ESP8266 Community Forum

Hi there,

I've connected my Arduino Uno to ESP8266 wifi module directly except some voltage division resistors. I'm able to read AT -> OK and AT+GMR -> Version stuff. However, whenever I try to search WiFi networks nearby (AT+CWLAP) it returns ERROR.

I'm also able to change baud value, everything works just fine.

What should I do?

Thanks in advance.

You need to do a AT+CWMODE before to get the ESP in STA or STA+AP, otherwise it is normal to get the ERROR.
