I've two new Esp8266 ESP01 modules that I've programmed with FTDI232 and Arduino IDE 1.6.5. I've found on internet a sketch to drive a lamp by this module (with aREST and aREST_UI libraries) and I was able to test them with this sketch. All seemed works fine.
The problem is that after the first time I've had a lot of problems. First, during the upload : I've to tried a lot of time before upload without problem (warning: espcomm_send_command: wrong direction/command: 0x01 0x03, expected 0x01 0x04, ). But also after upload nothing works like the first time (no messages on serial monitor etc.).
For the programming I've followed the procedure (GPIO 0 to ground.....) and the following IDE parmeters:
1) Board : generic ESP8266 module
2)Flash Mode QIO (also DIO)
3)Flash freq 80 Mhz (also 40Mhz)
4) Upload serial
5) CPU 80Mhz
6) Flash size 512k
7) Upload speed 115200 (but also others).

thank you in advance for any suggestion and help

Ended up as a faulty usb to uart device - the "espcomm_send_command: wrong direction/command: 0x01 0x03, expected 0x01 0x04," flagged this. If you google it, it's not a common fault.
