Bluetooth issue with 2 H9s simultaneously

January 07, 2015 - 01:49 pm

For several weeks, I was able to connect to both of my H9s at the same time via Bluetooth and an iPad.  Now, I can can connect to only one at a time.  Both units exhibit the same behavior.  I can make the first connection to either H9.  The second connection attempt appears to work very briefly, but then quickly changes to a disconnected status.

That's interesting.  We had heard from users that were having trouble connecting to multiple H9s with an iPad Air, but this is the first time someone told us that they were able to connect to two and stopped being able to.  It would be great if you could help us figure out what might have changed in the last few weeks.  Did you upgrade to a new version of iOS?  How is the power level of your iPad?  Is it fully charged?  What if you plug it into a power source?  Does that have any effect?  If you reset your iPads settings does that have any affect?  

I wish I could give you an answer to the problem, but at the moment we're still trying to figure this out as well.

No recent updates to the iPad.  I haven't sync'd it in a while.  I have done a restart of the iPad and a "forget" on both devices.  I have also turned Bluetooth off then on again.

I will try with the iPad plugged in.  I keep it charged, so the battery level was good.  Tonight, I will cycle the Bluetooth off/on on the H9's themselves (have not done that, yet).

Is there anything else to reset on the iPad?

I am having the same problem with my iPad Air.

I can connect the first H9, but when I try to connect the second H9, the bluetooth light on the second H9 lights up for a brief moment then goes out.  On the iPad, it says "Connected", but after a few seconds it changes back to "Not Connected".

I recently purchased an iPad Air 2.  It is able to consistently connect to both H9's simultaneously.

It must be something with the iPad Air that is causing the problem.

My iPad Air is running iOS 8.1.2, while my Air 2 is running 8.1.

OK, so I *may* purchase a refurbished iPad 2 to get around this issue.  Can anyone confirm the the Control App will or will not run on an iPad2???

Also, please clarify... can Bluetooth be used on a Windows PC?  Per the Harmonizer User Guide, only USB, not Bluetooth, is supported on a PC.

(page 3...) H9’s Bluetooth function allows you to wirelessly control your H9 from an iOS device (Macs and PC’s must be connected by USB).

That contradicts information in the "H9 Control User Manual" states that a Windows PC can use Bluetooth to connect to the H9.

http://eventide.com/AudioDivision/Products/StompBoxes/H9ControlUG1.aspx

So, is this true, and can the PC control two units or just one?!?!?

Bluetooth can be run on a Windows PC to talk to an H9. But (there is always one of those) it seems to depend a bit on your BT hardware. Please search other posts for recommendations if you have problems.

As Nick mentioned above, Bluetooth is supported now on Windows, and yes, you can connect that way to two devices. Almost no Windows computers seem to come with built in Bluetooth support nowadays, and unfortunately, some of our users have had a hard time getting Bluetooth connected between their machines and the H9.  We ordered a handful of Bluetooth USB dongles off of Amazon ourselves and tested them out and posted the results to the following FAQ item on the H9 support page.

http://www.eventide.com/Home/Eventide/AudioDivision/Products/StompBoxes/H9_FAQ1.aspx#H9c3a

What Bluetooth USB dongle should I buy to let my Windows computer connect to my H9 via Bluetooth?

The H9 communicates using the 2.1 version of the Bluetooth protocol, and theoretically, any Bluetooth chip supporting Bluetooth 2.1 should work. In particular we have tested and had success using the StarTech USBBT1EDR2 Mini USB Bluetooth 2.1 Adapter, which can be ordered off of Amazon here.

We would dissuade customers however from buying a Bluetooth adapter using the Broadcom chipset, which is used in the BestBuy Bluetooth dongle products from Rocketfish and Insignia and the Inateck® USB Bluetooth 4.0 Low Energy Micro Adapter USB Wireless Bluetooth Dongle among other products. Many Windows machines do not automatically recognize USB Bluetooth dongles using this chipset, and no one at Eventide have ever been able to get the Broadcom driver to install correctly.

I just received my second H9 yesterday and had the same exact problem with both my iPad Air and iPhone 6.  Note that in experimenting, I was able to connect to both if on the "bluetooth" screen of the Settings App if I click on one of the h9's to connect, and then quickly try to tap the other to connect before the popup asking me to allow the h9 control app to access my h9.  I was able to accomplish this a few times last night on demand, so I was happy to be able to control both my h9s.  Let me know if I can gather any info to help debug this.

Rick, if this is an iOS device, perform a "Reset Network Settings" under:

Settings->General->Reset->Reset Network Settings

At first I could only attach to One H9, and only some H9's were even being discovered. After the Network Reset (which will also log you out of a WIFI session), both iPad 1's saw all four H9's, and I could Pair any three H9's I wished. Of course, I wished to Pair only two H9's with each iPad.

