the application does not recognize the code 25 amplifier, it only plays music, but I cannot control the effects.

It is quite easy to reorganise presets using the My Gateway webpage, which then syncs to the app. However, I like to keep my presets on the app and amp the same, and it is quite arduous to transfer them all manually, is there any way to transfer all presets from the app to the amp at once?

Yes, I've read the many questions of the same nature on the forum, and performed all the suggested actions. None of them have been successful.  I've seen many questions similar to mine, and only a few who have been able to make it work... and of those who did, their solutions didn't work for me.

When I connect my amp to my phone's bluetooth, it will pair for audio with no problems.  I can play audio through the amp.  When I open Gateway, there is no "red button" prompting me to connect.  When I tap on the CODE tab in the menu, it says "Not connected" and when I tap on the green "Scan for apps" button, nothing happens.

It will connect to my Samsung tablet with no issues.

Here are the steps I have tried:
Factory reset on the amp.
Unpair  and forget the amp in my phone's bluetooth settings.

Uninstall the app from my phone after clearing the cache and the data.

Update the firmware on the amp (the browser window said I was up to date but I installed the latest firmware anyway.)

What else can I do?  I don't want to return the amp because it sounds great, but not having the amp controls on my phone is a deal breaker.

Hi Marshall,
I am havin issues connecting my CODE 50 with my iPhone via Marshall Gatway app. Bluetooth connection is working and is connected with iPhone, but when I open app, app finds the CODE 50 amp and then it says "Connecting..." and nothing is going on. If I tap on my amp under Amps Detected, gives me this message: 
"Connection Rejected - You may only control amps you are already connected to for audio output".  Please help.

Hello !

I have a Code 50 and I use the Gateway to play, but it does'nt stay connected. For half an hour of playing,  I have to reconnect 4-5 times. Do you know why ?

(The Code is the only Bluetooth connection in my phone).

Thank you !

On the Gateway app I can playback very little music. I can easily play music with iTunes (Bluetooth) but I am referring to using the playback feature. I have tried to playback 50-60 songs, some of it is purchased but all of it is downloaded. Why do only certain songs work. This is a huge issue for me and one of the main reasons I bought the Code 100H and 212 cabinet. 

I have a Marshall Code 50 running MCU version 1.44 and Gateway (Android version 1.5.5) on a Samsung Galaxy S9+ running the latest OS. I can bluetooth pair to the amp and play music, but can not connect to the amp to change my presets from the library.  I have reloaded the latest firmware on the amp, deleted and reinstalled the Gateway app, paired and unpaired several times.  Nothing seems to work.  I even grabbed my old Galaxy S7 Edge phone and that Gateway app on it does the same thing.  Does my amp need to be serviced for Bluetooth connectivity?

Hi,

I have found a weird thing that may or may not be known with iOS + Bluetooth and the Code 50.

The CODE 50 when playing backing tracks / using it as a Bluetooth speaker is very quiet (So the master is wacked up and the playing guitar is extremely loud). 

and the weirdest thing (which physically makes sense but still it shouldn't do it) is that the Amp is predominatly a Left speaker when playing music through bluetooth as my phone (iPhone 6S) thinks my amp is bluetooth headphones rather than speaker (as the headphone icon pops up on the top right). 

My amp is on the latest firmware update.

Is there any fix for this? There's nothing in the gateway app for audio balencing

Just got my Marshall Code 25 and I'm pleased with the sounds, but there are a few presets that I will never use. Is there a way to delete either from the amp or through the phone app?

Dear Marshall-Team,

just bought a code 25. I wanted to pair the code 25 with my IPhone X and the gateway app, but it doesn´t work.

The Phone is connected to the code 25 via bluetooth, but the gateway app is installed successfully, but doesn´t recognise the code 25 to pair.

I´ve already tried all recommended troubleshootings without success.

Could you please give me any further help.

Thank you in advance.

Kind regards

Oliver

Hi all,

Along with a number of people on here it seems, I am having trouble with the Marshall Gateway App, which won't seem to connect to my Code 50 amp.

It worked first time round when I set it up, but now, a couple of weeks later, it won't connect. The phone says its connected and I can play music through it (when playing You Tube it comes out of the amp) but the gateway app says its not connected.

Unlike a few people on here, I can scan for amps and click the connect button, but with my phone sat on the amp, it just says 'connecting..." forever and ever and it doesn't. Why??!!

I've tried unconnecting and reconnecting the app on my phone as is recommended and switching the amp on and off but no joy.

Can anyone help and has anybody else had the same problem and managed to fix it?

Many thanks 

Craig 

Boa tarde pessoal.

Tenho o code 25 e ele não está conectando com o app Gateway. Ele conecta no blutooth do celular mas no app não. Alguém mais com esse problema? Se sim, como resolveram?

I have the Code 25, and just installed the latest updates (1.44) to the firmware. However, I still cannont get the Gateway app to recognize the amp. I am connected via blue tooth as I can play music from my Android phone over the amp, but the controls from the app don't work at all. Again, when I search it does not find an amp. Help? 

This is question about presets.

So there’s mymarshall presets and the app presets and then there’s the presets on my amp.

When I hookup my amp to the app all of the presets change to I guess updated presets that I did not program so I’m assuming they are just new presets from Marshall. Now there’s the iPhone icon and the amp icon. 99% sure they are all the same new updated presets. So how do I use the original ones that were on my amp and those? And do I have room to save the ones I download, without erasing the presets in the app or on my amp?

TL;DR why are there 2 different sets of presets when I connect the app and where do my original amp presets go / how do I use mymarshall presets without deleted presets

The Presets on my CODE 50 are different than what are on My Marshall site. I went to reset all Presets but it fails. If I try and Synch Now I get "Synch Failed". 

The App works (as in I am connected and can change settings, controls are GOLD etc). But my Library on the app is completely different than what is on my computer. 

Why is my Synch compeltely off? 

I am trying to import patches from my Marshall Code 100 amp to Code Editor using a cable and even after reinstalling Code Editor it comes up with an error message "Error While Decoding System : Error_Bad_Device_ID" whenever I try and import a patch from my amp from selected patch number. This is despite the midi light being green, indicating connection with the amp. This is after not having used Code Editor for ages like 6 or 7 months or so. I am sure I had it working at some stage like 7 months ago or so. Is there any other software you can use to transfer patches from my amp to my pc and save them as a backup? And even modify them like you can in code editor and Gateway?

I just received a Marshall Code 25 as a gift and I am new to guitar playing and using an amp. So I have 2 questions actually.

1. In the User Presets section, what does the X over the amp (code not available) exactly mean?

2. I managed to connect the bluetooth on my iphone with the amp, and it works fine, but everytime I turn my amp and the app on my phone on, my amp doesn't show in the amp. So I end up having to sync the bluetooth every single time I turn it on, let it search for my amp, and then I can get started. Is there some reason why my amp doesn't stay in the app?

i have try all the suggest from the support, re-install, re-boot, everything but nothing happens...someone has have same problems? and what have you done?

Tks a lot
