Esp8266 no response in serial monitor via arduino nano
Posted: Fri Dec 02, 2016 1:26 amI have connected my esp8266 to my arduino nano via various guides i have seen online
Esp rx > arduino rx
Esp tx > arduino tx
Esp 3.3V > arduino 3v3
Dh_cp > arduino 3v3
Esp gnd > arduino cms
I have tried using resistor divider on tx as well
In case it was a firmware problem, after a lot of tries, i flashed a firmware from esp site (latest esp8266 nonos ask non boot version) , yet it was no help
I get no response or anything printed on the serial monitor screen, no feedback or anything, when I send AT, it doesn't appear on in the serial monitor screen either.
My arduino is connected to USB and 12v input at VIN
The esp gets red light on constantly, blue turns on at start and then stops, on arduino rx red light stays on as well (when I have dh_cp connected)
