On that what @falkTX told you before is a better input than I can give you.
This weekend I connected the Dwarf to a tablet via Bluetooth (first time I did it) and I was kind of rusty on how to do the connection. So I forgot that the first time you connect the device, you need to thick a box on the settings of the Bluetooth paired devices list that says something like “Use this device to connect to Internet”
Yes I understand but.
But the android device must be connected to the Mod Duo X bluetooth to have the permission to thick that modem via bluetooth option.
So every time I thick this box I have a error message impossible to connect the bluetooth modem blablabla…
The problem is andoid device see the Mod Duo X bluetooth bit can’t make a connection.
HI @jon
I always have the same bluetooth connection issue. Whatever the android device I use, whatever the bluetooth dongle I used, the android device error is “password error” for older android version or when it is connected to mod duo x I don’t have the check box that says “use this device to connect to internet” for the most recent android version.
I’ m using bluetooth 4.0 dongle because I understood that bluetooth 5 is not supported.
I really want to use my tablet instead of my computer to connect to the mod duo x.
Any idea?
Have you ever added a password upon request?
It is 0000 I believe. You also need to set on the android that you will access the internet from the MOD DuoX.
Salut Julien,
I have the same issue with my eink tablet, but weirdly it worked some times ago (before I send it to repair), and now it keeps telling me “Cannot establish association with MOD Dwarf 01-00506 due to incorrect code or access key.” when it stops trying to connect.
The password is never asked in this process… so I’ve never could try forcing 0000 !
For adding strangeness I don’t have any problem connecting with my phone or with my computer (with the same bluetooth 5.0 dongle on the dwarf) !!!
Is there a way to clear bluetooth setting in the device through ssh ?
Hey Romain,
I would say that this is an issue on the tablet side. Have you set it up to get the MOD Dwarf as an Internet access device?

The MOD units are very frisky when it comes to bluetooth, they will accept all connections you throw at it.
So for the case of a unit failing to connect to a specific device, but connecting to others, it is likely a setting in that device that has marked the MOD unit as untrusted.

Well I have done all test I could with 3 android devices.
I know how to use bluetooth with mod devices because before the mod duo x I had a Mod Duo and used it with bluetooth connection with all my android devices.
But with this Mod Duo X I never had the change to make it work.
The possibility to edit a pedalboard or save snapshot with a android device is for me what make me choose a Mod Device. If I know I couldn’t do it I would never bought a Mod Device. Because editing on the go is the first thing I wait from a such device.
So for my testing I tried two bluetooth V4 dongle.
For each android device I switch off Wifi and 4G internet so the device has only bluetooth connected.
With my old nvidia tablet I could first connect bluetooth to Mod Duo X but couldn’t check internet acces thru bluetooth device.
I tried again and then I simply couldn’t connect to Mod Duo X bluetooth
With my phone, a Crosscall action X3 android device, I can connect to Mod Duo X bluetooth but couldn’t check the box to use internet thru this bluetooth connection.
With my samsung S4 tablet I can connect to Mod Duo X bluetooth but the option for this bluetooth connection is empty! No box to check!
All these devices were perfectly working in bluetooth with the Mod Duo, not with this Mod Duo X.
So I would like to know if someone in Mod team or in user group can use his Mod Duo X with bluetooth and a android device???
That’s a shame that Mod Duo X , the bigger Mod Device cannot be used with a android device or have a minimum possibilities to save edit snapshot like Dwarf does. I was really hoping to be able to edit a pedalboard without using my computer and not be dependent of it with this Mod Duo X.
Did I made the wrong choice?
It’s up to you mod team to show me I didn’t. Could you solve this issue?
Hi, I have same problem with Dwarf and 5.0 bluetooth dongle which works perfectly with Apple devices. No luck with other Android devices (different versions and vendors).

