HelloMQTT over TLS.
Fork of HelloMQTT by
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.

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