Hi,
I want to implement an MQTT-SN network with a Raspberry Pi 3B+ MQTT/MQTT-SN transparent gateway and some End-Devices in MQTT-SN.
This is working over Wifi with Paho library, but I want to implement this network with nRF52840 DKs over Thread between the gateway and the end-devices, while keeping basic images on the nordics (no MQTT-SN specific image on it, just basic, like CLI or something).
The structure is as followed: {End-Device(no internet)} <--> {nRF52840 basic image} <----(thread IPv6 network)--> {nRf52840 basic image} <--> {Raspi3B+ MQTT-SN Gateway} <--> {Azure Hub}
The main problems are:
- How do I configure the CLI image on the nRF so that I don't have to put the "udp send..." thing to send data (Or if it exists an image doing that already)?
- How to transmit Gateway data (that are, by default, transmitting data to end-devices over Wifi and IPv4) through the nRF serial connection? I mean, I could use the "socat" linux feature but how could the nRF know to which end-device he should transmit
Thanks for your help!
By the way, I'm part of an international company for this project, I would love to have a permanent contact with one of the nordic engineers to go on this project with my team. Thanks.
