I’ve been diving into the world of MQTT connectivity with my NRF5340 and NRF9161 setup, and I’m curious to get some insights from the community. I’ve been working on modifying the SLM application on the NRF9161 to load its own TLS certificates upon startup. This seems feasible using the modem_key_mgmt functions, but I’m hitting a snag with the MQTT transport type. Since the NRF5340 is managing the MQTT connection, but doesn’t have access to the certificates stored on the NRF9161, I’m wondering if MQTT_TRANSPORT_NON_SECURE is the right approach here.
I’d love to hear if anyone has experience with similar setups or if there’s a way to securely handle certificates across these devices. Additionally, I’m curious about best practices for ensuring seamless communication between these components. Any tips or resources would be greatly appreciated!
