How can I use one-way SSL authentication with ESP32?

hey, does anyone have an example of how to use one-way SSL Authentication with ESP32?

You can use wifisecureclient for that. Instead of passing in the default WiFiClient construct the thingsboard object with a WiFiSecureClient like so:

WiFiClientSecure wifi_client;
Thingsboard thingsboard(wifi_client);

...
void setup() {
  // if using self-signed set the client to not validate the certificate
  wifi_client.setInsecure();
  thingsboard.connect("demo.thingsboard.org", "my_token", 8883);
}

pay attention to connect to thingsboard with port 8883. Also you need to have mqtts (mqtt over ssl) enabled in thingsboard.conf. Check the docu for that.

@imbeacon I think this issue can be closed, the WiFiClientSecure works perfectly with the library and a few example do contain how to connect securely as well.
