Arduino UNO WiFi Rev 2 未发布到 SSL 连接

Question

我在尝试让我的 UNO WiFi Rev 2 向我的 https azure 服务器发出 POST 请求时遇到问题。 我已经能够使用 MKR1000 使用 WiFi101 库成功地发布到该服务器，所以很奇怪我无法使用 WiFiNINA 库让 UNO 发布。 我已经尝试了两种方法来处理这个 POST 请求，如果有人可以为其中任何一种提供解决方案，我将不胜感激。

我的第一次尝试是基于 WiFININA 库的 HTTPS POST 示例：

This example creates a client object that connects and transfers
data using always SSL.

It is compatible with the methods normally related to plain
connections, like client.connect(host, port).

///////please enter your sensitive data in the Secret tab/arduino_secrets.h
char ssid[] = "secret";        // your network SSID (name)
char pass[] = "secret";    // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0;            // your network key index number (needed only for WEP)

int status = WL_IDLE_STATUS;
// if you don't want to use DNS (and reduce your sketch size)
// use the numeric IP instead of the name for the server:
//IPAddress server(74,125,232,128);  // numeric IP for Google (no DNS)
char server[] = "secret";    // name address for Google (using DNS)

// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
int HTTP_PORT = 443;
String HTTP_METHOD = "POST";
char HOST_NAME[] = "secret";
//IPAddress server(secret); 
String PATH_NAME = "/wtid/logCovid";
WiFiSSLClient client;

String queryString = "uuid=5555&manufacturerID=6666";

void setup() {
  //Initialize serial and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

  // check for the WiFi module:
  if (WiFi.status() == WL_NO_MODULE) {
    Serial.println("Communication with WiFi module failed!");
    // don't continue
    while (true);
  }

  String fv = WiFi.firmwareVersion();
  if (fv < WIFI_FIRMWARE_LATEST_VERSION) {
    Serial.println("Please upgrade the firmware");
  }

  // attempt to connect to WiFi network:
  while (status != WL_CONNECTED) {
    Serial.print("Attempting to connect to SSID: ");
    Serial.println(ssid);
    // Connect to WPA/WPA2 network. Change this line if using open or WEP network:
    status = WiFi.begin(ssid, pass);

    // wait 10 seconds for connection:
    delay(10000);
  }
  Serial.println("Connected to WiFi");
  printWiFiStatus();

  Serial.println("\nStarting connection to server...");
  // if you get a connection, report back via serial:
  if (client.connect(server, HTTP_PORT)) {
    Serial.println("connected to server");
    // Make a HTTP request:

    client.println(HTTP_METHOD + " " + PATH_NAME + " HTTP/1.1");
    client.println("Host: " + String(HOST_NAME));
    client.println("User-Agent: Arduino/1.0");
    client.println("Connection: close");
    client.println("Content-Type: application/x-www-form-urlencoded");
    client.print("Content-Length: ");
    client.println(queryString.length());

    char c = client.read();
    Serial.write(c);
  }

  // if the server's disconnected, stop the client:

}


void printWiFiStatus() {
  // print the SSID of the network you're attached to:
  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());

  // print your board's IP address:
  IPAddress ip = WiFi.localIP();
  Serial.print("IP Address: ");
  Serial.println(ip);

  // print the received signal strength:
  long rssi = WiFi.RSSI();
  Serial.print("signal strength (RSSI):");
  Serial.print(rssi);
  Serial.println(" dBm");
}

这是我上传该脚本时的串行监视器响应：

Starting connection to server...

disconnecting from server.

我的第二种方法是使用带有 WiFiSSLClient 的 ArduinoHttpClient，但同样没有运气：

#include <ArduinoHttpClient.h>
#include <WiFiNINA.h>

///////please enter your sensitive data in the Secret tab/arduino_secrets.h
/////// WiFi Settings ///////
char ssid[] = "secret";        // your network SSID (name)
char pass[] = "secret";    // your network password (use for WPA, or use as key for WEP)

char serverAddress[] = "secret";  // server address
int port = 443;

WiFiSSLClient wifi;
HttpClient client = HttpClient(wifi, serverAddress, port);
int status = WL_IDLE_STATUS;

void setup() {
  Serial.begin(9600);
  while ( status != WL_CONNECTED) {
    Serial.print("Attempting to connect to Network named: ");
    Serial.println(ssid);                   // print the network name (SSID);

    // Connect to WPA/WPA2 network:
    status = WiFi.begin(ssid, pass);
  }

  // print the SSID of the network you're attached to:
  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());

  // print your WiFi shield's IP address:
  IPAddress ip = WiFi.localIP();
  Serial.print("IP Address: ");
  Serial.println(ip);
}

void loop() {
  Serial.println("making POST request");
  String contentType = "application/x-www-form-urlencoded";
  String postData = "uuid=4444&manufacturerID=5555";

  client.post("/wtid/logCovid", contentType, postData);

  // read the status code and body of the response
  int statusCode = client.responseStatusCode();
  String response = client.responseBody();

  Serial.print("Status code: ");
  Serial.println(statusCode);
  Serial.print("Response: ");
  Serial.println(response);

  Serial.println("Wait five seconds");
  delay(5000);
}

这是我上传该脚本时的串行监视器响应：

making POST request
Status code: -2
Response: 
Wait five seconds

I've updated the WiFiNINA firmware and uploaded the SSL certificates via the arduino IDE to the board as well, and I am able to make SSL GET requests to sites like google.com without issue. 我确实得到串行响应，确保我连接到 wifi，只是不想把串行监视器响应的那部分。

感谢任何可以提供帮助的人
