WiFiNINA - SSL client connect by IP Address is freezing

Hardware MKR Family MKRWIFI1010
1

Hello everyone. I just find 2 issues about WiFiNINA library.
Does anyone try SSL client connect using this library?

Issue #1
SSL client connect by host name is too slow, around 4-6 seconds.

#include <SPI.h>
#include <WiFiNINA.h>

#define WIFI_SSID "SSID"
#define WIFI_PASSWORD "PASSWD"

int status = WL_IDLE_STATUS;
WiFiClient client;
unsigned long start_ms, stop_ms = 0;

void connect_wifi();
void post_write_data();
void post_read_data();
void printWiFiStatus();

void setup() {
  // put your setup code here, to run once:
  // 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
  }

  Serial.println("################################################################################");

  connect_wifi();
  post_write_data();
}

void loop() {
  // put your main code here, to run repeatedly:
}

void connect_wifi()
{
  Serial.println("[LOG] Connect Wi-Fi");
  
  start_ms = millis();
  
  // 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:
  Serial.print("[LOG] Attempting to connect to SSID: ");
  Serial.println(WIFI_SSID);
  status = WiFi.begin(WIFI_SSID, WIFI_PASSWORD);

  stop_ms = millis();
  
  printWiFiStatus();
  
  Serial.print("[LOG] Connected to wifi using ");
  Serial.print((stop_ms - start_ms));
  Serial.println(" ms");
  Serial.println("");
}

void post_write_data()
{
  String PostData = "{\"device_id\": \"DEV0000001\", \"station_id\": \"STA0000001\", \"rfid\": \"000001\"}";
  char server_url[] = "www.WEBSITE.com";
  IPAddress server_ip;
  
  Serial.println("[LOG] DNS Lookup");

  start_ms = millis();
  
  WiFi.hostByName(server_url, server_ip);

  stop_ms = millis();
  
  Serial.print("[LOG] Get IP Address ");
  Serial.print(server_ip);
  Serial.print(" using ");
  Serial.print((stop_ms - start_ms));
  Serial.println(" ms");
  Serial.println("");
  
  Serial.println("[LOG] Starting connection to server...");

  start_ms = millis();
  
  if (client.connectSSL(server_url, 443)) {

    stop_ms = millis();
    
    Serial.print("[LOG] Connected to server using ");
    Serial.print((stop_ms - start_ms));
    Serial.println(" ms");
    Serial.println("");
    
    start_ms = millis();
    
    client.println("POST WEBSITE PATH HTTP/1.1");
    client.println("Host: www.WEBSITE.com");
    client.println("Content-Type: application/json");
    client.println("Authorization: Beare BEARE");
    client.println("Connection: close");
    client.print("Content-Length: ");
    client.println(PostData.length());
    client.println();
    client.println(PostData);
  }

  while (!client.available());

  // if there are incoming bytes available
  // from the server, read them and print them:
  while (client.available()) {
    char c = client.read();
    Serial.write(c);
  }

  if (!client.connected()) {
    Serial.println();
    Serial.println("[LOG] Disconnecting from server.");
    client.stop();
  }

  stop_ms = millis();
    
  Serial.print("[LOG] Send data to server using ");
  Serial.print((stop_ms - start_ms));
  Serial.println(" ms");
  Serial.println("");
}

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");
}

How to get the best out of this forum Installation & Troubleshooting

Hello, Welcome to the Arduino Forum. This guide explains how to get the best out of this forum. Please read and follow the instructions below. Being new here you might think this is having rules for the sake of rules, but that is not the case. If you don’t follow the guidelines all that happens is there is a long exchange of posts while we try to get you to tell us what we need in order to help you, which is frustrating for you and frustrating for us. The people who try to help with your pro…

It will help you get the very best out of the forum in the future.

  • Your OS and version can be valuable information, please include it along with extra security you are using. Antivirus etc.
  • Always list the version of the IDE you are using and the board version if applicable.
  • Use quote or add error messages as an attachment NOT a picture.
  • How to insert an image into your post. ( Thanks sterretje )
  • Add your sketch where applicable but please use CODE TAGS
  • Add a SCHEMATIC were needed even if it is hand drawn
  • Add working links to any specific hardware as needed (NOT links to similar items)
  • Remember that the people trying to help cannot see your problem so give as much information as you can

COMMON ISSUES

  • Ensure you have FULLY inserted the USB cables.
  • Check you have a COMMON GROUND where required. ( Thanks Perry)
  • Where possible use USB 2.0 ports or a USB 2.0 POWERED HUB to rule out USB 3.0 issues.
  • Try other computers where possible.
  • Try other USB leads where possible.
  • You may not have the correct driver installed. CH340/341 or CP2102 or FT232 VCP Drivers - FTDI
  • There may be a problem with the board check or remove your wiring first.
  • Remove any items connected to pins 0 and 1.

COMPUTER RELATED

  • Close any other serial programs before opening the IDE.
  • Ensure you turn off any additional security / antivirus just to test.
  • There may be a problem with the PC try RESTARTING it.
  • You may be selecting the wrong COM port.
  • Avoid cloud/network based installations where possible OR ensure your Network/Cloud software is RUNNING.
  • Clear your browsers CACHE.
  • Close the IDE before using any other serial programs.
  • Preferably install IDE’s as ADMINISTRATOR or your OS equivalent

ARDUINO SPECIFIC BOARDS

  • CH340/341 based clones do not report useful information to the “get board info” button.
  • NANO (Old Types) some require you to use the OLD BOOTLOADER option.
  • NANO (ALL Types) See the specific sections lower in the forum.
  • NANO (NEW Types) Install your board CORE’s.
  • Unless using EXTERNAL PROGRAMMERS please leave the IDE selection at default “AVRISP mkII”.
  • Boards using a MICRO usb connector need a cable that is both DATA and CHARGE. Many are CHARGE ONLY.

CREATE editor install locations.

  • On macOs ~/Applications/ArduinoCreateAgent-1.1/ArduinoCreateAgent.app/Contents/MacOS/config.ini
  • On Linux ~/ArduinoCreateAgent-1.1/config.ini
  • On Windows C:\Users[your user]\AppData\Roaming\ArduinoCreateAgent-1.1

Performing the above actions may help resolve your problem without further help.