I know bluetooth V5 have issue with any android. But bluetooth V4 shouldn’t be a problem.
Did you tried with a V4 bluetooth dongle? It should solve your problem with your Mod Dwarf.
Mod Duo X have another issue that Mod team seem to not take into account because I think only few Mod duo X owners want to use a android tablet to edit pedalboard. Perhaps most users connect their Mod Duo X to a computer.

I use an iPad for everything. I know for a fact my BT5 dongle doesn’t work 
However my BT4 dongle works great.
I’ve had to pull my dwarf out for the time being until I can find another device to access the dwarf gui while I’m working with the MDX on my iPad.
Unfortunately I can only access one USB port on my iPad, and that’s where my audio interface connects to record. So iPad has to be BT, and the dwarf has to have USB to access the gui.

I do this quite often. With an old HP android running Android version 4.4.2.
Even the other day needed to to some adjustments on the go really fast (something went wrong in a rehearsal) and I just swapped the dongle from the Dwarf to the DuoX and it was super fast to get it working.
Again, I feel really unlikely that this issue is related to the MOD DuoX and not with the dongle and/or tablets - but @falkTX may have a different opinion. Have you tried even something like a factory reset on the tablet(s) or so?
This is a pretty high state assumption and not accurate. The Bluetooth system in all the devices is pretty much the same. That’s even why we recommend using Bluetooth 4 dongles because Bluetooth 5 is not tested enough. If the function was not working and tested why should we make it available on the MOD DuoX at all (?!).
I already successfully used either MOD Duo, MOD DuoX and MOD Dwarf with the Android device that I mentioned above and using 2 pretty cheap Bluetooth dongles. One that I got from eBay and another that was laying around in the office.
thanks @jon . So finally after 8 months I started this thread, I have a answer : Someone use bluettoth with Mod Duo X and the last update! 
I’m happy to know that it works.
I didn’t try a factory reset of all my android devices. I could understand it doesn’t work with one android device, but with 3, and in fact 4 android devices because I tested another android tablet today, is it possible?
So do you consider this issue is caused by my Mod Duo X? And so what should I do?
You’re welcome.
Well…you never really asked the question directly if someone else uses the MOD DuoX with Bluetooth. You reported that in your case it was not working and asked for help. Also, 8 months ago the last update was another one 
That is indeed what makes it feel so strange to me. Possible it is. Unlikely as well. But maybe there’s a common app or settings that you are sharing between all devices that are messing up the system. That option to allow internet access not available looks really weird to me.
To be honest, I don’t consider that it is. But we are investigating.
@jon
I told that all my android devices where working in bluetooth with the Mod Duo just before I bought the Mod Duo X. Even my old nvidia tablet with a old modified android 4.
And since this date I regulary try bluetooth to see if things have changed.
@jon
I have something…
I just tried a third bluetoth dongle that I thought I have never test again, and tried to connect with my samsung S4 tablet.
Now I have the check box option to use internet with bluetooth device on the samsung tablet ! 
But when I check it it gives me a connection error “connection error, Activate Bluetooth modem on Mod Duo X3-0115”

I have been meaning to post here, but wanted to do some tests before hand.
Didnt do those tests yet, but just so you know, I am watching 
Only have 1 device I can test this with though, and it is quite the old android version (6).

I just tried this bluetooth dongle with my nvidia tablet with android v4 so your old android v6 shouldn’t be a problem. The result is different of what I get with the other bluetooth dongle, but I still can’t connect .
Traduction:
“connection error. Is the bluetooth connection shared on this device?”
It seams normal that your tablet detect an error connecting to internet, because there is no internet on the modDevice, so the tablet can’t ping the google servers (android does that to check the internet connection)
What happen if you cross “Accès internet” box and go to 192.168.50.1 ?

Well, no that’s not normal I couldn’t check this box.
All Android devices refuse me o check this box.
Again I’m not new with bluetooth and Mod Devices. I used bluetooth with my previous Mod Duo and it was perfectly working with all android devices I have at home. And since I have this Mod Duo X I can’t do the same, nothing have change except the Mod Devices product.
