I've been working on integrating the HTTPUpdateServer into my esp arduino based project, and I've hit a snag. I get the following error during compilation:

no matching function for call to 'ESP8266HTTPUpdateServer::setup(WiFiServer*)'

The difference between my code and the example sketch is that I am using "WiFiServer" library to create a web server and handle http requests and it looks like the ESP8266WebServer library, which is used in the example, is different.

My question is, does anyone have a recommendation on the best path forward on this? Should I try to convert my code from using WiFi to use WebServer or should I do something else. I wasn't able to look into the libraries themselves yet, but could anyone comment on the actual differences?

Thanks for any thoughts!

For my application, running the webserver on an ephemeral port made a lot of sense. Therefore, I just set the upload server to run on a high port number and kept the original HTTP related code to run on port 80. This was great for me because I could keep two separate objects running and have separate chunks of code need to be rewritten or libraries extended. MDNS will still work for both port numbers as well, I believe as long as mdns.addService is used to add the port number.. Hope this helps someone else!

wow.. thanks for this info! I was wondering about something like this in order to work around some issues on a project I have in mind

For example, HTTP on port 80 along with Telnet on 23.
