IoT LoRaWAN sensor join-request/join-accept message via MQTT

[MartinWareham]

Hi,

I have a LoRaWAN sensor which I can successfully connect to The Things Network via a LoRaWAN gateway.

It has an AppEUI, a DevEUI and an AppKey.

In order for it to connect it sends a join-request message and a join-accept message is sent to it (see below).

I would now like to connect the sensor locally to my PC and read the data sent from it.

Towards this end I use the ChirpStack Gateway to convert the common packet forwarded packets from the LoRaWAN gateway, and I have implemented an MQTT Broker in LabVIEW, as well as an MQTT Subscriber Client (based on this video which is very good - https://www.youtube.com/watch?v=2TUv8o7KdWc)

Does anyone know how to implement the join-request/accept from the sensor?

I presume it also means I have to use the AppEUI, a DevEUI and an AppKey in some way too in order to decrypt the payload from the sensor?

Thank you in advance for your help/guidance/ideas/experience on this, even if it isn't with LabVIEW as another possibility I have is using the ChirpStack Servers too, but would like to use LabVIEW.

Martin

Can you explain how you have done this?
