wifi_station_scan failing everytime it runs. SDK 1.3.0
Posted: Sun Aug 30, 2015 1:57 pmHi everybody.
I've been playing with the SDK lately, i can connect to APs and blink LEDs and so, but when i try to scan for near APs, the status code always says FAIL.
Here is my code i've been 3 days changing up things, but nothing works. Hope anyone could hint something
Thanks!!
