Thread Mesh: MQTT-SN messages forwarding to cloud.

[kumarnaveenb]

Hi,

Is their any method to listen the MQTT-SN topics inside Rpi? I would like to listen the MQTT-SN messages and send it to my own cloud. Is it possible? I have tested CoAP it is awesome. But, I need mqtt.

Thanks,

Naveen

Hi Naveen,

The border router image has a MQTT-SN gateway enabled by default. You can change the config to forward the messages to your own cloud MQTT broker.

Best regards,
Jørgen

Hi Jorgen,

Please find my config file below. I have added Brokername and Certificate folder path. Still not working. Am I missing anything?

Where I can find MQTT-SN logs?

As you can see in the note in the documentation that I linked, you need to enter the IPv4 address of the broker. The hostname is not supported.

Not that this gateway is not developed by Nordic, you can find some details about logging in the readme in the GitHub repo.
