Re: WPS connectivity problem

Some of my WPS problems appear to be related to insufficient free RAM. When I moved some large constant strings into flash (requires more than just defining them as const with ESP8266 toolchain) to free up RAM, some of my WPS problems disappeared. However, I still cannot get the ESP8266 to connect t...

Re: WPS (Wi-Fi Protected Setup) in SDK

Part of the problem turns out to be free RAM. The 802.11ac WPS process requires considerably more free RAM than for 802.11a/b/g/n. My application had some large statically allocated tables. When I changed these to be dynamically allocated after WPS completed, it worked properly for some access point...

Re: WPS connectivity problem

In case it provides more clues, the WPS function seems to work reliably with older 802.11n access points (Trendnet TEW-652, Belkin N300), but fails reliably with 802.11ac access points (AT&T/Pace 5268AC and Asus TM-AC1900). I am using Arduino/EPS8266 core version 2.3.0 which uses SDK version: 1....

Re: WPS (Wi-Fi Protected Setup) in SDK

I have been able to establish connections via WPS successfully to several types of 802.11n access points but connections fail to 802.11ac access points; has anyone else had this problem?
