- Sun Jun 14, 2020 9:12 am #87544 Still a small problem.

The XMLHttpRequest() version works but the fetch version does not.
The ESP receives the command, and returns the answer (Serial print for confirmation) but I dont get an answer by fetch.......

Thanks in advance.

- Sun Jun 14, 2020 8:53 pm #87547 Do you need both versions? XHTTP is the lowest common denominator, whereas fetch isn't supported on IE 11.

If you use the Web Console in your browser, you can see the requests and response to each network call. This will tell you whether the response is coming back to the browser or not.

You can also change the code to log the response object itself and see the detail in the browser console:

Code: Select allfetch("HTTP://192.168.1.80/temperature")
.then(response => {
  console.log(response);
  return response.json();
})
.then(data => {alert('Success:', data[0])});