If you go into the Settings app and go to General at the bottom of the screen there's a tab called "Reset".  Some people who've had problems pairing with H9s have found that using the "Reset All Settings" function under this tab fixes their problem, and it might help with yours as well.  Using this function will wipe out your iPads WIFI settings and your iTunes username.  So you'll need to re-enter those but it shouldn't affect your installed apps.

No luck.  I reset the iPad twice (once was network only, and then everything).  I turned Bluetooth off/on at the iPad and on the H9s.  I can pair H9-1, but not H9-2, or I can pair H9-2, but not H9-1.  Either one will pair by itself, but not both at the same time.

I watched the H9 displays closely.  The iPad will briefly say connected, but the Bluetooth LED indicator on the H9 never illuminates and after 2-3 seconds, the iPad goes back to disconnected.

Should I try a factory reset on the pedals?  I seems to be some sort of contention between the two of them.

Well, there's two ways to reset the H9.  You can reset just the system settings, and you can do a full factory reset which wipes out your presets as well.  If you don't have any complicated MIDI map stuff it might be worth a try to reset your system settings.  (Turn the H9 off and then on again with the right footswitch and the HotKnob switch in the upper left hand corner pressed.)  I'd be surprised if this had any effect though.  This problem only seems to occur on iPad Airs, and the H9's themselves don't do anything tricky like auto reconnecting that one might imagine could contention between the two.  So, I think it's something about the iPad Air that's causing the problem.  I'll poke around on Apple's developer forums today to see if I can find out anything about this there.

My iPhone was able to pair with both H9s.  I turned the iPhone off to ensure that there wasn't any interference and the iPad Air is still not able to connect to both.  I posted the issue on another forum and guys with iPad mini's; iPad 2, etc... are fine.  The issue does appear to be with the iPad Air.  Sad

I emailed Apple about the issue to see if they have any information about it.  I had contacted the manufacturer of the Bluetooth chip we use a few weeks ago, but they didn't know anything about the problem and couldn't offer any help.

Just a thought .... have you got something else connected to the iPad air via Bluetooth?

the reason I ask is that from my experimenting any 64bit iOS device (iPhone 5S,iPad Air , iPad Mini 2 onwards) seems to allow two H9's simultaneously  wheras a 32bit device seems to allow 3 simultaneous connections.

I discovered this when I first got an iPad Air and replicated it with my iphone 5S, then an iPad Air 2 and an iPhone 6 .... all seem to allow only 2 Bluetooth devices to connect.

I then tried the same experiments on my daughter and wife's iPad Minis and iPhone 5's (2 x iPhone 5 ... NOT iPhone 5S) ... they all accepted 3 H9's

Given that all the devices were running the same level of iOS ... I would suggest it it was something to do with a change in hardware when the 64 bit platform came in or something in the 64 bit code??

But I have not seen any issue with only being able to connect only 1 H9 at a time ... only when I had another bluetooth device connected at the same time.

Not sure if this answers your question?

Unfortunately not at the moment.  I took me some time to figure out what was the right division at Apple to contact about this problem.  I wrote them on Jan 12th describing the problems you guys have been seeing and linked to this forum thread, but they haven't responded yet.

Regarding the number of connected devices... I don't have anything else connected to my iPad.  The only thing appearing in the list of Bluetooth devices are the two H9s.

FWIW I have three H9s and I am unable to connect to more than two of them at a time using either an iPad Air or a mini retina. Oddly, I am able to connect to all three on my iPhone 5.

I just today got a second H9 and I am having the same problem with my iPad Air :(

I can connect to either/or H9 but not both simultaneously to both on my iPad Air. I can successfully connect to both simultaneously on my iPhone 5.

Has anyone tried the 8.1.3 iOS update that came out a couple days ago?

I updated to iOS 8.1.3 on my iPad Air.  Same problem.  The 2nd H9 shows connected for 2-3 seconds on the iPad and then disconnects.  The H9 LEDs never show a connection.

Really bummed about this.  For now, I am using 2 USB cables to my PC.  However, I discovered that when you do that, the pedals stop receiving inbound MIDI messages.  Not a show stopper, but definitely and inconvenience.

This really sounds like it is an Apple issue - there is no reason why our units would care (or even know) how many of them were connected to your device. As mentioned above, we are trying to get information from Apple, but are not having great success. Please feel free to contact Apple about this problem.

Thank you for the quick replies, guys!!!  I bought a Kensington Bluetooth 4.0 USB adapter and it works great on Windows 8.  The drivers installed automatically and within minutes, I had both H9s paired up and working.  This is a HUGE WIN!!!

Keep coming up with great stuff.  My H9s have replaced a Timeline and BigSky.  The technology in them is head and shoulders above the other guys.

Great. Thanks for letting us know about another Bluetooth adapter that we can recommend to people. We'll have to add that Kensington product to our FAQ.

