Description of Issue

The iPhones and iPads are a couple of years old and I‘m having trouble with the ones using iOS 12.5.6. Every time I start Roon ARC (builf 106) on this devices the app freezes and only the white screen with the Roon ARC logo is shown and nothing happens.

I tried to delete the app and made a new installation of it. Unfortunately same behaviour, both on the iPhone and on the iPad.

Does anyone else has this problem?

Hey @Reinald_Rudtke,

Thanks for your patience while we continue to address each thread. I’m sorry to hear you’re having issues getting Arc functioning on some of your iOS devices :-1:

If possible, could you list each device more specifically?

Is there any specific reason you’re keeping these devices on 12.5.6? Do you experience any issues using the same devices as normal Roon Remotes?

I’ll be on standby for your reply :+1:

Hi Ben,

it‘s an old iPhone 6 where Roon ARC isn‘t running. IOS 12.5.6 is the latest supported system for this iPhone. After pressing on the icon a white screen with the Roon ARC logo appears but nothing else happens. It seems the app is frozen.

For tests only I‘ve installed Roon ARC on an old iPad Air 2, with IOS 12.5.6 as latest supported system. Same behavior as on the iPhone 6.

With both devices are no issues with the normal Roon app.

Hey @Reinald_Rudtke,

After discussing this issue with the Arc team further, it has come to my attention that Arc will soon require iOS 14 as its minimum requirement, largely due to the new features being added. This will take place with our next release which will be happening this week.

I noticed you have a handful of other mobile devices that should be good to go with Arc. May I ask what your use case is for the older devices? Perhaps we can find a suitable workaround for the older devices with this update in iOS requirements.

Let me know :pray:

Hi Ben,

thanks for your response. I try to explain how I use Roon.

I’m using following devices (supported OS in brackets) in my home to remote the ROON server. The devices are installed fix on the wall in several rooms. In addition in each room a Raspberry Pi is installed fix, because I want use a cable connection to my ROON server. iPhone 6s (iOS 15.7.2), iPhone 8 (IOS 16.2), iPad Air 1 (IOS 12), iPad 6 (iPadOS 16.2), Raspberry Pi 3b (HiFiBerryOS) with a HIFIBERRY Digi+ Pro, Raspberry Pi 3b (HiFiBerryOS) with a HIFIBERRY DAC+ Pro, Raspberry Pi 4 (Pi OS, ShairPort) with a HIFIBERRY DAC+ Pro.

For mobile purposes (e.g. car, fitness center, plane) I want use Roon ARC. But it’s very inconvenient getting Roon ARC running, when connection changes between cellular, hot spot or wireless network at home. After every change I have to re-start Roon ARC. For example: When I leave my house and Roon ARC is running on my iPhone 11 (IOS 16.2) and sitting in my car I have to cut the connection to my wireless network and must re-connect via cellular. After this I can run Roon ARC and connect the iPhone via USB-C with the multimedia system in the car (Audi A4. Every time after plugging in the USB cable on my iPhone pops up a window and I must confirm, that I don’t want use Apple CarPlay. To avoid this cumbersome process I would like to leave a iPhone 6 (IOS 12.5.6) with a large memory (128 GB) in my car, which is permanently connected to the multimedia system. But Roon ARC 1.0 (128) seems not running on IOS 12.

Hey @Reinald_Rudtke,

Thanks for the breakdown here!

Unfortunately, there isn’t much wiggle room around using Arc with an iOS version below 14 after this recently release (which included carplay, so you can now go that route if you’d like on up-to-date devices.)

And on a separate note, this reminds me of the iPod days! Could such devices be making a comeback?

Do you only run into issues with Arc when swapping connections? From personal experience, I will sometimes run into this hiccup no matter the streaming service. If I’m on top things (which only happens sometimes) I’ll cut wifi off while still in the house before hopping into the car, which always seems to work much smoother.

Hi Ben,

there are issues when connection change. I tried to use WLAN in the fitness studio or at a friend’s home. But it doesn‘t work. Everytime I got the information from ARC that the connection is poor. Maybe the routers at there don’t allow it. I don’t know. ARC with WLAN only works at my home. But when I switch off WLAN at the phone ARC works good with the cellular connection. Now I use a iPhone 8 or iPhone 11 with IOS 16.2 and switch off WLAN when I leave my home. Then ARC works very well in my car and at the fitness studio.

Hey @Reinald_Rudtke,

Got it, so you’re really only running into issues when using wifi at a friends house? But, when on cellular service all is well?

The best next step, in this case, would be to take note of the date and time the next time you run into this issue and share that information here. :+1:
