Installation packages
On Raspberry PI 5 (running 64bit OS) Paho Mqtt can be installed with C++ support. This failed on Raspberry pi 4 (running 32 bit OK - due to Lidar support for YD Lidar S4B).
However, the C interface API works on Raspberry 32bit OS (Bullseye).
Install:
sudo apt install libpaho-mqtt-dev libpaho-mqttpp-dev mosquitto-dev mosquitto-clients
- in addition to other packages required for normal compile
This should allow the teensy interface to compile.
Documentation MQTT API
For Paho-mqtt, see https://eclipse.dev/paho/files/paho.mqtt.python/html/index.html
Configure Mosquitto
Copy the full option list example to /etc/mosquitto/conf.d/:
sudo cp /usr/share/doc/mosquitto/examples/mosquitto.conf /etc/mosquitto/conf.d/
Uncomment and change in the 'listener' group:
#listener listener 1883
In the security group:
#allow_anonymous false allow_anonymous true
Restart mosquitto to take effect.
sudo service mosquitto restart
