我正在尝试将测试值发送到AWS IOT Shadows,但是当我将其上传到设备时,它始终显示“无法设置SSL连接尝试发送数据”。请帮助我将此值发送给AWS IOT Shaodws!我试图将ARN更改为HTTPS端点ARN ..,并不断收到此错误消息。

#include <ESP8266WiFi.h>
#include <AmazonIOTClient.h>
#include <ESP8266AWSImplementations.h>

Esp8266HttpClient httpClient;
Esp8266DateTimeProvider dateTimeProvider;

AmazonIOTClient iotClient;
ActionError actionError;

const char* ssid = "xxx";
const char* password = "xxx";

void initWLAN()
{
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED)
  {
    delay(500);
  }
}

void initAWS()
{
  iotClient.setAWSRegion("ap-southeast-2");
  iotClient.setAWSEndpoint("amazonaws.com");
  iotClient.setAWSDomain("arn:aws:iot:ap-southeast-2:489747887701:thing/IoTTestDevice");
  iotClient.setAWSPath("/things/IoTTestDevice/shadow");
  iotClient.setAWSKeyID("the-id");
  iotClient.setAWSSecretKey("the-secret-key");
  iotClient.setHttpClient(&httpClient);
  iotClient.setDateTimeProvider(&dateTimeProvider);
}

void setup() {
  Serial.begin(115200);
  delay(10);
  Serial.println("begin");
  initWLAN();
  Serial.println("wlan initialized");
  initAWS();
  Serial.println("iot initialized");
}

void loop()
{
  char shadow[100];
  strcpy(shadow, "{\"state\":{\"reported\":{\"test_value1\":123, \"test_value2\":234}}}");

  Serial.println("Trying to send data");
  Serial.print(shadow);

  char* result = iotClient.update_shadow(shadow, actionError);
  Serial.print(result);

  delay(10000);
}

继续收到此错误消息。

请帮助我! 谢谢

setAWSDomain()需要API端点,而不是ARN。

Here is an example

要找到API终结点,请通过转到IoT > Manage > Things > ThingName > Interact在控制台中选择设备,然后找到HTTPS终结点。

或者,您可以从AWS CLI使用describe-endpoint命令。

如上所述,以下行需要使用您的端点进行更新:

From:
iotClient.setAWSDomain("arn:aws:iot:ap-southeast-2:489747887701:thing/IoTTestDevice");

To:
iotClient.setAWSDomain("axxxxxxxxxxxxz-ats.iot.ap-southeast-2.amazonaws.com");

即使解决了这个问题并假设您的esp8266开发板版本> 2.3.0和<2.6.0,您仍然可能会遇到相同的问题:-(

FWIW,esp8266 2.3.0开发板版本将连接到AWS iot,但是应用崩溃会导致另一个问题(参考:https://github.com/esp8266/Arduino/issues/4811)。我还没有找到解决方案……其他人有没有成功?
