ESP8266 Network problem please helpp !!!!!
Posted: Mon Feb 26, 2018 7:56 amHi guys I just made my own pcb for esp8266 chip and i picked up all schematics from NodeMcu V1.0 .So Hardware is same as NodeMcu as far as i know ...
So here's the problem my codes works well with NodeMcu But when i upload it to my board every thing works except WiFi .
when i start esp as access point it shows in the wifi list of my phone but i can't connect to it . i think it can't assign ip for my phone
and again when i choose station mode and give it the right ssid and pass to connect my phone's hotspot that is near my board again it recognize all the stations around board but it can't connect to any of them . i've tested this with router too .
So how can i fix this ? I apreciate all of your answers
here is a code for station mode that doesn't work
