Hi everyone, I am using a NodeMCU 1.0 v3 and I am trying the example sketch (wifiscan) but it just doesn't pick up any AP in the house. My phone and laptops etc are able to pick up the APs though.

Other sketches upload and work fine but the wifi aspect of it doesn't work. I even got an LCD sketch to work properly but it isn't able to find any access points or even join any access points. I have been trying to get it to work for hours now.

I first tried using the latest Arduino IDE (1.6.12), then I uninstalled and tried using 1.6.1 but no luck. My upload settings are NodeMCU 1.0 (ESP-12E module), 80Mhz, 115200, 4M (3M SPIFFS).

I flashed it to At firmware, nodemcu and arduino.. all commands work on each of the different firmwares except wifi-related commands.

Example: blink sketch works in arduino ide, but no wifi sketches (uploads fine though).

Please help

Friend, I faced the same problem with you, when I google search on it only your post shown up. I just solved the WiFI detect problem ( by using the" WiFIScan" example), the solution is get by this video https://www.youtube.com/watch?v=z07zjfO ... e=youtu.be.

After I flashed the AT firmware, my NodeMCU 1.0 can successful detect the SSID.

AT firmware ( I using the ai-thinker-0.9.5.2-115200.bin)

For the flashing baudrate, the video is using 576000, but I am using 115200, I think the advanced set up might not be a matter.

Hope its may help you.

Thanks RayDivine, but I am using arduinoIDE so how would installing AT firmware help? I am confused.
