【问题描述】：

我正在尝试将 Arduino UNO WiFi rev 2 与 AWS IoT 连接。目前，我只想每 1000 毫秒发送一个随机数。

#include <WiFi.h>
#include <AWS_IOT.h>

#define WIFI_SSID "_____" // SSID of your WIFI
#define WIFI_PASSWD "_____" //your wifi password

#define CLIENT_ID "Tester"// thing unique ID, this id should be unique among all things associated with your AWS account.
#define MQTT_TOPIC "$aws/things/IOT_test/shadow/update" //topic for the MQTT data
#define AWS_HOST "______________________" // your host for uploading data to AWS,

AWS_IOT aws;

void setup(){
  Serial.begin(9600);
  Serial.println("Initializing thing for AWS");

  Serial.print("Initializing WIFI: Connecting to: ");
  Serial.println(WIFI_SSID);
  WiFi.begin(WIFI_SSID, WIFI_PASSWD);
  Serial.print("  ");
  while(WiFi.status() != WL_CONNECTED){
    Serial.print(".");
    delay(500);
  }
  Serial.println("\n  Connected.\n  Done");

  Serial.print("\n  Initializing program...");

  Serial.println("\n  Initializing connetction to AWS....");
  if(aws.connect(AWS_HOST, CLIENT_ID) == 0){ // connects to host and returns 0 upon success
    Serial.println("  Connected to AWS\n  Done.");
  }
  else {
    Serial.println("  Connection failed!\n check for MQTT problems");
  }
  Serial.println("  Done.\n");
}

void loop(){
  // read temperature and humidity
  float number = random(1, 50);

    //create string payload for publishing
    String random_number = "Random number: ";
    random_number += String(number);
    random_number += " %";

    char payload[25];
    random_number.toCharArray(payload, 25);

    Serial.println("Publishing:- ");
    Serial.println(payload);
     if(aws.publish(MQTT_TOPIC, payload) == 0){// publishes payload and returns 0 upon success
      Serial.println("Success\n");
    }
    else{
      Serial.println("Failed!\n");
    }
  }

  delay(1000);
}

我正在关注tutorial for the NodeMCU-ESP32。

编译代码后，出现以下错误：

In file included from /Users/jesuschueca/Documents/Arduino/libraries/AWS_IOT/src/network_interface.h:35:0,
                 from /Users/jesuschueca/Documents/Arduino/libraries/AWS_IOT/src/aws_iot_mqtt_client.h:57,

 #include "mbedtls/config.h"
          ^~~~~~~~~~~~~~~~~~

Error compilando para la tarjeta Arduino Uno WiFi Rev2.

知道我可能做错了什么，或者我所遵循的教程不兼容吗？

谢谢。

【问题讨论】：

你为 Uno WiFi 上的 esp32 Nina 模块写草图？主 MCU 上的 WiFiNINA 库 应与板载 esp32 模块中的 Arduino nina 固件一起使用。
好吧，我应该把它改成#include ，对吗？
我改了，问题依旧。

【解决方案1】：

问题似乎与mbedtls 3.0.0有关。

在 2.27.0 下，包含目录下存在 mbedtls/config.h，但在 3.0.0 下则没有。

因此，我无法使用 mbedtls 3.0.0 编译 curl - 但我可以使用 mbedtls 2.27.0 编译 curl。

当您切换到 mbedtls 2.27.0 时，也许您的问题已解决。
