I'm getting out of ideas so I'd appreciate if anyone can give me some pointers -

on 2.0.0 stable with

Code: Select allESP8266WebServer httpServer = ESP8266WebServer(80);
WiFi.mode( WIFI_AP );
loop() { httpServer.handleClient(); }


ESP's webserver is accessible for about 5-10 minutes, after that no response. Other ESP code parts itself happily work the whole time. My connection path is ESP <-> ZTE WiFi router <-> PC.

Sometimes I do get following -

Code: Select allstate: 5 -> 2 (6c0)
rm 0
pm close 7 0 0/1127576013
reconnect
state: 2 -> 0 (0)
f -180, scandone
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 5 (10)
add 0
aid 2
pm open phy_2,type:2 0 0

but not always. What code I can use to prevent this problem ? Bigger hammer ?

This problem is only in STA mode, if I change ESP to AP mode webserver works with no problems for ages.

TIA,

finally some good news, with the latest versions of almost all package parts it works stable as rock. Not even a single reconnect/drop or anything similar.

Important parts are 1.5 SDK and reworked ESPWiFi Class, and a bit less important is 1.6.7 arduino for OTA.

In short - Arduino IDE 1.6.7 + todays git = WiFi STA connection stable !
(ty @Links2004 for awesome work)
