I want to know if the network to which esp connected has internet connectivity or not. How can I send a ping request using esp32?

  • We expect you to have done some basic research before asking a question (and explain why what you've found doesn't work)

    a quick google search of esp32 ping provides plenty of results. :-)

    use the http client to fetch a small file/page from the internet, one that you expect will always be up.

If you want to test internet connectivity the best way is to request http://google.com. If your device is connected to internet, you would get 301 as response code.

You can ping some address and see if it is reachable. You can use this library for the same.

  • Are you sure? That just means you are connected to an access point, not that you have internet access.

  • This is now basically a link only answer which will become useless if the link breaks.
