Dear Marshall team:

I use the Code 25 amplifier, with the Gateway app and the Code series footswitch. The firmware is updated with the latest version available.

For a long time I have been noticing certain problems, mainly:

-The preset settings are changed on their own (sometimes the volume, other times the gain...) They are usually changed to the settings on the control knobs. I load the preset again, and after a while some of the settings are changed again.

-Another problem is that after using a preset for a while, when changing to another it does not change (it stays blocked). It does not respond either by using the pedal or by changing the preset from the app I have to turn off the amp. At first I thought it would be a Bluetooth problem, since I was using the Gateway application, with an iPhone. But now I'm using it with an Android phone and I continue to have the same problems.

Waiting for your comments, receive a cordial greeting.

Eduardo,

The Gateway app on my Android phone has been repeatedly losing connetion to my CODE head in recent months, and attempts to manually reconnect have usually failed. This unreliability is completely unworkable for gigging, so today I have tried to solve the problem through a thorough update and reset ... but now I can't get the connection to work at all. I deleted the Gateway app from my phone, unpaired the phone from the head (by "forgetting" the Bluetooth pairing), and have installed all pending firmware updates. When doing those installations, I noticed that several related to improving Bluetooth operation, so I was hopeful this would solve my problems. So I've gone ahead and carried out the "First connection" instructions on the website, but these instructions have failed at a very early stage. After I press Rev and Power and get the blue flashing light, when I attempt to "Pair new device" from my phone, I get the message "No nearby Bluetooth devices were found". This connectivity problem is definitely at the Marshall end, because I have checked that my phone is able to connect with other Bluetooth devices and it is doing so fine, so the fault is not with the Bluetooth operation of my phone. It seems like there have been some known Bluetooth connectivity problems that you've tried to fix during recent firmware updates, so is this something you can advise me about and give me a fix for? I hope so - there's not much point in you having a really good product if it's unusable in practice.

Hi ! 

i was wondering, is it possible to use MIDI via a bluetooth connection ?

In fact i'd like to use a simple DAW application on my Android tablet to make some music using my Marshall Code. My Code amp connect to my tablet and the Gateway app runs nice, no problem. In the DAW app (which is for now BandLab), i see an option about a "Connected MIDI Devices" and my Code doesnt appear there. So i asked myself if the MIDI interface was really available with Bluetooth ? Or is there something special to configure or install ?

thanks in advance !

I turned on bluetooth on my  phone then initiated the bluetooth feature on my code100. find the amp in the It found the amp on my phone so I connected to it and the blue light on the amp quit flashing indicating that they are synced together. When I open the gateway app on my android phone (samsung S20E) it will not find the amp in the menu section of the app. I see the blue tooth symbol there with the word CODE next to it and it says not connected. There is nothing next to the Amps Detected: and when I scan for an amp it turns gray for a few seconds and then back to green. Same thing when i switch between the phone and amp icon in the bottom left corner. when on the phone icon i have presets when I switch to the amp Icon I get nothing displayed. I do have audio .from phone to amp and that s what it says in the blue tooth section in my phone. It says that the code V020150FDU connected for audio

I seem to be having the same issues that a lot of people have reported, where I cannot get the Marshall Gateway app to connect to my Code 25. I've only had the amp for about a week and I cannot get the app to see it. ? 

I can connect to the amp via Bluetooth using my phone (Samsung S10, Android 11) and whilst connected, can use it as a BT speaker to play music from Spotify. However, nothing I do seems to get the app to connect to the amplifier. 

-I've updated the amp to the latest firmware using my laptop/web browser. 
-I've followed all the instructions in the Bluetooth Connectivity Troubleshooter to the letter (CODE - Gateway Bluetooth Connection Troubleshooting - my.marshall.com)

No matter what I do, or what order I install/uninstall/connect, the app will not see the amplifier. Everything works otherwise - I'm able to apply Patches from ? using a USB connection - and the amp sounds great. I'd just like to be able to control it from my phone.

marshall gateway app is not working with android 11 version

the bluetooth connection is in place (blue light is in on) but opening the Gateway App the connection to the amp is not detected

can you please give me the info to solve the issue?

i've tried with another phone with android 10 sw version and the app is working

I think the app need some update to fix this bug (my version is 1.5.5 )

please consider that android 11 will be the standard for the most part of your code owner in the world

best regards

Salve! Non riesco a collegare il code 25 al sito My.marshall per provare i preset disponibili. L'appplicazione gateway si collega e la luce azzurra si blocca riconoscendo il Bluetooth.
Dal sito My.marshall mi dice codice non connesso.... anche se riesco ad usare l'applicazione Gateway e risulto connesso.
Qualche suggerimento? Sto usando Crome aggiornato con smartphone Android.
Grazie.

