I am having a problem when I am using bluetooth on my ipad the gateway app will freeze right in the middle of editing a preset. I am not sure if it is a bug or if its my device, but ive tried reconnecting the bluetooth for my amp and gotten the most recent update. So if someone can help me out that would be awesome.

Is there a firmware update due to be published? Many users have the same problem, either with establishing a connection or having the connection retained. In my case it's having the connection retained after shutting down. As I have said in other comments it's not a big deal resetting my Bluetooth on the phone and I simply do it now becasue it's become part of my process. This doesn't change the fact that I shouldn't have to do it once the connection is made. So based on my basic troubleshooting I think the issue is the last firmware update. I request that the programmers have a look to see if there is a problem in the Bluetooth coding. I think it is fair to say that we all really like the product and the tones we get. But the selling point is the Bluetooth and the remote interface this allows. Just for interests sake... is the firmware written by Marshall or somewhere off shore?

Bletchley is famous for cracking codes. Let's keep the tradition going.

Regards.

This amp sounds nice, and I really want to play with the tones, but I lack a compatible phone for it. I have an LG stylo2,  but I also have two macbooks, an imac, and hackintosh. I even got the bluetooth to work on the hackintosh. The play store keeps giving me the error that "my device is not compatible with the software." Followed the instructions to get it on, but to no avail. So, I'm stuck hoping that Marshall gets the message and develops some iOS software for this thing. So, what do you say?

I timed it.

I’m not looking for trouble, im just looking for customer service.  I’ve got far better use for my time then sitting on this forum, trolling for answers that will never come—unless YOU, Marshall Amplification changes, which is highly unlikely. You guys are going to be getting a very brutally cold visit from me at the NAMM show!

After going through the entire Blootooth connection process again, which takes like anywhere from 5-10 minutes to get connected, I went to the MyMarshall.com website to download some of the interesting amp models which other users have taken their time to create (thank you to all who have fond this!)  When I download, it goes to my actual login like it’s supposed to, but how do I get it from the mobile device to the amp?  Your video isn’t clear, but do I have to have my device connected to the USB of the amp?  If so, when is the frigging purpose of having Bluetooth then?  If not, what am I doing wrong?

I await for your robotic response.  I’m sure I’ll still be right where I’m at after it comes!

I made this comment in response to another query and thought it would useful as part of the general forum...

Been following the comments about Bluetooth for a couple of weeks since I have been having the same problem. What I discovered is that the problem is not the amp but my phone. For all intents and purposes, the amp is just a dumb device that happens to have a Bluetooth connectivity board or circuit built into it. The primary connection device is the users phone, tablet, whatever that has the Bluetooth application. Anyone using a Bluetooth speaker should know and understand that the speaker has no application, just an ON/OFF switch and a Bluetooth circuit. It's the phone that makes the connection. So in my case, it was the phone that dropped or lost the connection to the amp. There was no way I could reconnect, even after shutting everything down and rebooting. Going through the Gateway app on my phone wouldn't work and the blue light on the amp would blink continually.

What I then tried was turning off my Bluetooth on the phone, reactivating, and getting the app to pair up again to the amp. Problem solved.

It's possible that all the wi-fi items I have in the house and garage are confusing the phone and Bluetooth but I haven't troubleshooted that as yet. I have found a simple work-around that, I agree, is less than ideal but gets me using the amp the way I want. I don't disagree with what users are saying but I also think that not every fault lies with the supplier. Perhaps a reasonable challenge to us users would be... if any musician is a programmer or electrical engineer then offer some assistance. I have yet to find any innovator who can design for every nuance we currently experience in this tech world. Also if anyone has another, better work-around then please submit to this forum.
Regards,

Marshall Support,

Your copy/paste response to everyone is unacceptable!

You know damn well that most bought this amp online! There is no talking it back to the dealer, other then sending it back for a refund!

I hope others agree with me here that the customer Support for this amp is HORRIBLE, if not worse, nothing compared to the REAL Marshall reputation!

We all have the same trouble with Bluetooth. When one ends their session, turns the amp off and shuts down the app, it is impossible to reconnect again without having to delete in your device’s Bluetooth connection to the amp, then going back to the amp to Pair again.

The problem is YOUR programming and design. This amp is great sounding when standing alone, working the controls on the amp itself, but try using a mobile device or tablet, and it’s failure as an amp is evident! This could be simply remedied with the design of a new application and updated, new programming of the amp. Instead, you continue to reply the same thing over and over again!

i ask every Code 25 owner here, am I wrong?!?

I bought this Amp because i play different Marshall Amps for over 20 Years now.

The sound is great, but there is always an issue trying to connect my phone with the amp via Bluetooth.

The Amp is in pairing mode, an I tried different Android phones (old ones and the newest), even my
band mates tried a connection. The Amp never disappears on any phone we tried.
Even my Laptop does not even find the Amp.

I tried the firmware update to 1.41, also rebooting, all the things mentioned here in the forum
and in the troubleshooting sections. Nothing works.

I am disappointed, this is not what Marshall stands for!

Ive had this amp five days now and I’m totally frustrated!

