error: no matching function for call to 'ESP8266::ESP8266(SoftwareSerial&)'

[DeanZilla]

Hi,

I'm a noob, so forgive me if this isn't the right place to post.

I have an UNO and are using SoftwareSerial to connect to my ESP8266.

When I compile, I get the following error "error: no matching function for call to 'ESP8266::ESP8266(SoftwareSerial&)'" when it reaches the line below "ESP8266 wifi(mySerial);"

Below is a snippet of my code.

-----Snip-----

include "ESP8266.h"

define SSID "farm"

define PASSWORD "sheep"

define USER_SEL_VERSION VERSION_18

define ESP8266_USE_SOFTWARE_SERIAL

include

SoftwareSerial mySerial(2, 3); // RX, TX

ESP8266 wifi(mySerial);

void setup(void) ----Snip-----

Regards

Dean

Check again the documentation: https://github.com/itead/ITEADLIB_Arduino_WeeESP8266#using-softwareserial Did you uncomment the lines it says?

https://github.com/itead/ITEADLIB_Arduino_WeeESP8266#uno In your code(at least what you posted) you have the following:

include

SoftwareSerial mySerial(2, 3); // RX, TX

Notice that you are missing the "included library" in the statement #include It should be

include

SoftwareSerial mySerial(3, 2); /* RX:D3, TX:D2 */

I was having the same problem.

The readme says I should uncomment this in ESP8266.h

//#define ESP8266_USE_SOFTWARE_SERIAL

but the command is not even in ESP8266.h.

Instead I had to add it.

It says to change this line:

#define SERIAL_BUFFER_SIZE 64

but instead I only see references to:

#define SERIAL_TX_BUFFER_SIZE 64
#define SERIAL_RX_BUFFER_SIZE 64

The top of my file defined for arduino uno is:

#include "ESP8266.h"
#include <SoftwareSerial.h>

SoftwareSerial mySerial(3, 2); /* RX:D3, TX:D2 */
ESP8266 wifi(mySerial);

#define SSID        "myssid"
#define PASSWORD    "mypasswd"
#define HOST_NAME   "node-red"
#define HOST_PORT   (4894)

No joy... It still does not work.

I would like to make it work with Arduino Micro.

Has been updated. Thank you for your questions！

@TinajaLabs We have used the 0.18 version of the firmware, the latest version of the library, switch to the 0.18 version of the UNO test software, serial port, has been running. You can test it, thank you for your question!
