Dear Sir,


I have an arduino uno r3 and the ESP8266 ESP-12e.

Basically, I want to send 2 numbers from my arduino to my laptop. I haven't reached there yet.
I am trying to see if ESP8266 is working. I am sending AT commands but the ESP8266 is not responding.

I am using the LM1117 to get 3.3 V.

Here is the way that I have my connections:

Arduino ESP8266

Tx Tx

Rx Rx

Gnd Gnd

5V to the input pin of LM1117

The output pin of LM1117 is connected to the Vcc and CHP_EN of ESP8266

The Gnd pin of LM1117 is connected to the Gnd of Arduino and ESP8266


Can you please tell me what is wrong?

 

I had one running some time back but I had it:

TXD to RDX
RXD to TXD
