Thank you for your extreme demonstration of patience and I’m sorry you’ve had to wait so long.
We’ve reviewed this case again and we’d like to verify whether you can reproduce these dropouts when connecting to the Chord Poly via Bluetooth under the same ARC connectivity conditions (Wifi or cellular).
Additionally, we want to see if you ever experience similar issues when using Roon Remote.
We’ll follow up in days, not weeks, to try to pin this down. Please let us know if we can help pick up the trail.
As I understand it, the only way for the Chord Poly to reach Roon ARC is via Apple AirPlay in order to achieve music listening at high fidelity (and not using Bluetooth as that will degrade the sound). I also desire to connect the Poly to my iPhone using hybrid hotspot mode as that allows me to have access to the web while on my phone. That setup is described here.
My setup process for Roon ARC is:
Launch Gofigure app so the iPhone can connect to the Poly
With those steps completed, I can listen to Roon ARC on the Mojo2/Poly. Typical dropouts occur within minutes, sometimes not occurring for up to 15 minutes, making Roon ARC unlistenable for all practical purposes.
Here is my correspondence with Chord as background.
I recently swapped out my router from a Google mesh router to a Synology RT6600ax (one each for the router and the mesh). Based on a few Roon ARC sessions, it appears that the dropouts are less frequent but still there. Interestingly, when I previously swapped the Google mesh router to a TP-Link AX3000 router, I didn’t hear any improvements and returned that router.
To your questions:
"We’ve reviewed this case again and we’d like to verify whether you can reproduce these dropouts when connecting to the Chord Poly via Bluetooth under the same ARC connectivity conditions (Wifi or cellular).”
–When I use Poly, I get few, but very short dropouts. These really are of a different sort and perhaps may be due to my environment where I was listening. My use of Bluetooth was limited to ~ an hour.
"Additionally, we want to see if you ever experience similar issues when using Roon Remote.”
–When I use Roon Remote at home connected to my WiFi network (now and with the earlier routers), Roon plays flawlessly with no dropouts
@mikeb- I saw the post about the update. I updated my Poly with no change.
@Connor- any progress? One of the things embedded in my email string with Mitch Duce at Chord is the following:

We have actually been in discussion with Roon on a friendly basis about ARC and how we’d like to see phones able to operate as stripped back cores running RAAT, as it would be of great benefit to Roon users with our streamers, and many other manufacturers of course.
June 9, 2023:
Until roon enable a limited core system on an iPhone, there’s no way we can change the playback codec, other than airplay and Bluetooth. So compatibility with Roon Arc is inevitably limited. Also with RAAT running they would be able to run some more in depth diagnostics which may be able to locate the bottleneck in this particular case. They’ve been able to do that in the past during our product development stages with a Core.
Thank you for your generous demonstration of patience.
RoonServer functionality on mobile devices is not something we support at this time. ARC does have identical RAAT functionality to Roon Remote, except DSP is performed locally on the phone. RAATServer is hosted alongside RoonServer on your core machine.
None of this has relevance to the errors or dropouts reported in this thread, however. What you’re experiencing, based on re-reading this thread, is the unfortunate but predictable experience of a cellular connection being less reliable than the 2.4gHz band of your WiFi network.
If you don’t have the same issue in ARC or Roon Remote on home WiFi, then connectivity is the only variable left in play.
