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 Opening network interface... Network interface opened successfully. Connecting to host iot.eclipse.org:8883 ... Connection established. MQTT client is trying to connect the server ... Client connected. Client is trying to subscribe a topic "mbed-test". Client has subscribed a topic "mbed-test". Client publishes messages ...

Known Issues
On K64F, when serial baud rate is changed from 9600 to 115200, program fails.
