MDNSDiscoveryService get a instance to run a startScan

[dagoodyear (David Goodyear)]

Hi all,

In a binding I’m developing, I need to get a reference to the instance of MDNSDiscoveryService, so that I can invoke a call to startStcan().

Maybe I got the wrong search criteria on the forums, or when searching the addon’s code base, but I cant seem to find a way to get a reference to that service, in order to invoke it. Any hints / guidance appreciated.

The reason is I need to trigger the mdns query so that the discovery process run, and it finds all the devices details. If I run it manually using the Scan button on the UI, it does the query and I see the desired results come in. I only want to do this if a mdns host name is detected, and nothing is currently found (will coalesce the calls to a sensible window).I just cant see how you get a reference to that service from the system, in order to force a scan?

Thanks in advance - any help appreciated as I must be missing some fundamental / basic trick here with the models openHAB uses.

Hi all, i’m closing this topic.

This was either a bug in my binding which as I have been cleaning up the code-base, around mdns discovery, or in the build I had of OH.

The system does run a scan at startup which is what is needed for the initial resolution of the names. After that when the device the binding is for restart’s, it does a push of mdns which effectively means it’s data is updated, as this is picked up by OH.

So all is good, thank you for anyone who read.