I have a samsung s10 and android 11 and I can successfuly connect my amp to my phone via bluetooth, but I can't connect it with the app, it just can't detect the amp.

I already re-installed and re-connected the app and amp. What can I do?

I have had a chance to spend a few days with the Marshall code 25 and I would like to share with you a few of my findings. I have played guitar professionally for over 30 years and have had all makes and models of guitars and amps in my time, but in general I would have killed for the equipment available to guitarist today.

This is the point where I look at the Code 25 and think “that looks like fun”. I have a few amps kicking about already, mostly gigging volume amps but I also have a Blackstar ID-Core 40, so this would be in reality what I would compare the Code 25 against.

Firstly my experience with the amp and a look around these forums makes one thing apparent. This amp is well named because it is a bit of an enigma.Out of the box I would consider the amplifier not fit for purpose this is really down to a few reasons.

Firstly, some of the presets are just absolutely terrible, I mean some of the worst patches I’ve ever heard on anything, “Small combo” and the “Brit” overdrive amps for instance are shockingly bad. You can make the excuse that all amp and effects units come with bad presets. However this is usually down to strange or weird effects to give bizarre sounds to show off effects but that nobody would ever use in a musical context. However some patches (such as Small Combo) are just basic amp modelling with no effects and are still absolutely terrible. Maybe these sound better on the 50 or 100, but if that’s the case remove them from the 25 it just gives a bad impression.

Secondly, the amp is stupidly loud. I don’t know if this is a marketing decision, but Marshall should look at its target demographic. This thing is a small bedroom practice amp, maybe at a push for some very small live situations, but that is it. Why make the thing so loud? If you need to use this amp near anything over half volume you have bought the wrong amp it’s as simple as that.

Thirdly, some of the modelling is not all it could be with digital artefacts (in the low end in particular), and a fizzy noise gate that for some reason is on patches where there is absolutely no need to have it as the patch is pretty quiet. Once again this is not a professional gigging or recording product and it should be judgged accordingly.

The last bad point I would say against this amp is the tuner, both onboard and on the app are two of the least responsive and wildly inaccurate tuners I have ever seen. Really not even close to tune! Put this down to another marketing tick box.

OK, now the good points.

It seems pretty well made and solid for what it is.

I like the size and weight, ideal for a bedroom practice amp.

I like the complete range of controls on the amp, and how you can do everything on the amp that you can do on the app, and it’s easy to do. Great user interface design work.

I like the Bluetooth features and the app. I know people have had problems with Bluetooth, but both my IOS and Android phones connected right away and are stable. I can stream music no problem from outside the house or in other rooms with no issues.

I like having 100 presets to store all the patches I could want (My Blackstar only had 6, and you can only have 1 for each model).

The headphone socket sounds OK, but if I wanted that as a primary feature I would have just bought headphone amp with effects.

I don’t use the recording over USB feature. If I did I wouldn’t expect something this cheap to be amazing. Once again if you want this you probably have bought the wrong product, and are in the wrong price bracket.

I like the cost, its amazing what it does for the money.

I like the sounds, now that I’ve got rid of the awful ones.

It looks pretty cool.

It’s a Marshall.

To make this amp useable, I basically had to do the following:

1. Delete all those terrible patches that are just filler and basically just give the user a bad experience. After doing this I was left with around 20 good sounding patches and 20 OK patches, the other 60 I replaced with a patch called “Blank” (which I have put up on this site). That way every patch sound good to me.
2. I turned the Mater volume up to ¼ (around 9 o’clock)  and went through the remaining patches adjusting the patch volume of each to make it a sensible volume for bedroom levels. This ranged from around 0.3 to 5 for most patches depending on the patch. This means that you have more control over the master volume and can change patches without is suddenly blowing you head off. There is still plent of volume in the amp after doing this. OK I admit if I want to use headphones I have to turn the master up around half way, but that’s no big deal. Likewise as I said I don’t use the USB for recording, but I assume I would have to turn up the volume for that too. I don’t see that as a problem either for a product in this price range.

Overall I like the amp and doing just these 2 thing make it much more of a pleasure to use. The volume level are more what they should be for a product of this type and I don’t ever hear any of the awful patches (there are plenty of good ones).

Maybe other people can share their first experiences or tips with the Code 25?

