Like apparently everyone else, my Code 25 "forgets" to turn on Bluetooth, and I have to restart the pairing process all over again, everytime I want to play.  I have to delete the pairing from my phone, turn on bluetooth pairing on the amp,  and rediscover the amp.  EVERY FREAKING TIME.  Where's that update to the firmware?

Is it possible to control and make changes to the existing preloaded patches of the Code App via the USB port connected to a Windows 10 Laptop?

or the Marshall Gateway App works only with Android/iPhone via Bluetooth?

thanks

Hi,

I recently purchased a Code 50 and have been trying to connect it to the gateway app on my Android phone. The phone connects to the amp successfully via bluetooth and I can stream the audio out to the amp directly using Spotify but when I go into the gateway app, it says "Not Connected". I tried the "Scan for Amps" button but it doesn't find anything. Any help is appreciated.

I bought the Code 50 a week ago and haven't had any luck getting the blue light to come on when holding the rev & power buttons. The screen says "bluetooth pairing enabled"..... But there's no blue light.

Hola,

Compre un code 100h recientemente y realice la conexión vía Bluetooth, pero genera un ruido como un pitido muy molesto, ya realice la actualización del firmware pero continúa, realice un cambio de ubicación para descartar interferencias y revise polaridad de las tomacorrientes, pero aún se mantiene el pitido, alguien me puede ayudar ¿..?

Gracias

I guess with Marshall being a small company without much expertise in building amps, this should be expected.  Maybe once they've been around a while and get the hang of building amps then they'll be able to release products that work as advertised and that they are also able to maintain and provide support for.

Hang in there Marshall, you'll be a good amp company someday!

I have successfully synced some presets onto the Gateway App on my phone and can use them when my phone is connected to my Code 50 amp via bluetooth. Is there anyway to overwrite the presets on the amp with presets on the Gateway app, so those presets are available without connecting to my phone? Thanks!

I connected my Code 50 to my laptop via bluetooth, but the my.marshall presets says "CODE not connected". I tried connecting via USB, but the amp has a goofy connector that standard USB cables do not connect to. Also - I can connect via the Gateway app on my phone, but the presets I add to My Library do not show up (even though it says that they have synced). 

I have connected several devices via bluetooth to code 50, but it did not manage to  synchronize whit the app.

Help... 

I'm connected through bluetooth to my code 50 and i can choose to change the different presets, but when i go to edit the presets of gain, bass, treble, volme etc etc, nothing hapens. Am i missing something? Even that little button the shows phone to amp or amp to phone in the bottom left corner does nothing.

cheers

After I power off the CODE 25 and power it on again, it doesn't start Bluetooth connection automatically (there's no blue light) and I have to press 'rev+power' and perform pairing every time. It looks like the amp just doesn't store bluetooth connection configuration?

So for every guitar session I have to start bluetooth manually and re-pair the device which is not convenient.

Could you please give a possibility to downgrade the firmware? I've read that bluetooth auto-connection was working fine on previous version.

Hi I have had this Marshall Code 100 for a few weeks now, mucking around with it to try and figure it out and finding it to be a little user unfriendly. What I want to do is to change a single preset to what it was originally (eg factory setting) without doing a factory reset and losing all my other changed presets. I cannot find any joy anywhere about this. Also, when I look at the list of 100 presets online (there are a few lists going around in chat forums and also in the gateway section of this website) I can only ever find the 100 presets that are on the phone gateway app and not the list that was originally on the amp (for example on my amp when I factory reset it, 00 is JTM Chill, 01 is "So American" etc, whereas my gateway library has 00 as EL34 Heaven and 01 as Plexi Classic). So I cannot find the actual standard amp preset list anywhere online or within the Gateway app.

My questions boil down to three:

1. How do I restore an individual preset to what it originally was (without performing a factory reset)? 

2. How do I even know what the original preset was called?

3. Say I connect my smartphone to the amp via gateway and bluetooth. If you click on the arrow on the right hand side of one of the presets in the library, it takes you to another screen. In that screen it has an amp section and a library section, with 2 small boxes you can tick next to each. What is the purpose of this screen and ticking the boxes? Like what can you actually change on this screen is it just the name of the preset or can you replace a preset that is on the amp with one that is in the gateway library?

Needless to say I am very confused and was hoping to be way ahead by this stage. Please help!

Does anybody know when Code firmware update is expected to be released?

Current version causes serious issues with Bluetooth reconnecion after the amp is swiched off.  Also Master Volume does not work evenly and my CODE 25 is definitely too loud for practising at home.

I have purchased new Code 100 (a demo from Sweetwater)  I am not able to connect the amp to my personal device.  When I press the Rev and Power buttons to connect,  the blue lights flash,  the device number shows up on the amp but either of my devices (an I Pad and an I Phone) will not recognize the Code amp.  The Code Amp does not show up in the "My Devices" so it never has the opportunity to pair or show up as connected .   My phone and Iphone recognizes other bluetooth items, ie, head phones, speakers etc. I have tried the FAQ suggestions and have tried the recommended fixes and I am still not able to connect.  

I have not done a firmware update on the Code 100.

Any assistance would be greatly appreciated.

Thank you,

It seems that my phone is connected via Bluetooth,

but on my iphone SE I do not see a connect block on the Gateway

only  a scan for amps block and this does not do anything.

Help

So I bought a Marshall CODE 50 a bit ago, and with nearly device I've tried - there seems to be a lot of issues with getting the gateway app to connect to the amplifier in general (most of the time it doesn't work - despite pairing just fine). 

I've tried this on the Samsung Galaxy S8, iPad 5th generation, iPhone 7+ - The connection issues seem to stem from the apps use of Btle on these devices. 

To experiment, I built an application that connects to the amplifier via bluetooth for Windows, and issues commands to the amplifier through the PC. This application uses a "classic" (SPP /RFCOMM) socket connection to send commands. The application works perfectly fine via this means - it can be seen running below: 

As an experiment - is there a way to force the mobile applications (if it isn't using a btclassic / rfcomm connection) to use a btclassic connection as opposed to btle? 

Thanks and all the best,

Hello. I just bought a code 50, and been trying to connect the Bluetooth but it simply doesn´t work. No Code50 is found in the list.
I have a Sony Xperia L, with the newest Android version (7+), but i can´t download the Marshall Gateway App from the Play Store, cause it says it´s not compatible with my Android version. 

I´ve read the forums, and more people seem to have the same problem. Please FIX so i can try using the full potential of my amp...

Hi, my Code 50 USB has stopped working, nothing wrong with the USB port because it still charges the phone - tried two cables, no luck.  So now I'm trying to figure out how to play songs through it via Bluetooth but *&^%%%%### no luck - how the hell do you do it? I've downloaded the Marshall Gateway app to my android but all i get is my phone icon and an arrow to the amp icon. DO I have to do something on the amp?
