From what I have seen on the iPod, no 'automatic reconnect to network if Internet not available' is likely true too.

Even though the devices had lost connection over night, the SimpleAP network still showed up in the network list. But neither device could connect.

Have other users been successful using the ESP as an Access Point, that can stay active for extended periods of time?

Thanks Again,
Greg

Here is the printout of my test with your code:
Initialization, 1x web access, sys printout:

After some time I tried to access the web page with PC:

I don't know why I get "Page: Not Found" after a "Page: Root, Heap: xxxxx, UpTime: xxxxxxxxx" in case I access the web page with Android.

The heap hasn't dropped under 35k on my test. I'd say you should update to SDK 1.3.0 or even 1.4 if it is already avalible for Arduino platform.

Thank you for taking the time to look into this, I do appreciate it!
What staging version did you use, and is it 'clean' or have you made other patches?

Thank you,
Greg

- Sun Sep 20, 2015 10:38 pm #29541 I am using an AP for GPS broadcasts over UDP and for the last 108 hours it has been rock stable with 2 PC clients.... both or either. Transmission is every second.

Obviously HTTP over TCP is significantly different, but the AP underpinnings should be common.
