I am having problems with the new firmware on my code 25 and gateway app on an iPhone.  It used to work fine but now gateway is not connecting to the amp.

Dear Marshall team:

I use the Code 25 amplifier, with the Gateway app and the Code series footswitch. The firmware is updated with the latest version available.

For a long time I have been noticing certain problems, mainly:

-The preset settings are changed on their own (sometimes the volume, other times the gain...) They are usually changed to the settings on the control knobs. I load the preset again, and after a while some of the settings are changed again.

-Another problem is that after using a preset for a while, when changing to another it does not change (it stays blocked). It does not respond either by using the pedal or by changing the preset from the app I have to turn off the amp. At first I thought it would be a Bluetooth problem, since I was using the Gateway application, with an iPhone. But now I'm using it with an Android phone and I continue to have the same problems.

Waiting for your comments, receive a cordial greeting.

Eduardo,

Hi,

I've just received my Code 25 amp today. It sounds good but I cannot pair it with my iPhone

It appears as "Headphones" in the bluetooth settings. When tapping on it, my iPhone says "Pairing failed "Headphones" is not supported". 

I've tried with 4 different iPhones (all up-to-date) and got 4 times the same trouble

I've successfully updated the firmware of my amp (MCU 1.47 / BT: V3.2) but it did not fix the issue.

Can someone help ??

Thanks !

After selecting a Preset, and after playing a song when I go back to the Gateway app I see a message saying, "Amp Disconnected, Connection with your CODE amp has been lost. Please check your amp and try to connect again." When I select "OK" it reconnects then I can select a preset. This seems like a new"bug" since the Gateway app has been updated to the current version. My iPhone is on a stand close to my CODE 50 the entire time. (about 1 or 2 feet at most).

Please advise. Thanks!

iPhone 13 Pro, iOS 16.4.1

Firmware: 01 Sep 2022 - v1.47

CODE 50

I have installed the IOS app, and I have two Marshall speakers: the Acton II, and the Stanmore II.

The Stanmore had no issues, I suspect because it does not require a firmware update (yet).  The Acton II on the other hand, will not connect without a firmware update.  Taking that route, it leads to an indefinitel hang.  It starts and never moves past the 20% mark, and it stays that way indefinitely.

I've tried power-cycling the speaker.

I've tried factory-resetting it too.

I've also tried installing the app on my Mac (rather than the iPhone), with exactly the same results.

Nothing.

Anyone else come across this?

Updates from a Marshall support call to which I have responded:

Hello,

Thanks for contacting the Marshall Support Team. 

Let's try a few steps to see if we can resolve this issue together.  

First: it is important to note that the Marshall Bluetooth app is NOT needed to pair the speaker to your phone. Please keep the app closed until you get to the very last section of the instructions below. 

(1) Perform a factory reset of the speaker:
- Press and HOLD the Source and Play/Pause button for 7-10 seconds​...DONE​
- The SOURCE LED's will all flash quickly to confirm the reset was successful...DONE
- Remove the II Bluetooth from your audio device’s Bluetooth list before pairing again...DONE

(2) Connect the speaker to your phone via Bluetooth:
- make sure the Bluetooth menu on your phone (device) is CLOSED...DONE
- set the source to Bluetooth...DONE
- push and hold in the source button until the Bluetooth LED Light is flashing...DONE
- open the Bluetooth menu on your phone (or device), find & select the speaker...DONE

(3) Attempt to update the speaker again, complete these steps in this order:
- update the app to the latest version...DONE[UpToDate]
- make sure your phone and device are next to each other...DONE, and
- make sure that the speaker is powered on and connected to your phone via Bluetooth...DONE
- attempt to complete the update again...FAILED

Let us know if this helps.

I am using Macbook Air M1 and iPad pro M1 with Acton 2

What should I do because I can't update the firmware because it hasn't been downloaded more than 50% even after an hour?

Quelqu'un pourrait il m'aider s'il vous plaît je n'arrive pas à connecter mon ampli code 50 sur l'application Marshall gateway il me met ce message: CONNECTION REJECTED You may only control amps you are already connected to for audio output.

Je précise je suis sur iPhone 13 dernière version d'iOS.  Le téléphone lui se connecte sans problème à l'ampli je peux joué de la musique mais c'est tout 

j'ai au préalablement supprimer et réinstallé l'application gateway, reset l'ampli, mis à jour le firmware de l'ampli, déconnecté l'ampli du téléphone et oublier l'appareil Bluetooth, essayer sur un autre iPhone (7)... bref je suis perdu du coup je ne peut en aucun cas faire mes préset depuis mon téléphone et c'est frustrant enfin bref si quelqu'un a une solution miracle je suis preneur et merci d'avance 👌💪

I just bought the code 25, and only had it for a few days.  It was great on my iPad for effects via bluetooth, although after  I updated the firware it wont connect to thre app on my ipad anymore, it plays songs from my itunes app but the Gateway app says Im already connected and nothing works to adjust the affects. Im really bummed about this, any word on why this is happening and how to fix it?. 

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?

i have just bought my code25( oct2020) and see that we need to update firmware when needed , how do i know or find out which version my amp has ? i see that my gateway app shows me i have 1.5 so why doesnt that when connected to amp tell me which version of firmware the amp is runningi  surely updates should be like on iphone you get a reminder?

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

Can I use my iPad too update firmware for code 25 .

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. 

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?

Hi,

I have a problem with my new Stockwell II. It plays the Bluetooth connection sound while playing music with my iPad Air, which is only 10 centimeters away.

The intervall between this sounds is not constant, between 30s and 15 minutes. But quite annoying. Music playing is not interrupted.

Any ideas what to do? Maybe a firmware update? (But my windows 8.1 pc doesn't recognize the speaker.)

Thanks!!!

I just got this head recently and installed the latest firmware update the other night (6/20/2019).   When I try to connect my IPad through the My Marshall app it seems to be a hit or miss proposition but more miss than hit.   In my settings on the IPad it shows me as connected, and the blue light on the head goes from flashing to solid.  On the app, it shows the head detected but when I press on that I get a "Connection Rejected"  (You may only control amps you are already connected to for audio output) and there's no control over the head from the app.   Now several other times it syncs right up.  I'm at a loss though.  Am I doing something wrong maybe in the sequence (operator error) or is there an issue somewhere else.  The manual doesn't really reference Bluetooth that well.  I'm not bluetooth savy becuase I rarely use it except for my phone in the car and connection there is automatic after I initially set it up.

So is it me?  Is it the gateway software?  Is it the head??   Help please?
