Colleagues,
Still fighting….after another flashing attemps, I think I am moving(slowly…) . Now the ESP does not reboot and pop up as AP (SSID = OS_16ACD2) with 192.168.4.1, so I was able to connect and got the attached screen from opensprinkler(wifi config). To input SSID and pass , which I did and after that It register to my wifi, but can not get any response from the browser.
Any idea?
