The mqttc demo under example path can not support mbedtls api. Because of the MQTT-C source code already contains many types of link examples, so we added the corresponding makefile to support mbedtls mqttc connections publisher and posix mqttc connections publisher and subscriber.

This is a simple MQTT publisher example using MQTT-C
By default it publishes to the "test" topic and exits. Default behaviour including, host, port, topic, message and loop count can be changed through different arguments.
To test: From the host start an MQTT broker and subscribe to the "test" topic. Here mosquitto is used:
mosquitto&
mosquitto_sub -t test
Make sure that mosquitto is not configured in local mode only.
From the nsh:
Launch the built-in app mqttc_pub specifying the host:
mqttc_pub -h HOST
The target will publish the message "test".
