Don't know if something like an empty module is required for esp8266 to respond to arduino sketch sending AT commands. I had the module working more less fine with arduino, then loaded an sketch on it to try the arduino IDE. It worked fine, but now it doesn't run the arduino sketch that I had tried before and worked more less fine. I am using arduino uno, ide 1.6.1 and supplied external power to arduino. Any ideas on what might be happening? Tried 9600 an 152000 baud speeds without success. Sketch arduino working but resetting was commented here http://forum.arduino.cc/index.php?topic=313683.0

I had the same problem. see here viewtopic.php?f=32&t=2275&start=10#p13674 this will install an AT firmware and get back to a module that works. while you have the AT firmware in there you should run AT+CWMODE=1
to get it out of AP mode as it otherwise sticks - even after loading an aurdrino sketch.
