ESP8266 wifi(mySerial);

I'm using an arduino nano v3 and I got this error

ConnectWiFi:28: error: no matching function for call to ‘ESP8266::ESP8266(SoftwareSerial&)’ /home/ricardo/.AIDE/arduino/libraries/WeeESP8266-master/ESP8266.h:37: note: candidates are: ESP8266::ESP8266(HardwareSerial&) /home/ricardo/.AIDE/arduino/libraries/WeeESP8266-master/ESP8266.h:29: note: ESP8266::ESP8266(const ESP8266&)

If I just write

ESP8266 wifi(Serial);

Apparently my problem has gone but I can't connect the ESP with my AP

Any idea?

Does this happen every time you try? I've found with my esp01 it locks up from time to time. I found that I if I cycle power to the esp it can connect again. I'm experiment with using a transistor inline with the 3v3 power on the esp board and then allowing for cycling the power from my arduino. If/when I figure it out I'll try and add a method into the library to handle this process automatically.

No this happen always, is not ESP problem, is a library problem. why I think this?. In the readme says if a have an UNO (nano is basically the same), add this

include

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

If I change this in the original files I have the problem just compiling

The original files come with

ESP8266 wifi(Serial1);//This not work neither

But if I change just this line a write all compile good without need SoftwareSerial library ESP8266 wifi(Serial);

Hi, you need to modify the ESP8266.h file first. in ESP8266.h uncomment #define ESP8266_USE_SOFTWARE_SERIAL

in the Sketch include the file like this:

include "ESP8266.h"

include

SoftwareSerial Serial1(3, 2); /* RX:D3, TX:D2 */ ESP8266 wifi(Serial1);

PS: I use level shifters from 5V to 3.3V as my Arduino ProMINI clone is running at 5V, remember that ESP8266 is ONLY 3.3V tolerant !

aniston's answer is correct! Thank you !
