I'm trying to make a MQTT+TLS with CA verification Sketch for my ESP8266 but I am struggling to combine the WifiClientSecure with PubSubClient. My current Sketch is able to load and verify certificates in a separate connection from my WifiClientSecure client. But not in the connection from the PubSubClient client. How is it possible to have only one connection to the server with CA verification and establishment of the MQTT connection? Is there an example sketch available somewhere?
SPISettingsinitializes to non-standard Arduino settings?
