Hello!
Can anyone help me connect LabVIEW with Node-RED?
I already have the broker communicating with Node-RED, but I could not figure out how to establish the same communication between LabVIEW and Node-RED through the broker!
I followed everything I found online, but nothing has worked so far.
Thank you in advance.

Hi,
Same thing here, bro.
I did everything I could, but it is still not working.
The moment I establish the communication, the Connect to Server block returns “Connection accepted.” However, right after that, Error 66 pops up and says the server is disconnected again:
MQTT Client.lvlib:Session.Client.lvclass:Send Packet.vi:6230001 <ERR> Server disconnected
So basically, the connection is accepted first, but then the server immediately disconnects during the MQTT packet send process.
I am stuck at the same point as you, bro.
