Ok, I got my Bond Bridge Pro, thanks guys.
1. Connected via WiFi - tried to update FW (from 2.17.2 to 2.17.4) - keep getting error 107
Connected via Ethernet - after a couple of err. 107 managed to update FW.
1. Start HomeSeer plugin - mDNS discovery gets confused by two services found (one without IP):

Not that it’s helpful in this case, but on my network, I do not see a “-1” or “-2” suffix’d listing.
My only mDNS entry is of the Bond Pro ID directly, and it resolves correctly.
@endy - is this something you’ve seen in any of your test setups or do you otherwise have an idea why Alex might be seeing this in his environment?
@merck - another instance where ethernet seemed to be the fix for 107 (but I think you’re already tracking this on the 2.17.2 upgrade)

About the FW update issue, we have done a lot of investigations, but couldn’t find the cause. The good part is that looks like v2.17.4 fixes it.
I believe @alexbk66 is seeing two services because the device is connected over Ethernet and has the Wi-Fi set up.
Can you try to disconnect from Ethernet or forget the Wi-Fi and check if you have any different results?

ahhh, yes, thanks @endy - that makes sense.
I set up the Pro with PoE / ethernet initially, so I never activated / set up WiFi on this unit.

Ah, that’s a good point. This could cause some trouble if one of the interfaces goes down and then the mDNS name is stuck with the `-2` on it. That could make it harder for the app or other API clients to connect. All the more reason to use BPUP discovery 🙂

So Chris, is it something you could fix? Zeroconf I suspect is more popular than BPUP discovery… BTW, what’s BPUP discovery?

We cannot fix the mDNS standard, which is braindead in a few ways, in particular not handling multiple interfaces well.
We could discourage users from setting up both Wi-Fi and Ethernet, or forcibly disable this via the firmware.
But it’s a quite minor issue I think. There’s only an issue if users (a) use both Wi-Fi and Ethernet simultaneously and (b) one of these interfaces has a connectivity issue during discovery.

The only reason why I had to setup Ethernet - because I couldn’t update FW via WiFi (error 107).
And I can’t understand the mDNS problem with two interfaces - if each interface has its own IP - then mDNS could report two different services on two different endpoints?
And I know what BPUP is (I use in HomeSeer integration) - I just can’t see how it can be used for discovery (BPUP **discovery** )?

I guess we don’t document the discovery use case.
Basically, you can send a BPUP packet to the broadcast addr (255.255.255.255) and all Bonds on the local network will reply with their Bond IDs (and you’ll get the IP addr from those replies’ metadata).
And, in firmware v2.18+, we’ve added `d` (discoverable) and `v` (version) fields on mDNS, BPUP, and MQTT, to save some requests in discovery. (This _is_ discussed in the latest API docs.)
