This modification performs a ping request to the local IP address every 60 seconds. By this procedure the web server remains accessible in some problematic WLAN environments.
The modification works with static or DHCP IP address configuration
Story:
Unfortunately, with all ESP projects where a web server or other network services are running, I have the problem that after some time the web server is no longer accessible. Now I found out that the connection is at least reestablished when a ping request is executed by the device.
With this modification, in the worst case, the network functions are not available for 60 seconds until the next ping request.
Copy and replace the file usermod.cpp in wled00 directory.