I've recently purchased CODE 25, installed Marshall Gateway, and paired the code 25 with my smartphone (Xiaomi Redmi Note 8 Pro, MIUI 12, Android 10).

All was fine, I've listened to some pre-sets using the application and tried to disconnect the CODE 25 from the phone. I've opened the Bluetooth settings on my phone, tapped to the CODE 25 device, and pressed to the "unpair" option.

BUT the CODE 25 still tries to pair with my phone every time, when the Bluetooth is on.

I've tried to reset the CODE 25 to the Factory settings, tried to update the firmware - no result. 

Not even resetting the Bluetooth settings on my phone helped to solve the problem: the CODE 25 spams my phone with the requests of pairing every time I turn the device on.
When I pressing the Cancel button on the pairing request, the next request comes within several seconds.

It's really annoying!

How to force the CODE 25 to stop spamming my phone?

Hello,

Gateway works  without problems on my Code 50 Amp up to yesterday 06th October 2020!

Amp is not often used, bought new on November 2018. Also checked  for the latest update for this Amp on 06th October 2020.

Android Device is Samsung Galaxy S8, version 9, latest update 01st September 2020.

Several times i have again and again downloaded the Gateway App en have several times tried to get bluetooth connection between Amp with device and between device and Amp.  Bluetooth connection between Amp and Device no problem. Is connected for streaming audio to the Amp. But no succesfull to connect App with the Amp. Tried over and over conform all the instructions on the Marshallwebsite /troubleshoooting.

Very, very strange that App is not working anymore!

 Who can give me the solution to solve this very strange problem which give me headaches?

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,

My Code 25 cannot communicate with my phone via Marshall Gateway. The software cannot find and connect to the amplifier as if there was no bluetooth connectivity, but there is as I can listening to music via that. I use Galaxy A5 android.

Could you help me to solve the problem?

Thanks

Adam

Hi guys,

Thought I'd share what finally worked for me to get my CODE amp to connect to the gateway app.

I had tried literally everything, unpaired the amp, reinstalled gateway about 10,000 times, used 3 different devices. All with no success.

Until I tried this:

This worked for a Samsung Galaxy S2 tablet, but I suspect it would probably work with any device.

1. Uninstall gateway from your device

2. Unpair every single device you have paired with your device through your bluetooth settings.

3. Clear your bluetooth cache and data. On an Android device this is located in App Manager/System apps (to show system apps you might have to click the 3-dot symbol on top right of settings screen)/Bluetooth/Clear cache and data

4. Restart your device

5. Re-Install Gateway app

6. Pair AMP with device via bluetooth

7. Open Gateway app, and hopefully, you'll see your CODE amp has finally connected.

The key here is to unpair all bluetooth devices and clear bluetooth cache through your phone's settings.

Credit to Cris Lebrun who shared this solution elsewhere in the forum. It was kinda hidden so I thought i'd make a separate thread for it.

Good luck

Hello everyone,,

My marshall code 25 connects to the  bluetooth of my phone (Huawei Y6II Android 7) but the gateway application does not detect it and does not connect it.

Thanks

Hi!

Please help me, Marshall.

I can't connect Marshall Gateway version 1.4.9 running on my cell phone Moto Z Play with Android version 8.0.0 to my Marshall Code 25. The button "Scan for Amps" does not work. Even if I click "Auto-connect" option it does not work too.

I've tried all the solutions on https://my.marshall.com/support/faq/838/code---gateway-bluetooth-connection-troubleshooting without success.

The Bluetooth on my cell phone is on and Code is paired with Marshall Gateway.

Look at the screenshots.

Kindest regards,

Fábio

I'm brand new to the forum and I'm here because I have a problem. I bought my CODE 50 about a month ago -- love the amp by the way -- and it's been connected to my Android smart phone ever since I first set it up. I have the auto connect feature enabled so whenever I've been out of range, then moved back into range, it reconnects automatically.

Well, it's worked normally until this morning, when I noticed that nothing was happening when I was changing some settings using my phone. Come to discover the pairing had been lost. At first I started to retry pairing from the phone's menu, where it showed the CODE 50, but it didn't show it as being connected. When I put the amp in pairing mode, it had no effect in the app. 

So I exited the app and booted the pairing function in the phone. The phone paired with the amp quickly, showing the amp's code. But when I went back into the app, now it doesn't even show the amp anymore and when I hit the scan button down in the bottom left of the screen, the app just sits there and doesn't do anything. I've tried restarting the app, but that doesn't do any good. It just comes right back to the same screen as before. 

So, what now? I'm thinking about uninstalling and reinstalling the app, cuz I can't think of anything else that might work.
