- Tue Nov 17, 2015 9:08 pm #34373 I finally got it working now. I like to share the followings.

1) if your esp8266 is fluctuating check your power source to make sure your 3.3v is regulated correctly and have enough current to support the module.
2) in my case, the module kept resetting itself. I solved this problem by adding few capacitors to the power source to stabling it.
3) it seems to function better after i run the AT+RESTORE
