STXMesh MQTT Network Information - South Texas Radio

Connecting South Texas Beyond RF Coverage

While STXMesh is built on a robust LoRa mesh network spanning South Texas, MQTT allows us to extend communications beyond the limits of direct radio coverage. MQTT (Message Queuing Telemetry Transport) enables Meshtastic nodes with internet access to exchange messages, telemetry, and position information across the STXMesh network, helping connect users in San Antonio, Corpus Christi, Laredo, the Rio Grande Valley, and other areas throughout South Texas. (rrmesh.net⁠)

MQTT serves as a bridge between separate RF coverage areas, allowing users to remain connected even when there is no direct radio path between them. It is especially useful for mobile users, travelers, and those helping expand the South Texas Mesh network. (rrmesh.net⁠)

How MQTT Works

When a Meshtastic node is connected to Wi-Fi or another internet connection, it can send selected mesh traffic to the STXMesh MQTT server. Other MQTT-connected gateways can then receive that information and distribute it to users in their local coverage area. This helps connect otherwise isolated mesh regions throughout South Texas. (rrmesh.net⁠)

Think of MQTT as a bridge between local mesh networks, helping create a larger connected community across the region.

Recommended MQTT Settings

For most users connecting to STXMesh:

MQTT Enabled: Yes
Encryption Enabled: Yes
MQTT Uplink: Enabled
MQTT Downlink: Enabled
Root Topic: msh/US/TX
Use the appropriate STXMesh channel key listed above
Enable Map Reporting if you would like your node to appear on community mapping services (optional) (rrmesh.net⁠)

Important Notes

MQTT is optional. STXMesh functions perfectly well over RF-only communications.
MQTT requires internet connectivity through Wi-Fi, Ethernet, or a client proxy connection.
Not all Meshtastic hardware supports Wi-Fi. ESP32-based devices generally provide the best MQTT support. (NodakMesh⁠)
Excessive MQTT usage can increase network traffic. Use recommended settings and community channels whenever possible.
