Hello,
I'm trying to setup my ESP8285 to connect to any available Wi-Fi network as described here: https://ubidots.com/blog/connect-your-esp8266-to-any-available-wi-fi-network/
However, whenever I verify the code, I get the below error:
Arduino: 1.8.9 (Windows 10), Board: "Generic ESP8285 Module, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), dtr (aka nodemcu), 26 MHz, 1MB (FS:64KB OTA:~470KB), 2, v2 Lower Memory, Disabled, None, Only Sketch, 115200"
