- Tue Jan 13, 2015 4:57 pm #7230 Dir: I tried your sketch out - I can see the ESP request a IP address from my DHCP server but do not see any responses back from the ESP:

Code: Select allDEBUG: Running Setup
ExecCmd:AT+RST
>><<
ExecCmd:AT
>><<
ExecCmd:AT+CWMODE=1
>><<
ExecCmd:AT+CWJAP="xxx","xxx"
>><<
ExecCmd:AT+CIPMUX=1
>><<
ExecCmd:AT+CIPSERVER=1,80
>><<
ExecCmd:AT+CIFSR
>><<
DEBUG: Setup complete

If I run a simple sketch like this:

Code: Select all#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11); // RX, TX

void setup() 
{
  // Open serial communications and wait for port to open:
  Serial.begin(9600);
  mySerial.begin(9600);
  mySerial.println("AT");
}

void loop() // run over and over
{
  if (mySerial.available())
    Serial.write(mySerial.read());

}

I can see the return code OK.

Any ideas?

Any ideas?

Can you paste some of what you're getting in the serial monitor? Might help us better figure out what's going on.

Thanks, it works a treat with my Arduino nano and ESP 05 - Sometimes it the nano needs a reset when the whole circuit is powered up but I think I just need to tinker with the timings of the AT commands.

Thanks again
