Suddenly, Bluetooth stopped working right on my phone (Huawei P series)  while I'm playing...  Amp is updated to latest version and every time i want to change preset surprise! The phone is unpaired, it needs to reconnect again... but guess what? Now the screen on my code start blinking, not red or the buttons either, but it blinks like if loosing power or something... I don't know if it might be an electrical issue or it's just a lose cable inside that needs a check. 

I recently got a Code 50. After a few weeks of using it and learning the my.Marshall website, I realized it did not have any of the newer firmware updates. I updated it with v. 1.47 and now I do not get any guitar sound. I get sound from my phone when it's connected via bluetooth. How can I install the previous version of firmware?

I tried using the foot peddle cable to see if it is a cable issue and strange things happened. I hear some strange music broadcast. Not sure if some neighboring device connected to my amp via bluetooth. Is there any way to turn bluetooth off and on?

I tried doing the factory reset and it does not reset the firmware. Is it supposed to reset the firmware with the factory reset function?

Thanks.

UPDATE: I got this resolved. It turned out to be an issue with the guitar.

Gateway version 1.5.5 (Wireless Bluetooth selection from the set list, playback selection)
I bought CODE 25 because of its services.
This wasn't made for a concert, but it was great for practice. It took a lot of work to set up the sounds and I was able to play music to my liking with the help of my mobile phone. Now, against my will, version 2 is here, which does not know these things. It was difficult to download the 1.5.5 version again because I like it, but the next day I have the 2nd version on my phone again and this has happened several times. What right do they have to overwrite my phone's settings?
How could I use my favorite amp and settings again to my heart's content, because that's what I paid for, I worked for. If there is a new version, anyone who likes it can use it, but why prevent those who like the old version from continuing to use the system that was created with a lot of effort. This is why I can't return the amplifier! I am waiting for an urgent reply!

Buenas tardes, el día de hoy actualicé mi aplicación gateway y también mi amplificador code 25 mediante USB. Lamentablemente al tratar de cambiar de preset a un preset guardado desde la app se desconecta el Bluetooth.

Por favor, necesito una solución! 

Hi, 

i just bought my first electric guitar and amp (Code 25). I'have maneged to use my headphones via bluetooth to play. Now i'm trying to record something. So i connected my amp via usb to my pc but i have to use the headphones with cable which is super annoying. Can someone help me? 

Thank you in advance,

Ivan

where dso I find the passcode for bluetooth?

Gateway app is synched and connected to CODE 50 via bluetooth.  Not sure how to call up the presets from my library, to the amp?

Quelqu'un pourrait il m'aider s'il vous plaît je n'arrive pas à connecter mon ampli code 50 sur l'application Marshall gateway il me met ce message: CONNECTION REJECTED You may only control amps you are already connected to for audio output.

Je précise je suis sur iPhone 13 dernière version d'iOS.  Le téléphone lui se connecte sans problème à l'ampli je peux joué de la musique mais c'est tout 

j'ai au préalablement supprimer et réinstallé l'application gateway, reset l'ampli, mis à jour le firmware de l'ampli, déconnecté l'ampli du téléphone et oublier l'appareil Bluetooth, essayer sur un autre iPhone (7)... bref je suis perdu du coup je ne peut en aucun cas faire mes préset depuis mon téléphone et c'est frustrant enfin bref si quelqu'un a une solution miracle je suis preneur et merci d'avance 👌💪

Omg my code 50 as just completely lost any sound no Bluetooth, no headphones, no amp what the flip is going on I've updated firmware hundred times reset amp hundred times and nothing dead as a door nail all lights and functions on amp work OK just no sound please please please help.

I am having difficulty getting my Code 50 to connect via bluetooth so I can transfer presets that I like to the amplifier. A forum post response suggested that opening a new page in Chrome and inserting "chrome://flags/#use-winrt-midi-api" will do the trick. I tried on both a Windows 10 and Windows 11 machine and nothing came up. I also searhed inside the new page and it came up empty. Is there another way to do this, or am I doing something wrong?

Bluetooth подключён к Code 25, но Gateway не видит его

I have tried to do this and the CODE 50 does not appear on my device list in my ASUS Laptop with Windows 10. Is there a workaround?

Hi folks,

Reently got myself a CODE25, however I couldn't manage to get it connected to my phone. I assume its due to faulty bluetooth module, because when I turned on the amp, bluetooth version field is missing on the screen. The amp also did not show up on my phone although bluetooth pairing mode was activated.

I did follow the troubleshooter but it didn't help.

Updated to the latest firmware (1.46)

Anyone experiencing the same? Any suggestion how to fix this?

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

This issue is driving me crazy. My Code 50 used to work with my iphone and ipad, now it refuses to connect and I always get the above message.

I have performed the following:

1. Forgot bluetooth connection on both devices

2. Deleted iphone app and re-installed.

3. Re-paired and tried to connect with same issues,

4. Formed factor preset of amp with no luck.

I know the blueotth connects as I can play music through my amp from phone, I just cannot connect to update any presets.

Any solutions would be greatfully received, am getting so frustrated with this product.

Hi guys,

i have a marshall code 25 and i have a problem when i link my phone via bluetooth and via jack to have a backing track while i'm playing guitar.

via bluetooth the sound is like in a shell, is not clear and brilliant, but like closed, sorry i can't explain well. Like the treble very low, and the middle and bass high

via jack in the ipod input i need to raise the master volume to the top to hear something but is very low.

A friend has a marshall 15watt without bluetooth but with the ipod input. When i link the phone there, the sound is not affected by the master volume but only by the phone. And the sound is good like directly from the phone. The pots on the amp changes only the sound from guitar like normal use.

What can i do? Could you help me?

Thanks!

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.

I just bought the code 25, and only had it for a few days.  It was great on my iPad for effects via bluetooth, although after  I updated the firware it wont connect to thre app on my ipad anymore, it plays songs from my itunes app but the Gateway app says Im already connected and nothing works to adjust the affects. Im really bummed about this, any word on why this is happening and how to fix it?.