How are folks connecting to four H9's? I've been using a 4th gen iPad BT with three H9's, but attempting to attach forth detaches one of the previous ones before attaching.

Using a USB HUB with MacPro is fine with me - the H9 control app is a bit slow on my iPad.

Welp, I have several old iPad 1's with iOS 5.1.1. This versions Bluetooth can only pair to a maximum of 3 iPad's simutaneously. So I configured each iPad to pair with 2 H9's. Now I need a nice piece of hardware to make two iPad's usable. For a while there I thought I would have to use an iPad 1 for each H9 since I could only pair one H9 at a time. A network reset solved that problem. Good Stuff(tm) Thanks Eventide! :-)

I don't know if you all saw BadMelonFarmers recent post about this problem, but apparently, Apple made some changes in iOS 8.3, and he's now able to connect to 3 H9s on some of his iOS devices where earlier he had only been able to connect to one or two.  So, for those of you who had this problem, please upgrade to 8.3 and give it a try.

I have iOS 8.3 on my iPad Air and am still having the same issue.  Connect to the first just fine.  Attempt to connect to the second and the App briefly says "connected" then quickly reverts to "not connected".  The H9 itself never changes (the Bluetooth LED never comes on).

I did a "forget device" on both.  Same result.

I do have an iPad Air 2 now, but did have an Air 1 and it behaved in the same way.

I did a lot of testing and the only common thing I could find in the iPad, iPad Mini, iPhones that I had available to me was that there seemed to be a difference between the 32bit and 64 bit devices .. the newer 64 bit devices allowed less concurrent bluetooth connections.

All 64 bit devices allowed 2 Bluetooth connections

All 32 bit devices allowed 3 Bluetooth connections

I tested the following devices:-

iPad Air 1 - 64 bit

iPad Air 2 - 64 bit

iPone 5s - 64 bit

iPhone 6- 64 bit

iPad Mini - 32 bit

iPad Mini - 32 bit

iPhone 5 - 32 bit

iPhone 5 - 32 bit

since iOS 8.3 the iPad Air and iPhone 6 will now allow me to connect all three of my H9's and in the case of my iPhone and other device as well.

I have not gone back and tested the 32 bit devices and no longer own the iPhone 5S or iPad Air 1

That's a shame.  We had filed a bug report with Apple at bugreport.apple.com.  After reading our report they asked us to submit a Bluetooth log where we turned on a setting that enabled Bluetooth diagnostic logs and reproduced the problem.  If it's important to you to have this working, you may want to consider doing the same.

Ipad Air connection issues

June 12, 2015 - 12:22 pm

I'm a new user with 2 H9s (Core and Max) on my board.  They are fantastic!  

Also having major Ipad Air issues with connecting via Bluetooth.   I have the latest update on pedals and iPad air.  

I know that this is a problem because of the number of other users that are also having this same issue. I have an older iPad 2 and it works perfectly with the pedals as they both connect to it without issue.

With the Air, I can get them working but it literally takes me about 5 or 6 tries for the second pedal to connect.  The pedal connects perfecting and right away with my older iPad.  

Would it be possible to resolve this at some point?  

Thx for the great work and the great pedals!

As I mentioned before, I had filed a bug report with Apple about this issue. They sent me an email and asked me to verify whether the problem was fixed in iOS 8.3. I have an iPad Air, and after I upgraded to iOS 8.3, I can't reproduce the problem any more. It would be helpful if one of you guys that are still having problems using iOS 8.3 could help me submit a Bluetooth diagnostic log to Apple showing the problem.

In order to do create a Bluetooth log, I'm going to need to email you a file to enable Bluetooth logging on your iOS device and instructions, but it's pretty straight forward to create a Bluetooth log. It shouldn't take more than five minutes. If anyone can help me out with this, please send an email to my user name plus @eventide.com, or you could email support@eventide.com.

Thanks for the info in this thread. I just purchased an Air 2 and was only able to get two of my three H9s to connect. I previously used an older ipad with no issues. I checked my software version and I was on 8.1. I upgraded to 8.3 and all is well with all three H9s present and ready for action.

Apple requested that we send them 3 H9s so that they can look into the problem with some specialized Bluetooth tracing hardware that they have in house.  So, we've sent them three H9s to look at.  I apologize that it's been taking so long to get this fixed, but things are happening...

Nick, if you get some useful response from Apple, is there some arbitrary limit for 3? It would be nice for 4 H9's, or even the max of 5 to be managed from the same iOS device.

But, he says that 3 is a limit set by Apple, so unless you have influence with them, our hands are tied. Sorry.

July 20, 2015 - 06:59 pm

Good news for me.  I was able to connect both H9s simultaneously to my iPad Air.  I have recently updated both the iOS and the H9 Control App, so I don't know which update fixed my issue, but after months of not being able to use my iPad and I am now in business.
