Fireware / Port Problem

There are some complexities about getting Macs to do the firmware update, depending on the OS you are using, but I will leave a Mac user to advise.

Although updating the firmware is a very good idea and it will help with discovery issues, I doubt that it will solve your current problem which is more likely to be because the present Naim app (since 5.7) has a bug (or a design fault) that Naim haven't been able to fix yet as it doesn't show up reliably.

My own experience is that if the app can't see all your rooms, simply killing it by tapping on the home button twice, swiping upwards, tap home button again and then reselect the Naim app almost always instantly solves the problem, until the next time.

Thanks David - I actually saw your advice earlier when I was looking for solutions, but even that doesn't seem to work. I'm not sure how a company can release software that renders their products virtually unusable, and not seeing fixing it as as being a priority. I've lost a lot of confidence in them at the moment.

Mac OS user here:

Have you followed the upload instructions that come with the upgrade package to the letter?

Do you have access to a different mini-USB cable to try?

Hi Andy

The other thing to try is restarting your router. I guess you have tried that already. I find sometimes the find rooms problem is reduced or banished for a while if I do that. The fact that everything but the Naim app is working fine doesn't mean that restarting the router is unnecessary apparently.

Thanks David. Over the past couple of days I've restarted my router and re-installed the app so many time I feel like I'm in a very dull version of Groundhog Day. I've messed around, futilely, with this for too long now. Naim caused this problem and its now their responsibility to fix it, which I'm sure they will.

Your dealer should be able to do the upgrade for you if you're having problems. 

Andy - I think I know where the problem may be...

I suspect that that the Silabs VCP driver (USB converter) fails to load correctly...
Try going directly to the Silabs website and get a latest version of the UART bridge controller.
It will only be visible in the Hardware section of your System Information once your MacBook is connected to a NAIM streamer.

I will try to copy [@mention:1566878603985147] on this thread - hopefully he can assist as well.

Thanks Adam. It looks like the documentation points to the latest release. I did download it directly just in case like you suggested, but it results in the same issue. You could be right about it not loading correctly - there's nothing for the driver in the extensions directory which I thought someone said should be present. The permissions for RWX are fine for root and it does say it has installed successfully though.

Thanks anyway. I suspect the Firmware isn't the issue with the app problems though as I've seen people posting with similar issues with the Muso. It must be possible to post an older version of the app (as Classic App or something). Hopefully their app team can sort it out next week and post an update - I can't see how they can keep these issue unresolved. Its all a very disappointing at the moment.

the UART bridge driver will only show up when your Mac is connected to a streamer. As I unsertand, despite the active connectiom, it still doesn't show up. Most odd,

On the app side - we are now testing, under the Beta programme, iOS version 5.8 - so far so good. 

Hi Adam, the connection does show up under Hardware/ USB (the CP2102 ... part), although it shows up as long as there is a USB cable connected to the lap top, it doesn't necessarily have to be also connected to the streamer.

You might have solved my problem though. I was told it wasn't possible to re-install the old version of the app that worked,  but actually it must as you have beta version of app that aren't publicly released so Naim just have to do the same process to put the old app back up. How can I I get a copy of 5.8 so see if it fixes the problem? I'm sure Naim to make sure it fixes this problem before they release it (is this version primary being released to fix these connection issues?). Thanks.

Andy - I've jus re-read your original post. The 'disappearing' streamer issue....

I don't think it's the app. I suspect there is something odd going on on your network. Do you have an app called Net Analyzer? If not it's worth buying one (the paid version, not the free). Essentially - we need to check if the Bonjour protocol is running on your network connected components.

I would also recommend re-booting all your network gear, forcing it to re-fresh (especially the IP addresses). The switch / router should be the fiest one to be switched on, followed by the rest of the components.

I'm running the 5.8 beta and it doesn't solve this problem (nor do the release notes mention it). I believe that Naim are still trying to understand what the issue is and why it affects a very small proportion of customers.

Naim could put an earlier release out if they wanted to, but 5.7.x fixed all manner of other issues and they wouldn't want to go backwards, especially with the new Atom/Nova needing those fixes. It would no doubt cost them money to have both a classic app and the current app in the App Store and there would inevitably be cases of new uniti owners using the wrong app and having problems. So I don't expect that to happen.

The beta app process works differently and isn't a way to get older versions (rather it's a way to get out newer versions pre-release). 5.6 is no longer available through the beta process.

The only way that I know of to get an older version of an app is to have already been doing full backups in iTunes and you can then restore your phone to the last backup which if it had the earlier app in the backup would mean the earlier app was restored. Obviously you can't use this approach if you haven't been doing iTunes backups!

Actually I disagree with this. One of my streamers (unitilite) never shows the B symbol when I run this Net Analyzer app but it's the one streamer least likely to be lost by the app.

I am sure the problem is the app. The problem started with the first beta of 5.7 (if you go back to the beta forum you will see some of us discussing this).  I have 5.6 still on my iPad. My two iPhones running 5.7.x lose one or more of my streamers frequently and unpredictably but my iPad running 5.6 never loses them.

But I do agree with the restarting the network suggestion.

Thanks Adam, David. I can't see how it can be a network issue when my friends iphone with the old app works as expected. To be honest this network diagnosis etc is a grey area I really don't want to go down. If I was told when buying I would have to become a network engineer to get it to work I would have steered well clear of the brand. I've wasted most of my free time last week and this weekend trying to sort this out.

I'll get Phil to speak to my dealer on Monday and they can come over and sort this out some evening next week. Presumably if they can't the unit is (and I hate the phrase) 'not fit for purpose' they will just do the honorable things and take it away and refund me.

Well - I actually disagree with David - I think it is the network at fault.

And no - one does not need to become a network engineer. I'm not, and my network has been stable for more than 2 years now (ever since I put it together). 

Andy - I understand you are frustrated, but it's not Naim's fault that various network components do not behave as advertised.
A stable network is exactly that. An unstable one behaves the way you or David describe.

I too run 5.8 Beta version and I never loose a streamer or a server from the app. I've seen various odd behaviours from Beta apps, but one thing for sure - they always find my server and my streamers.

Well disagreement is fine.

I suppose what I mean is that Naim changed something in their discovery strategy with 5.7 and it doesn't work with all the practical wirking networks that the app meets.

A good example is just now. I found the latest app on my iPhone had lost my Core, which it could see half an hour ago. I checked with Net Analyzer on that iPhone and the Core was where it always is. So I checked with my iPad running 5.6 and that could see the Core and all the streamers. I killed the app on my phone and restarted it. Immediately (as in within a fraction of a second) it found my Core and all my streamers.
