mosquitto

Using mosquitto on a mac

1. install mqtt server

sh brew install mosquitto

1. start the mqtt server

sh brew services restart mosquitto

1. Do a quick test of server, start a subscriber on a topic:

Note: this will wait until you press control-c (publish a message, see below)

sh mosquitto_sub -t test/hello

1. In another window, publish a message to that topic:

sh mosquitto_pub -h localhost -q 0 -t test/hello -m 'yo!'

1. For Meshtastic to be able to access that server, two settings need to be changed in the /usr/local/etc/mosquitto/mosquitto.conf file:

shell listener 1883 0.0.0.0 allow_anonymous true

1. Restart the service:

shell brew services restart mosquitto

1. If you are using the mac firewall, you will need to go into: System Preferences > Security & Privacy > Firewall > Firewall Options and add it.
