RUTX50 GPS-data over internal MQTT Broker

[SeTe]

This question has been handled before, but things have changed in the RUTX50 firmware and it seems to been have made easier, but I can’t get it to work anyway… I Hope someone can help with some guidance.

I have:

• GPS signal with external antenna in the RUTX50
• MQTT broker enabled in the RUTX50 with default settings & anonumus access
• Modbus TCP server enabled on the RUTX50 with default settings
• Modbus TCP client enabled on the RUTX50 with default settings, collecting Register number 144, 146, 180 & 184 OK.
• MQTT Modbus Gateway enabled on the RUTX50 connecting to host 127.0.0.1 on port 1883 & request/response topics “gpsrequest” & “gpsresponse”.
• An external IP-device connected on the RUTX50 LAN containing a MQTT client. It’s connected OK to the RUTX50 MQTT Broker.

When setting up a MQTT subscription on the external IP-device I can’t get any data. Not sure what subscription filter and topic prefix to use to collect the GPS-data from the RUTX50.

Hi SeTe,

Welcome to Teltonika Networks Community!

We do have a detailed article discussing the steps on how to configure Modbus MQTT gateway in our devices. Kindly refer to this link as a guide.

Let me know if this helps.

Thanks!

I actually solved this in another way:
Modbus TCP Server → Modbus TCP Client → Data to Server → MQTT Broker
All of the above in one RUTX50 router. Then MQTT Client in an external device to retrieve data.

The solution in this case is to publish GPS-data as an overlay in vehicle IP-cameras.
