ST Platform mDNS?

Regarding looping - sure I’m sure it works, but it seems to me a very inefficient way to do it, as you’re creating/opening/closing sockets 30 times in a 30 second scan. And it leaves open the chance that you’re going to miss something. Why not just keep scanning for a specified period of time?

Re. TXT strings: are we on different firmware? I’m on 46. And it’s coming back as a table array of individual characters, rather than a string.

it seems to me a very inefficient way to do it, as you’re creating/opening/closing sockets 30 times in a 30 second scan

I think they are doing it this way because the drivers are expected to yield and check should_continue during discovery. There is a mdns socket in the Edge SDK. Maybe it is leveraging some sort of shared resource that can’t be locked up.

@TAustin

are we on different firmware? I’m on 46

Yes. I’m on v45 and get a true array of strings. Not planning to release this until I can verify it on v46.

[blueyetisoftware]

I confirmed that I see the same thing as you on v46. I’ll have to update the v45 wrapper to match the byte array.
