Maybe post the sketch you are using? Also, a schematic and/or a photo of your wiring would also be useful.

Ok, here it goes...
Details:
- I am using an FTDI / USB B75937 chip. (I found some problems with this converter here
http://forum.arduino.cc/index.php?topic=136267.0- ESP8266 v12.
- Sketch can be uploaded properly (blue led blinks), and the Arduino IDE message returns UPLOADED.
- Run mode seems to work (I have tested the blink example).
- I can see the chip with a WIFI Scanner program, and I can make ping.
However:
- Webserver doesn´t work (I write on my browser the IP of the ESP8266 but nothing appears).
- No printed messages with the serial.print of the Arduino IDE.
Electrical details:
1. RST connected to RESET of the FTDI / USB converter.
2. 3.3V connected to GPIO2 / VCC / CHPD / GPIO0 (just for nomal mode)
3. GND to GND / GPIO0 (just for flash) / GPIO15
4. TXD to RXD / RXD to TXD.
5. Furthermore, I am using two 1.5V batteries (I read that the current consumption of these modules is too high for Wifi to be supplied just for the USB port)
6. led connected to gpio13.
Any ideas? Should I change the batteries?
Thanks
