LXI mDNS DNS-SD implemntation vs. VXI-11 for its discovery in NI-MAX

[mrechte]

Hello.

I am working on the LXI (v1.5) implementation on our embedded device. We wish the device to be discovered in NI-MAX.

So far we publish the _http._tcp and _lxi.tcp services and a web server is serving the /lxi/identifcation xml file.

We have traced the network exchanges between the PC running NI-MAX and the device. We have reached the point were NI-MAX requests the identification page (which is retuned OK). But the device remains non visible in NI MAX.

However the LXI Discovery Tool can see our device on the same PC.

Tracing some other "LXI labelled" equipment we found that NI-MAX establishes a connection with its VXI-11 server.

So the question is does a VXI-11 server also required on the device to be discovered by NI-MAX ?

Many thanks

Marc

I hope it helps, feel free to ask for more information.

Thank you

Thanks Maxime.

From my latest tests, it seems VXI-11 server is not required, but NI-MAX needs to confirm the IP address with a socket connection to the equipment.
