On M5Core2 I am not getting a working https request (WiFiClient). What do I wrong?
-
Good day,
The following example for a https request is not working for my M5Core2. I don't see what I am doing wrong.
Has anybody a clue why the example is not working?
Added:
- source and
- Serial log. The last line printed is 'DEBUG 001' followed by 'DEBUG 002'.
#include <WiFi.h> char ssid[] = "<SSID_var>"; char password[] = "XXXXX"; char server[] = "www.google.com"; WiFiClient client; int status = WL_IDLE_STATUS; void setup() { //Initialize serial and wait for port to open: Serial.begin(115200); delay(1000); } void loop() { WiFi.begin(ssid, password); // Attempt to connect to Wifi network: while (WiFi.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: delay(1000); Serial.print("."); } 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, 443)) { Serial.println("connected to server"); // Make a HTTP request: client.println("GET /search?q=arduino HTTP/1.1"); client.println("Host: www.google.com"); client.println("Connection: close"); client.println(); Serial.println("DEBUG 001"); } Serial.println("DEBUG 002"); // 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 the server's disconnected, stop the client: if (!client.connected()) { Serial.println(); Serial.println("disconnecting from server."); client.stop(); } // do nothing forevermore: while (true); } void printWifiStatus() { // 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); // print the received signal strength: long rssi = WiFi.RSSI(); Serial.print("signal strength (RSSI): "); Serial.print(rssi); Serial.println(" dBm"); }

Hello @Mickey95
I don't think WiFiClient can handle HTTPS requests. I think you need to use WiFiClientSecure for that.
Thanks

@felmue Thank you for the answer. This is working! Meanwhile my own example is working using an updated PEM certificate :-)

Can we see the code?

@felmue Thank you for the answer. This is working! Meanwhile my own example is working using an updated PEM certificate :-)
So It was the PEM certificate that was the cause?
How did you discover that? -
@mickey95 dude?
