I have a xiaomi redmi note 8 and also have a problem connecting the marshall gateway app to the amp code50.
I can only be connected as if I were listening to music, I even tried to connect it with an otg adapter, it works like that, but there are a lot of problems with braking the application? Please if it is possible to solve this problem.

 And if I tried all variants except one, and that is to uninstall every marshall application to amplify my Marshall Code 50 Firmware 1.4.4 recognize bluetooth connection from which I can control my installed Gateway 1.5.5 of course not just music to listen to But that I have complete control and whether maybe the problem is that the usb is included in my computer, whether to turn it off because I registered everything else. If anyone can answer all these questions I will be grateful.

I have an issue with tap tempo on the Code 25 with 1.45 firmware and wondered if anyone else has the same issue.  The manual says you should "press MOD and DEL selection switches together". When I do that the amp does indeed go into tap tempo mode (tap the selector switch to set tempo), but regardless of how quick I press the buttons or if I hold down one and then hit the other it always switches on the MOD module too. The other double combination switches (tuner and bluetooth) dont do this and work as expected and only switch on those functions without switching on or off any other modules.

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 (Pixel 3a, 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 have the following problem with my Marshall Stanmore (I) Bluetooth speaker:

Whenever I am wirelessly connected, the Bluetooth connection drops after 20 minutes — while playing music!

The surprising thing is that it not just happens randomly after 15 to 45 minutes — no, it happens suspiciously regularly after 20 minutes. I went and tested this with my laptop (4 times) and my phone (3 times) by writing down the start and stopping times, and the Bluetooth connection got interrupted (the music stopped) after 20 minutes each time. 7 times in a row. No exception.

• Yes, I have removed the speaker from all devices, then re-repaired them. Multiple times.

• Yes, the problem exists with all my devices that can send sound via Bluetooth (laptop, phone, desktop,). Those same devices have no problem to stream music to my Sony sound system or portable Bluetooth speakers. The problem only exists with the Stanmore.

• No, the Stanmore is not near a wifi router, a micro wave, a DECT phone or close to other Bluetooth devices. All of my other Bluetooth devices work perfectly fine. During my tests, the speaker and the Bluetooth source were about half a meter/two feet apart.

• Yes, I have had the Stanmore disconnected from power for an hour. Even a few days, actually.

• Yes, sound works perfectly fine via the wired connection (INPUT 1) and it doesn't stop after 20 minutes. 

• Yes, the "STANDBY MODE" switch on the back  is set to "STANDARD". (But surely no Bluetooth speaker would ever go into standby mode WHILE playing music anyways, right?)

• No, I am out unfortunately of warranty. The speaker looks great and hasn't been used that much. I also find that it financially doesn't make much sense to spend 130€ (max.) on a Marshall OOW repair.

• No, the Stanmore I is not compatible with the Marshall Bluetooth app, and there is no way for me to update the firmware (as far as I know).

• Yes, I can absolutely open up the speaker and post pictures of specific components, if someone has a clue about what capacitors or chips to look out for.

Additional info on the issue:
I experience no problems connecting via Bluetooth, from any device. I can start playing music — but after 20 minutes, the music will automatically stop. If I am streaming from Spotify for example, the player will just pause. The Stanmore stays powered, and the red BLUETOOTH light on the Stanmore is still on, but it appears a little dimmer than normally. I have found that pressing the SOURCE/WAKE button once usually wakes up the Bluetooth connection again, and then after a while, I can resume music by un-pausing on the laptop or phone. 

Thoughts? Ideas?
The fact that this happens after a very precise operating time, sure sounds a lot like it could be standby-related. But the Stanmore is not set to POWERSAVER mode. And even if it was, it would only enter standby mode after a certain time if it wasn't playing anything. A speaker that goes into standby mode every 20 minutes WHILE playing music ... that would be ridiculous! And yet, that is exactly what I am dealing with.
Any ideas or clues for what to try or look out for?

Hi, I just recieved my Code 50 yesterday "bought brand new" and the amp sounded great until i hooked up to my pc this morning and downloaded a featured preset not a communiy preset. I am running usb not bluetooth and its my studio setup. Now all the distortion and gain sounds like the input gain is wide open clipping the signal coming in at all volume levels, and on all distortion and od gain presets. I tried to reset the amp and did a firmware update now its litterally so bad you cant play it. This is certainly a software issue cause the effects and clean tones sound fine. This happened immediatley after i sent the preset usb from the website to the amp from the pc. Also i tried several guitars, usb cables, guitar cables and even my mac. just dont know wether i should send it back or if thiscan be fixed with a firmware patch or something , Thanks

I have followed all the Forum and Support threads, re-installed current  Amp firmware, updated the Gateway App, restared everything several times... the iPhone does not see the Amp when blue light is flashing to 'pair'. Also not visible to ipad or other devices so I'm assuming it's a problem with the CODE system itself. I haven't even got as far as connecting the Gateway App!

Looking through the forum, this is clearly not an isolated event - looks like the Amp firmware is WAY behind current Bluetooth versions.

Any suggestions please? I am still within my return for credit timeline - should I send it back to the dealer?

Hi,

I have updated the firmware and it has totally messed with my amp. Footswitch is intermittent, bluetooth is awful. Anyone had a similar issue?

Yes, I've read the many questions of the same nature on the forum, and performed all the suggested actions. None of them have been successful.  I've seen many questions similar to mine, and only a few who have been able to make it work... and of those who did, their solutions didn't work for me.

When I connect my amp to my phone's bluetooth, it will pair for audio with no problems.  I can play audio through the amp.  When I open Gateway, there is no "red button" prompting me to connect.  When I tap on the CODE tab in the menu, it says "Not connected" and when I tap on the green "Scan for apps" button, nothing happens.

