Overview
If your device is connected to WiFi you can enable it to forward messages along to an MQTT server. This allows users on the local mesh to communicate with users on the internet.
Be sure to checkout this MQTT too.

mqtt_disabled
If a meshtastic node is able to reach the internet it will normally attempt to gateway any channels that are marked as uplink_enabled or downlink_enabled. But if this flag is set, all MQTT features will be disabled and no servers will be contacted.
mqtt_server
The server to use for our MQTT global message gateway feature. If not set, the default server will be used
mqtt_password
MQTT password to use (most useful for a custom MQTT server). If using a custom server, this will be honoured even if empty. If using the default server, this will only be honoured if set, otherwise the device will use the default password (TODO - find default password).
mqtt_username
MQTT username to use (most useful for a custom MQTT server). If using a custom server, this will be honoured even if empty. If using the default server, this will only be honoured if set, otherwise the device will use the default username (TODO - find default username).
uplink_enabled
This is a channel specific setting. If your channel has this set to true and you are connected to WiFi, the device will forward along messages to whatever MQTT server is specified in mqtt_server. See Channel Settings.
downlink_enabled
This is a channel specific setting. If your channel has this set to true and you are connected to WiFi, the device will forward along messages from the MQTT server to the mesh from this device. See Channel Settings.
