Advanced topics

MQTT-only bot

This bot has experimental support for MQTT-only mode. If you want to use the bot without Meshtastic hardware, you need to edit mqtt.ini file and enable MQTT section in mesh.ini file.

This requires setting [Meshtastic] section device to mqtt.

APRS

This bot provides bi-directional text messaging with APRS nodes using APRS-IS. Meshtastic nodes with valid amateur call signs will be announced to APRS network. See

[APRS] configuration section.
