Raspberry Pi – Software – Mosquitto MQTT Broker
Mosquitto MQTT Broker
MQTT (Message Queue Telemetry Transport) is een lichtgewicht machine-naar-machine berichtenprotocol voor gebruik bovenop het TCP/IP protocol. Het is ontwikkeld om eenvoudige communicatie tussen “Internet of Things”-apparaten mogelijk te maken. Het wordt bijvoorbeeld gebruikt voor geo-tracking van wagenparken, home automation, sensornetwerken en het op grote schaal verzamelen van data door bijvoorbeeld nutsbedrijven.
Mosquitto is een populaire MQTT server (‘broker’) gesteund door een actieve community en is eenvoudig te installeren en configureren.

Wheezy:
4) Update en upgrade apt-get repository listing
sudo apt-get update
Ps. krijg je een foutmelding / timeout van ppa.launchpad.net verwijder dan de java listing:
sudo rm /etc/apt/sources.list.d/webupd8team-java.list
5) Installeer Mosquitto
sudo apt-get install -y mosquitto mosquitto-clients
