``mqttc`` MQTT-C Example
========================
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".
