#37462 Hi,

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.
