Hi.

I have a set of Minor II Bluetooth headphones and they’ve worked great up until I switched from an Android phone to an iPhone. I like to have them connected to my phone and also my laptop at the same time whilst working. The problem is since I’ve been using the iPhone, I keep hearing the short noise as if the headphones have just connected to a device over and over again. Every minute or so, the sound dips and I hear that noise. It’s extremely annoying and I end up having to disconnect from the phone to stop it. Does anyone know how this could be fixed?

Thanks

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. 

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.

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

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,

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, 

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,

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.

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

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.

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.

Regards

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?

     I picked up a Code 50 last week so far I love it and the possibilities it offers.  Only issue I have had is when the Bluetooth is connected to my phone (Samsung Galaxy S7 Edge) if I get the phone too close to the amp I get a weird digital rattling sound coming from the amp.  I have not tried to see if same issue happens with my Android tablet though.  Has anyone one else had this problem or know the cause?
