ARC (still) fails during WiFi to Cellular transitions [Ticket(s) In]

ARC still can't survive WiFi --> Cell dead zone --> Cell working zone transitions

Even with the latest updates, ARC still exhibits the behaviors noted in:

This is tiresome, really. I do not feel that Roon Support has engaged with me meaningfully to get this resolved, despite repeated attempts to offer whatever information I can. I’m incredibly disappointed, to say the least. Is someone willing to actually engage me regularly to help debug this and solve it, once and for all?

The below screenshot combo should never happen, don’t we all agree? Yet this is what happens once I get back on cellular after going from home wifi to cell dead zone back to cellular functioning…

Hey @DDPS,

Thanks for sharing an updated report on this issue! Investigation into improving this behavior has been ongoing with the team, and I apologize in that none of the updates so far have helped you.

Based on the screenshot you’ve provided, we should be able to take a closer look into your Arc diagnostics to see where improvements can be made.

Thanks for your continued patience in the meantime! I hope to have additional information to share soon, once the team has had time to review your case. :pray:

Thank you @benjamin - please let me know what I can do to provide extra detail that could be of help. I would not be bothered at all if the Roon team wanted to ask me to do specific things to help debug this.

Hi @DDPS,

Thanks for your help and long-standing patience. Development is actively investigating this case, so if you continue to reproduce it anytime you leave the WiFi network, please note the timestamps here.

This will help expedite the investigation since we won’t have to corroborate each log instance against other known examples to confirm it’s a relevant symptom.

OK will do. Thank you so much @connor!

i can actually reproduce it when i’m on cell signal and have a drop in cell data it keeps showing poor connection until i restart the app. Don’t know it if its the same thing, but it feels like the same.

Hi @Edgar_Rodriguez,

Thank you for the report - are you able to provide an approximate timestamp of when this last occurred for us to attach to development’s investigation?

~7:45 AM EST, happened again for me this morning.

Hi @DDPS,

The team has just released improvements into Early Access that might improve this long-standing symptom.

However, ARC diagnostics show unrelated crashes in CarPlay more recently, so before we suggest migrating to Early Access - have you seen any new symptoms or issues with ARC?

No, I have not. Are you suggesting that you’re seeing these in my logs? Or in logs in general?

These were automated ARC crash reports on our own diagnostic servers that originated from your account.

These were UI-related and it’s entirely possible that the head unit recovered. Consider it a red herring.

In the meantime, several connectivity improvements are undergoing testing in EA and will merge into the next Roon build.

Ah - Yes, there were a couple/few times that CarPlay restarted after I used Siri while listening to Arc, and CarPlay crashed and rebooted. I forgot about those.

Thanks @DDPS, the team will review those CarPlay events independently with Devs in that case.

Happened again this morning, same time, same location.

Here’s what I want to point out, just in case it hasn’t been clear before: With two green statuses and a good LTE signal, there is no reason that the software should fail when loading a new track with a “poor connection” message. If it is truly a poor connection, one of those dots should not be green.

@connor just tagging you about the above.

I experienced this for the first time today.

I parked on my drive which is covered by Wi-Fi.

Iheart music playing on Arc I then proceeded to drive away from my house dropping onto mobile data. Arc stops playing getting similar errors to that being reported and had to force close the app.

I was listening to music on Arc whilst driving onto my drive and transitioned from mobile data to Wi-Fi without an issue.

Also to add to this, I was playing downloaded music on Arc :man_shrugging:

That’s the problem I had several time’s, and eventually decided to delete ARC for something more reliable.

If you are enjoying offline music why does a change from WiFi to mobile data even have an impact. My guess is there is some cleverness going on when a local connection is noticed.

Had this many times moving from office to outside and when I was visiting my Brother in France. Or any time ARC has a loss of signal for a sustained period it will not resume playback and get poor connection message as per @DDPS it shows as connected in ARC UI.

It’s very easy to replicate. I wonder if the Roon Devs could try it.
