Recently I got a whole new ESP8266 wifi module and try to build an automation home system using wifi shield control Arduino action. I did some research from using Andriod apps until the software control using ESP8266.
I tried only upload blank sketch to do Arduino and perform AT communication directly using Serial COM port communication, its work perfectly.
Then I tried using code, with Softwareserial.h and using mySerial.write to the Wifi module, it seems that no response from ESP8266 after the program write to the RX/TX pin direct to the ESP8266.
ESP8266 connection: 1. Vcc - 3.3v from Arduino itself. - I read some thread that asked about the similar problem and tried with different 3.3v source but it doesn't seem working.
- Channel_PD is tied with Vcc.
Problem now is, ESP8266 is working with empty sketch but couldn't setup a server automatically using only Arduino sketch that executed for Server setup.
I tried to dig more research but doesn't really got the same condition as what I dealing here.
