ESP32-Mqtt was not connected using Azure SSL Certificate
Hi,
ESP32-Mqtt was not connected using Azure SSL Certificate
I am using the below code for connecting with ssl certificate was not working.
#include <WiFiClientSecure.h> const char* ssid = "xxx"; // your network SSID (name of wifi network) const char* password = "xxx"; // your network password const char* server = "xxx.azure-devices.net"; // Server URL const char* test_root_ca= "-----BEGIN CERTIFICATE-----\n"
"-----END CERTIFICATE-----\n";
// You can use x.509 client certificates if you want const char* test_client_key = "-----BEGIN RSA PRIVATE KEY-----\n"
"-----END RSA PRIVATE KEY-----\n"; //to verify the client
const char* test_client_cert = "-----BEGIN CERTIFICATE-----\n"
"-----END CERTIFICATE-----\n"; //to verify the client WiFiClientSecure client; void setup() { //Initialize serial and wait for port to open: Serial.begin(115200); delay(100); Serial.print("Attempting to connect to SSID: "); Serial.println(ssid); WiFi.begin(ssid, password); // attempt to connect to Wifi network: while (WiFi.status() != WL_CONNECTED) { Serial.print("."); // wait 1 second for re-trying delay(1000); } Serial.print("Connected to "); Serial.println(ssid); client.setCACert(test_root_ca); client.setCertificate(test_client_cert); // for client verification client.setPrivateKey(test_client_key); // for client verification Serial.println("\nStarting connection to server..."); if (!client.connect(server, 8883)){ Serial.println("Connection failed!"); } else { Serial.println("Connected to server!"); } } void loop() { // do nothing }
This is not the proper repo.
WiFiClientSecure does not belong here:
[paho.mqtt.embedded-c]$ grep -R WiFiClientSecure *
[paho.mqtt.embedded-c]$
Go to the place where you got your code from and ask there. You might be having WiFi or TLS issues, or you might not have properly configured your device with your provider; make sure you report what does not work.
Here i attched the screenshot, I don't have any error,wifi was connect but server was not connected. https://prnt.sc/10hzcyf
Hi, I am using this below code, it shows Failed message.
