mqtt-stream

MQTT client that creates a data stream using two topics

• Data from topic from goes to stdout.
• Data from stdin goes topic to.
• If echo is enabled: data from topic from goes to topic to.

Launch mqtt-stream --help to see all available parameters.

Echo example using mosquitto

Create a subscription to foo topic using mosquitto_sub

mosquitto_sub -h test.mosquitto.org -t bar

Launch mqtt-stream with echo enabled

mqtt-stream --host tcp://test.mosquitto.org:1883 --from bar --to foo --echo

Publish some data to topic bar using mosquitto_pub

mosquitto_pub -h test.mosquitto.org -t bar -m "hello world"
