ESP-12: Unable to send AT command
Posted: Wed Dec 30, 2015 7:48 amHi,
I am not able to send any AT commands through Arduino Serial Monitor or Putty to ESP-12.
When I connect REST to GND, I see the messages [System Ready, Vendor:www.ai-thinker.com]. But I am not able send any commands.
This is my configuration.
Tx of ESP8266 -> Rx of CP2102
Rx of ESP8266 -> Tx of CP2102
GND of ESP8266 & GND of CP2102 -> GND of LD33V
VCC of ESP8266 -> VOut of LD33V
GPIO15 -> GND
CH_PD -> VCC
GPIO2 and GPIO0 -> Floating
REST -> Initially to ground for 1 sec and then floating.
BaudRate: 9600
Measured voltage: 3.08 v
Measured current: 0.6 amp
Any inputs on this will be much appreciated
Thanks.
