MQTT Bridge - Tool to transfer data from an MQTT broker to another MQTT broker

This software module transfers data for selected topics from an MQTT broker to another MQTT broker.

If you don't like to configure your MQTT broker for bridging you can choose this tool.

The solution is based on the mqttsub tool (https://gist.github.com/pvtom --> mqttsub.c)

Prerequisite

mqttbridge needs the library libmosquitto. For installation please enter:

sudo apt-get install libmosquitto-dev

git clone https://github.com/pvtom/mqttbridge.git
cd mqttbridge

To build the program use

gcc mqttbridge.c -o mqttbridge -lmosquitto

Please start the program with

./mqttbridge

The available parameters will be displayed.

./mqttbridge --src_host host1 --dst_host host2 -t "smarthome/#" -t "devices/+/temperature"
