see attached pics for this pins and serial monitor screenshots.
i just got the ESP8266 module from here:
http://www.ebay.com/itm/ESP8266-Serial-WIFI-Wireless-Transceiver-Module-Send-Receive-LWIP-AP-STA-arduino-/181583935325?pt=LH_DefaultDomain_3&hash=item2a473ef75dI wired it up:
RX to arduino's pin 3
TX to arduino's pin 2
VCC + CH_PD to 3.3v input (not related to arduino)
GND (black) to ground
Using the following arduino code:
--------
#include <SoftwareSerial.h>
SoftwareSerial mySerial(2,3);
void setup()
{
mySerial.begin(9600);
Serial.begin(9600);
}
void loop()
{
if (mySerial.available())
Serial.write(mySerial.read());
if (Serial.available())
mySerial.write(Serial.read());
}
--------
The wifi red led is working, and I'm trying to send commands to it using the serial monitor (it is set to 9600 baud and carriage return mode).
When I send the command, I can see the WIFI's blue light flickering (I'm sending AT+GMR to display its firmware version) - seems that it is getting the transmission, but the serial monitor displays strange characters and not the expected result (happens for any AT command I send).
I want to test it with AT commands before I code an arduino app for it.
What am I missing here?
