NRF9160 Connection to GCP via MQTT Gateway

[TysonYee]

Hi,

I was wondering if it was possible to avoid JWT for the NRF9160 by establishing connection between an MQTT Bridge to Google Cloud. Our goal is to establish 24/7 connection/highest amount of uptime to Google Cloud but with JWT, we limit ourselves to the 24 hours unless we regenerate the tokens again. I was wondering if you can give an insight on whether this is a viable option both cost and setup wise because currently the only solution I can find is only through JWT and older Nordic Google IoT samples. 

Cheers,

Tyson

Hello, 

Have you tried using our nRF9160: Simple MQTT sample, or are you talking about bridging the nRF Cloud to Google Cloud Platform?

Kind regards,

Hi,

I have tried using the Simple MQTT Sample but I think it doesn't allow GCP (Google IoT Core) communication because the device needs to be authenticated?

Yes! That is what I am looking for regarding Bridging nRF Cloud to GCP, but is it fully supported? On the guide it recommends that AWS is to be used.

Cheers,

Tyson

Googling Google IoT Core MQTT gave me this page on MQTT bridge to communicate with Cloud IoT Core. The Simple MQTT sample supports TLS to enable secure MQTT connection using the TLS overlay configuration file for found in nrf\samples\nrf9160\mqtt_simple\overlay-tls.conf. Please see the Zephyr MQTT chapter and its sample the MQTT Publiser (samples/net/mqtt_publisher).

Kind regards,
