Hi all,

"<!DOCTYPE html>"
"<html>"
"<body>"
"<form action=\"/cf\" method=\"post\" enctype=\"multipart/form-data\">"
    "Select image to upload:"
    "<input type=\"file\" name=\"fileToUpload\" id=\"fileToUpload\">"
    "<input type=\"submit\" value=\"Upload Image\" name=\"submit\">"

I upload bin file from webserver but dont know how to recieve it and use for ota update.

Yes, but I want upload bin file by selecting it from system using webserver browse selection..
And as I upload it from webserver, the bin file should be uploaded to esp32 and used for ota.
So that I have to pass that file to ota write.

Can you just get your web server to return a filename or URL to file on server? Then use 4 lines of code to do the OTA. I have a linux box running Apache that I OTA from all the time.
