AsyncMQTTClient does not work for SSL enabled brokers

[mjangir]

The UI doesn't accept port 8883 and 8884 for MQTT as AsyncMQTTClient does not support SSL connections.

To my knowledge AsyncTCP on ESP32 does not yet have SSL support:

me-no-dev/AsyncTCP#48

Last time I looked at this it appeared that SSL requires too much RAM be be feasible on the esp8266 with all of the other stuff the framework holds in memory - it needs about 20k of RAM just to to the handshake.

Why not just use https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/protocols/mqtt.html
