Ok. Thanks for your answer.
Where can I find a manual or information about the relation of variables from configure command and mosquitto ?
I need configure something especial on mosquitto ?
I'm newest and I have a lot to learn and read. Sorry.
I installed a RaspPi MQTT Gateway with the command
./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1
It's mean that now I have a MQTT Broker on the standard port or I must to install a mosquitto or similar ?