Here are my issues:

• Bluetooth Connectivity

The amp loses connectivity with the MyMarshall app constantly!  I’ve followed the instructions.  I’m sitting less then a foot from the amp, yet it loses connectivity from both my iPhone and two different iPads.  It literally takes me 15-20 minutes to get the thing connected, reconnected, and then, BOOM! Again, the sound changes settings on the amp mysteriously, this after taking 15-20 minutes to get the sound and effects exactly the way I want it.  I can’t save the setting, because it disconnects the app from the amp, even though it says on the amp and my iPad settings, that I’m still connected.  Utterly frustrating! It also limits what time I have to practice because I’m spending most of that time trying to get it reconnected and sounding right again.

Also, after following the directions explicitly, I still have to  reconnect the Bluetooth from scratch every time.  The app sucks.

• Apple OSX /iOS compatibility

Guys, Your the best amp manufacturer in the music world.  The music world is OSX/iOS based. Get your brilliant minds together and allow for the amp to be Updated via Apple products!

• The amp and application

This is a great sounding amp, I’m enamored with the sound as I am with most Marshall Amplification products and the price well within reason, but not just the app is HORRIBLE, but also the effects are also less then desirable.  I just can’t seem to get chorus, phase, flanger or echo sounds to my tastes and desires.  Same with the auto wah.  I just can’t believe you can’t duplicate the same great sounding effects as you have in many of your solid state amps.  

I’m hoping you can help, if not, this amp is going back in the box and being returned.

How to connect Marshal Code 25 via bluetooth to Android

Actualy my first try is on Samsung S5 Neo and they did not working 

I try My Asus tablet Android 7 and thy connected with no problem Marshall Gateway working fantasticly good

ive got the app downloaded, Bluetooth connected, but playback doesn’t seem to work out of my iTunes library.  Also, directions how to operate the delay and modulation effects.

Any help much appreciated!

hi

firstly, i am disappointed with the code.  this amp seems like its still at test phase, its to buggy for a release.  would expect marshall to only release a new product unless its 100% reliable.

connecting ios devices to code is always problematic. very unstable.

my main problem now is updating firmware.  cant update in chrome. i have midi capability approved for marshall but keep getting midid disabled error even though i clearly have midi enabled.

tried opera, and the midi is working and the code is coming up as connected. i get as far as a message stating that firmware is updating with a status bar and percentage marker. doesnt update! stays at 0% and never moves. left it overnight and still 0% when i woke.

i have spent more time messing about with the problems with this amp than playing guitar. do i need to sell this and just buy a guitar interface? maybe

also, when using this amp through garageband there is no dedicated clean preset to use with garageband or other AU. basically it goes into garageband with a marshall preset and then the other AU preset is on top of the marshall preset. ideally this amp should include a straight clean unprocessed preset to work with other software AU's.  i really do think people need to consider a good quality guitar interface before purchasing this amp. its very restricitve and unreliable. if you are not gigginG i dont see the point in this amp. 

CAN SOMEONE HELP ME WITH THE FIRMWARE ISSUE ASAP!

Can I connect to my code 25 via USB to my RCA Voyager tablet cause I can't Bluetooth to work

Sorry for my english, i´m from Argentina.
Thank´s

Greetings, 

I recieved my Code 100H this week.

Firmware:

(FYI) I attempted the update with a MacBook Pro with USB-C, High Sierra 10.13.1, Chrome Browser. I was able to connect to the Code but the unit would not update. It was stalled on the progress bar on the unit at 0% and on the browser. 

(FYI) I attempted the update on a Windows machine and was successful using the update utility and with Chrome Browser. The Code unit shows updating to 1.4.1 but the boot screen shows 1.11?

Bluetooth:

The Code 100H will not connect to any Bluetooth device I have. Windows, Mac, iPhone, or iPad. It does not even show up as a device and never has even out of the box. I am convienced it does not work. Is there a master reset button combo for the unit? I am out of ideas concerning the Bluetooth. It seems like I am not the only one having issues with the Bluetooth. If this can't work consistently I am considering returning the unit. Even the simplest device can connect with Bluetooth and hold a connection. My Code 100H won't even show up as a device to connect to. Please advise. 

I am having issues every time trying to connect my 100 head to my ipad.

frustrating.

i have connect my phone whit the amp code 50

but in de gataway app i see the code 50 but when i press connect he sais not connected 

so i dont work what is the problem

well, it seems quite odd connect the amp with the app.

I'm able to pair my amp correctly and play music through it but it is nearly impossible to connect within the app. I said 'almost' impossible because for a few times it happened.

I can't explain, sometimes the pair/unpair process or the remove/reinstall the app or both, but it's painful and annoying. It isn't properly plug & play. 

Also I tried to clear the bluetooth cache, the app cache, disabling wifi .... get out the dog..

Do something, please.

Massimo

my Code 100 head arrived 2 days ago and I still can't get connected via Bluetooth with either iPad or iPhone.... Very Frustrating if this continues I will return this piece of S..t it did connect once but Never again!!!!!!! What's Up With That!!!!

Code 50 setting up bluetooth connection and when I use my iphone or ipad to pair the iphone/ipad asks for a 6 figure number to be seen on the code 50. problem nothing shows, have spent ages trying closing down phone ipad amp etc
