ping_init() function, i'm including two libs ping.h and esp_ping.h. The functions of esp_ping are working fine, but the linker do not recognize ping_init of ping.h calling: " undefined reference to `ping_init' " when i try to make the project.
Someone could help me?

Re: Ping from ESP32
I am also seeing the undefined reference to `ping_init' " issue.

Re: Ping from ESP32
Hi,
try to include "ping/ping.h".
The ping.h path is not in the compiler paths configuration.

Re: Ping from ESP32
Finally I succeeded in pinging using ESP-IDE.
It is published here.

Re: Ping from ESP32
Frustrating how esp-idf examples are so overcomplicated. Examples provided in this thread from years ago do not work, as ping_init() is deprecated. Here's a nice simple method to ping 8.8.8.8 with latest IDF, and utilizing the overcomplicated example from the idf documentation here: https://docs.espressif.com/projects/esp ... _echo.html

Re: Ping from ESP32
Hi can u provide a code for sending ping on all interfaces?
I tried adding interface index but that gives be error on Ping handle being NUll
