Update for ESP32 #152

Closed brentru closed 3 years ago

brentru commented 3 years ago

The latest ESP32 Arduino Core (1.0.6 and above) requires a call to SecureWiFiClient.setCACert() for TLS/SSL connections. The secure wifi client in previous versions didn’t require this function to be called in order to establish a connection with Adafruit IO's MQTT server.

This pull request updates the AdafruitIO_ESP32. wifi adapter files to include the root certificate and updated code.

This has been tested with the pubsub example and an Adafruit FunHouse ESP32-S2
