HelloMQTT over TLS

This program is a fork of HelloMQTT. Added TLS capability by using TLSSocket library. Tested on K64F.

This sample program connects to iot.eclipse.org:8883 by default. Verifies server identification. Subscribes a certain topic. Then publishes three messages with different QoSs, i.e. QoS0, QoS1, and QoS2.

Warning

Some brokers do not accept QoS2 and/or QoS1 message. For example, AWS IoT Message Broker doesn't accept QoS2. In such broker, this program doesn't work as is. Change QoS level.

Output from console

HelloMQTT: version is 0.70
