Problems with ESP8266 and Arduino for simple connection
Posted: Sun Oct 18, 2015 8:25 amHi everyone,
I'm going to explain my situation. I have the WiFi card ESP8266 ESP-01 with firmware AI-thinker versione 0.9 and I want to install on Arduino this software:
Due to the fact that Arduino can't supply correctly the voltage to the card, I'm using this http://www.miupanel.com/Wi-Fi-Module/ACCESSORIES/-BREADBOARD-ADAPTER and the connection are:
VCC 5 Volt -> +
GND -> -
D3 -> RX
D2 -> TX
When I run the software I face this error:
setup begin
FW Version:
to station err
I've tried different cards, so no one of them are damaged. Why am I facing this problem ? Are there any errors ? Thank you in advance for your support.
