ESP8266 Community Forum

- Sun Feb 24, 2019 3:23 pm #80781 I have a server running on an 8266 that sends a page with some controls on it for various IO.

The first couple times I load up the page everything works.

After a few the AP mode will stop working. It stops broadcasting, and calls to begin return false.

Am I running into some sort of buffer I need to flush? Could it be that I am changing global vars in the handler function?

What you are trying to archive is the same as in the library example "WiFiaccesspoint":

This example is working absolutely well and it won't stop or block or anything. So, I'm afraid there must be a little "Oops" in your code. Maybe you could post your code...
