Error ThingerWiFi.h

1

Hi there,

I’m trying to test one of your examples “ESP8266” with DHT22 and this is my code:

#include <SPI.h>
#include <ESP8266wifi.h>
#include <ThingerWifi.h>
#include "DHT.h"

#define USERNAME "your_user_name"
#define DEVICE_ID "your_device_id"
#define DEVICE_CREDENTIAL "your_device_credential"

#define SSID "Wi-Fi Waves"
#define SSID_PASSWORD "f3rr3ir4"

#define DHTPIN 22 //pin no arduino
#define DHTTYPE DHT22 

ThingerWifi thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL);

DHT dht(DHTPIN, DHTTYPE);

void setup() {


  thing.add_wifi(SSID, SSID_PASSWORD);


   thing["Temperatura"] >> [](pson& out){out = dht.readTemperature();};
   thing["Humidade"] >> [](pson& out){out = dht.readHumidity();};

}

void loop() {
  thing.handle();
}

but gives me this error:

Can anyone help me pls.

Some thoughts:

  • You are trying to compile a code for the ESP8266, but you have selected the Arduino Mega as board (regarding the compiler output). If you have an ESP8266, you must select it in the compiler to have their libraries available.
  • Be careful with the includes, not sure if your OS is case sensitive, but fix the include #include <ESP8266wifi.h> to #include <ESP8266WiFi.h>

Can you give me more details about your setup? board, etc?

Hi there,

i just changed to ESP8266 Generic and the error now is

esp8266: Unknown package.

Error compiling

I also changed the include (it’s case sensitive).

I send you an image with the setup ( board is a Mega 2560).

I think that the Arduino 1.6.7 is not compatible with the ESP8266 library. Try to switch your Arduino version to version 1.6.5, or as recently stated in the Github page, now it is supported in Arduino 1.6.8. Hope this help!
