ESP8266 AP mode won't let reconnect
Posted: Sat Jul 08, 2017 1:52 pmHi guys,
I have a problem with androids phones: after one connection they wont reconnect (forbidden acces). I use many of solutions as: another channel, make STA then AP, newer version of IDE 1.8.2 etc, same problem on various boards like nodeMCU, wemosD1, standalone ESP8266.
ESP boards version 2.3.0 in IDE.
This is my code:
