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?

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? 

Cant pair my code 25 and all phones in the house on the android (sumsung a70, lenovo a1000, micromax q385, sony xperia xa2 plus and others).
In the bluetooth settings, phones do not display the device name but its mac addres: "С8:DF:84:26:58:1F".
When pairing some phones it asks for a PIN code, the rest are not connected. In any case does not connect. 

*****UPDATE :  PROBLEM SOLVED.  OR MORE CORRECTLY, NO PROBLEM TO BEGIN WITH.  APPARENTLY THIS IS NORMAL AS ALL OF THE PRESETS HAVE BEEN SAVED TO MY AMP.   NO REPLIES NECESSARY. THANKS! ****

Hello all,

I'm a new Code 50 owner and am just getting started.  I bought mine used from Guitar Center so I don't have the manual at hand and am running into an issue.    I have added a ton of user created presets to my library on the gateway page, and synched them to my android app.  When the app is connected to the amp I can see the presets when in gateway mode (blue dials).   

Here's the problem I'm having:  When I try to save the preset to the amp, I open the preset in the library, click on the arrow to the right, and put an x in the amp box.  When I click save however, the amp box unchecks and I'm back where I started.  

I'm not sure if this is a glitch or I'm missing a step somewhere.  Can anyone help me out?

Thanks much!

Mitch

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

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

after correctly updating the CODE AMP and the Gateway, the connection is still wrong, I had hope with the last update but it has not helped me at all.

he version of android that I use is ANDROID 9, with the phone Galaxy J6 + ..... I do not understand where the problem may be.

I would appreciate Marshall's help in correcting this problem, they have already contacted me for a long time but the guidelines were erroneous from the beginning.

Thanks for all.

I just bought a Marshall Code100C from the Sweetwater sale.

Anyways I have 2 older Amdroid phone and NONE can get the Code Gateway App.

But my Newest LG Android phone can download the Marshall Gateway App and install it.

Problem is when I turn on the Code 100C and Turn on The Gateway App on my Android phone

it does NOT find the Marshall 100C and I downloaded the Newest Firmware for the Marshall 100C.

What can be my problem?.Thanks allllll....JT

On my Android device Samsung Galaxy 8+, Software version G955USQU5DSDA.  The Gateway crashes whenever I attempt to import music.

On my iPad Pro  (9.7-inch), Software version 12.3.1,  The Gateway refuses to load music.

Any help, clarification, or a suggestion of a solution, (is there a particular program that works well to assist the import of music into this app on either platform)? 

I also have a PC running WIndows 10 Pro x64, with an i7 and 32GB of RAM, is there any work around involving any particular DAW that allows this?

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

I really like it when I get it working. I had to utilize an old Android Sony Xperia phone to get Gateway to connect to my amp.

I found problems wtih the Sammsung J7, S7 and S9 phones that I prefer to use.

As I have a solution, I am not livid, but I do think your support is dodging the issues with Gateway. Hire someone from the SF Bay Area to remake the Application. I am sure you can find a slew of capable programmers. Just contract someone and fire your inhouse programmer(s) as they have let you, no they let your Users down.

First pairing is OK but after a restart NEVER the Blue Light goes on and, its clear,  no auto reconnect.What is the Problem?Please Fix It!

I use iphone 6s ,  ipad Air,  Samsung J5 and a old Samsung Node.NO Device works. (Android and iOS)

From my Point of View the Code 25 is the Problem not the Devices, because Bluetooth goes not ON if you turn the Code ON.

Please ask me its a Bug and you can FIX it with a new Bluetoot Version or is a Hardware Problem and you cant fix it.

Many Customers waiting for a Fix over 1 Year!!!!

I have the Code 25 just one Day and update the newest FW via Crome with my Mac.

If you cant fix the Problem i send the Amp back to the Dealer in Germany and get my Money Back.

I have a lot Amps from Marshall (like Slash Sounds) but this is a shame.

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,

Hey, Marshall! I connect my iPhone 8+ with my 100H without any problems. I’d like to dedicate a cheap tablet to it, in order to have a bigger screen and touch controls, and mount it to my mic stand. Does the Amazon Kindle Fire Tablet work with the gateway app? I know iOS and Android are compatible. What about Fire OS, or whatever it is that Amazon runs? Thanks for answers. 

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.

Hello, just purchased a Code 50 and so far I'm very happy with the amp but there are still a few things unclear with the Presets and Gateway. I have connection with my laptop or via android, that all works fine. I've downloaded a few presets from the website and want to use them on the amp. 

- The standard 100 presets are  there when I connect to the amp. If I want to add new presets do I have to override one of the standard presets? I thought 200 was the limit?
- And another thing,  if for example I upload a new preset to the amp the name of the preset doesn't show in the display. 

I tried the manual or Youtube tutorials but none are very clear on this subject. 

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

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.
