Hello, 

I recently acquired a Code25 amp along with its footswitch (excellent for practising, great for gigs). 

One interesting feature is the Gateway app, however it doesn't seem to function with Android 9... making it useless. 

My device (latest version of Android 9) successfully finds the amp and pair with it, but the app doesn't display any connected Amp... even if the phone is literally ON the Amp. Nothing seems to correct this: tried resinstalling, repairing, etc. 

Is there anything to do here? Any fix? 

Thanks,

I need to find Marshall app on the play store store. It may have been broken who could help me find it. Thanks in advance!!!

1) Bought Code new, when released, USB port was loose and wont connect. Cant do Firmware or recording via USB. How to get service?

got at Guitar Center San Mateo Ca. When first released, hadn't ever really used USB, but realizzed it is messed up, like port is disconnected or broken. USB is wiggles and no connection. 

2) Cant get Gateway to Recognize tye Amp while BT stream audio okay. tried all steps from this site cleared phone and cache, removed and reinstalled, no diifference. Multiple versions of Android. 5 to 8.

Thanks,

James

I upload android version from ver.8 to Ver.9.   Gateway App worked on Android8. But it doesn't work on Android9.

Why? Can you give me the solution?

Hello everyone,...,,

I was wondering if you could help me with a problem that I am having between my Code 25 amplifier and the Gateway app. I am able to pair my android device and the amp via Bluetooth just fine but once I am in the Gateway app it doesn't detect my amp at all, even when I press "scan for amp" it just says no amp detected. 

I think I should add that I have been able to connect it to my apple device without any problem at all.

It would be highly appreciated if you got back to me.

Thank you......

I've had my Code amp for a couple of weeks and managed to connect it to my iPhone which is running the latest ios 10.2.1.  I also got it to connect to a brand new Samsung Galaxy Tab A running Android 6.0.1.  The connection didn't always work and sometimes dropped out.  I've updated the Amp to the latest firmware to hopefully cure the connection issues and now my phone and tablet just can't detect the amp at all.  I've tried turning on and off, resetting everything, forgetting the device etc. etc. but it's like the amp just doesn't have Bluetooth.  As no device can see the amp then Gateway just isn't possible to use as it also can't detect a phone or tablet. My devices can see each other but it's like the Amp just doesn't have Bluetooth.  I've also tried searching for it with an Ipad but this also couldn't see the Amp ?  It looks like the Bluetooth has died on the Amp but thought I'd ask if anyone has any ideas of anything to try or otherwise I'll have to take it back to the dealer and either try another one or replace it with a Fender Mustang.  It's a good amp but seems to have to many glitches at the moment looking at the forums.  I'll give it one more go though if anyone has any suggestions to try.  Any ideas anyone ? Many thanks for reading.

Hi there

I recently bought a code 25 and am inlove with the amp. One problem your app does not work on IOS. I have not tested it on android devices as I don't own any Android devices.

The app opens and everything but the sign in procedure does not work

Please fix your app!!

Hello,

I recently acquired a Marshall Code 25. I installed the last version of the app but, whenever I want to reproduce a song I have stored on my android phone, it crashes. It is consistent: it crashes all the time, to the point I was unable to playback a single song since I bought the amp.

Thanks in advance.

Hello, I have acquired the CODE 25, really an excellent amplifier, very versatile and very good presets. My problem and please I hope you help me to resorve it, is that even though I can connect via Bluetooth, I can listen to my tracks ....... the big problem is that when I want to use the FX or presets it appears that there is no amplifier connected ... (either from my android phone or my Ipad I ... I do not understand what the problem is.) Secondly, when I want to install the MARSHALL FIRMWARE UPDATE UTILITY, to enter presets or update the ampli, does not recognize the connection.I request guidance to be able to make full use of such a beautiful tool for my music.I use Widows 10 and G. Chrome.For your attention, thank you very much

I download the app open it and in a micro second it says "app keeps stopping" .pixel 2XL android ver 9. cleared cache etc re install , never works . have tons of space available on phone,,,,, so is there a list of phones that do or do not work ?

Where is the app on Google Play - it seems to be missing (8/23/18)

Even the link on your site is dead

Hello I just bought my CODE50. So first thing I wanted to do was connecting my phone to amp. I do everything from this site  https://my.marshall.com/support/faq/838/code---gateway-bluetooth-connection-troubleshooting but app still don't see code. I have Samsung Galaxy S7 edge. Please help 

Just got my CODE 100 2x12 and I can't seem to sync up the presets I've chosen on my PC, I'm using my Android device and sometimes they're there, sometimes incomplete, sometimes reverts back to factory. The android app seems faulty. If I hook the amp up to my PC will it always remember the library presets? I don't want to rely on PC or Android to remember my hard work.

The app is installed - it WILL NOT launch at all.

when I connect the app on android with the bluetooth amp and I want to load effects edited by other people, the effects return
by default, and when I deactivate the bluetooth again the edited effects appear in the library of the gateway app. Can not be
used when connected? I do not understand what happens.

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.

Hi there! I recently bought my code25 but when i try to download the app it says that my device is not compatible. I have a samsung galaxy A5. is there any known issue with this particular device? The mobile has all the requirements (latest updates, enough memory etc) and i also followed the steps posted on similar posts. Is there any way that i could get the app to download? Thank you in advance

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

Gateway does not work with my Android 4.4 phone. Does not even show the connect button for amp. Installed it directly to my phone 'cause Google Store says not compatible with my device. Did the "Fix" by remounting my SD and all steps but no luck.

Please assist with problem.
