Update AsyncUpdate.ino
I saw a little bug: after upload, it did not show the message "Please wait while the device reboots", so I implemented another way to get that and redirect to main page after a seconds.
Best regards!
EDIT 1: and thanks you very much, I did not saw the code for WebUpdate simpliest as you did! =) EDIT 2: I used an ESP8266
Thank you @castillo92 for your simple solution about this response! This works for me. But, i called the Response on the Webserver "Upload started!...." because it is actually not "... completed" on this line at all! It still can causes an failure! Maybe an progress bar or something like this would be great to give the user a feedback that the OTA Update is working and not hanging up or somthing goes wrong...
kindly regards!
