Ill check them out, but if theres no logging on the poly side, logging on the phone is likely only going to tell me that its not working and cant connect (for whatever reason), but I would imagine it wont be able to tell me the reason why it failed in the first place. I do have bubble upnp, so I will check it.
Edit: Happened again after seriously like 1 minute of playback.
ECONNREFUSED (Connection refused)
GetPositionInfo: Error: Current state of service prevents invoking that action.
And I get a bunch of those. Also getting some failed to connect errors. Which tell me nothing, except that it seems the DLNA renderer on the poly is frozen or not working. Again, I can still fully access the DLNA library, connect via MPD and playback that way.
And while I have had other issues with the poly in the past, this is brand new and has never happened before and just seems to have started up.
Also, MPD I dont feel is a great solution either as it requires knowing the IP (which could change), and it still doesnt index mp3 files properly, requiring browsing files directly instead of an album list, which is less than ideal.
