can not connect to a specific WiFi access point

[alexweefs]

I have a problem that ESP8266 could not be connected to certain WiFi access point.

(Using non-OS SDK V2.0.0)

As a result of examination, ESP8266 seems to be rejected with non-support about Short Slot Time option.

[Q1] Is it correct in my understanding as above?

[Q2] Is there a way to support Short Slot Time option?

The SDK you used seems to be a very old version? Maybe you can have a try with latest SDK? https://github.com/espressif/ESP8266_RT ... ng_started
