Web App not working on Android

[simisv]

Hi
I tested for first time WebApp and is a great feature . When I run the page from Chrome on my windows 10 laptop , communication with my esp32 module is ok . When I run it from my android 13.1 phone there is no communication towards esp32 .
How can I solve the problem on my phone ?
Thank you

Hi

With only the html there isn't much to go on, but it looks like your target is on your local network (I might be wrong as I am looking at this on my phone)? If so is the phone on the same network at target or is it connected to the cellular network?

Hi

Have you tried other browsers? If possible try Chrome / FireFox / DuckDuck etc.

WebApp I can open it with only some browsers : Chrome , Edge ,Samsung Internet Browser ,Opera , Web Browser & Web Explorer ,Web Browser, and none of these are sending data .

Hi

Can you ping your target from your phone? You may need a 3rd party tool set to do that such as "ping tool" or the like.

That would prove your target is reachable and eliminates network concerns,

It documents some browser issues.

Hi
Ping results are 21.6ms min to max 386ms and 144.46ms average with 0 packet loss .
No positive results from web browser Chrome can't even read the last location of the file , and I copied the file inside Download folder .

Hi

On my phone just now, so no access to my files. Do you mean Chrome can't find your file? If so I had a similar issue a while back so used File Manager + (android) to move the file to where Chrome could look (downloads I think offhand).

From memory, I believe Chrome is isolated from a lot of locations on an Android phone for security (it is kind-of sand-boxed). That means it cannot read or write to local files. Perhaps this accounts for the problems you are seeing.