It will connect to my Samsung tablet with no issues.

Here are the steps I have tried:
Factory reset on the amp.
Unpair  and forget the amp in my phone's bluetooth settings.

Uninstall the app from my phone after clearing the cache and the data.

Update the firmware on the amp (the browser window said I was up to date but I installed the latest firmware anyway.)

What else can I do?  I don't want to return the amp because it sounds great, but not having the amp controls on my phone is a deal breaker.

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?

Hi,

I have found a weird thing that may or may not be known with iOS + Bluetooth and the Code 50.

The CODE 50 when playing backing tracks / using it as a Bluetooth speaker is very quiet (So the master is wacked up and the playing guitar is extremely loud). 

and the weirdest thing (which physically makes sense but still it shouldn't do it) is that the Amp is predominatly a Left speaker when playing music through bluetooth as my phone (iPhone 6S) thinks my amp is bluetooth headphones rather than speaker (as the headphone icon pops up on the top right). 

My amp is on the latest firmware update.

Is there any fix for this? There's nothing in the gateway app for audio balencing

The new Stockwell 2 seems to come with an auto-standby mode, meaning it shuts off after between 5 min and 20 min (seems to be different from a phone versus a laptop?) even if the connection via bluetooth or jack-in is stable. Although the sound is nice for the size, the speaker is barely useful in settings where sound is not played all the time.

Team Marshall, can you please provide an option to define a custom time (let's say 2h) or completely disable the  auto-standby mode either by a Firmware update ob by integrating the Stockwell 2 into the Marshall app? Thanks.

Best
Rey

I can't get the phone app and code 100 amp to connect. bluetooth does connect but the app will not show or allow to connect thus make the app unsuable. i have redownload app manty time. reconnected phone many times. amp is up to date firmware. i have had the app working fine and connected in the past.but now no matter how many redownloads, resets and starting fresh i can longer connect with the app to control it. i have been through every setting and all combinations on connecting updatig reseting and nothing seems to work. need help please. thank you.

Got an issue with my Marshall Stanmore wifi speaker. When playing music through Wifi or Bluetooth the volume always goes down on its own. Have to turn up the volume between 5-10 times before it stops turning down the volume on its own. Wifi and Bluetooth connection are fine, it has this issue which each connected device I've tried and with all apps (spotify, Google Music, YouTube,...). Any idea on settings or stuff i can check? Maybe a firmware update something? 

Guys - 

You need to get someone to fix the Bluetooth capabilities with this product line, like, yesterday. I updated the firmware yesterday, which was extremely difficult to do in the first place, uninstalled / reinstalled the Gateway app today, and still cannot connect to the amp except via my phone's native Bluetooth options to use it as a speaker. I am running ios 13.3.1.

I've scoured your web site, I've watched your videos, I've been all over Google and Youtube, and I am nowhere. In addition, I'm legitimately concerned by other reviews that the amp is simply not going to sound as good given I've updated the firmware. Will post again if that's the case. 

I will see if I can push new presets to the amp via a hard connection to my PC, but you need to do serious damage control on this product line considering your leading selling point has proven to not work as intended, if at all. 

Marshall Code 25 Bluetooth not working !!!!

i try to update firmware to 1.44, i try with diferente phones, android/ios/tablet etc.... wont detect nothing.... bluetooth Marshall not appear!... 

Marshall apps is a fucking crazy bad... and support too.....

Need help please. I love my marshall code 25, but without bluetooth i send it back....

Hi I have a CODE 100H head/cab and a CODE 100 combo both with the latest firmware re-installed from Marshall and both have this issue, i.e. the amp very oftenn completely freezes when I save a preset.

Steps to reproduce:

- Modify any patch on the front panel

- Save

- 50% of the times the amp seems to freeze. The preset is saved but you can no longer change preset and there is no sound coming out.

The same happens if you modify a patch from the iOS app via bluetooth and then save it from there.

It's REALLY frustrating and I can't believe I didn't find anything on this forum under the "crash on save" keywords. Seeing it happens on both of my CODE units it much be a software bug, I don't think it has anything to do with my units.

Anyone else has seen this problem?

Thanks!

I have a code 50 and am trying to update firmware. I have an iPhone X with the Chrome app installed (newest version). I am logged into my Marshall and the gateway app. The gateway app shows I am connected via Bluetooth, but on the my Marshall firmware download page it says I am not connected and my browser doesn’t support download. 

It’s very frustrating, Marshall or any support appreciated.

Just bought my Code 50 tried to connect the Gateway App to either my iPhone 7 or iPad Air 2.

Did a firmware update to 1.44 , the amp is paired in Bluetooth but when in Gateway, it just says it is connecting but never does.

I have tried reinstalling the firmware, forgetting the edvice and re-pairing, removing all other BT devices etc. etc. but still it will not connect.

UPDATE: this was an iOS issue, not the amp. The latest update to iOS beta 13.1 resolved it. 

The iOS Gateway app was unable to connect to my CODE 50 even though my MacBook Pro is connected via bluetooth, so I did a factory reset and then tried to do a firmware update. The first part of the firmware update (1.44) appeared to install correctly. Next I saw a DSP update and tried to apply that update. In the middle of the DSP update, I received an error message to the effect that the update failed and I should power off & on my computer/device. I powered my Mac off & on, but the CODE 50 shows a progress indicator (about 20%) and says "DO NOT SWITCH OFF."

I tried to reinstall the firmware/DSP update, but this time the update process would not even begin. I suspect the  problem is the frozen progress indicator and whatever ongoing or frozen process is causing the "DO NOT SWITCH OFF" message.

Othe than ignoring the warning on the CODE 50 and powering it off & on, I don't see what else I can do. Is there a way to abort the ongoing or frozen process without turning the CODE off.

What should I do?
