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

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?

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 .

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?

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?

hi support

why do not you solve this problem???

my hardware:

Iphone X, iOS 12.1.4

Ipad Pro, iOS 12.1.4

Marshall Code 25, Firmware 1.4.1, date of purchase 12.03.2019

I bought the combo yesterday and it's full of bluetooth bugs - looking now at the FORUM my impression is that the support doesn't care about it.

- No automatic bluetooth connection - iPHONE - I am having always to force Iphone to "forget" the AMP and pairing it again... each time...

- MAC IOS , When I try to connect the bluetooth in my MAC, it makes the system crashes, mouse and keyboard stop working... there's no were to get the necessary code to bluetooth connection...

DO WE HAVE PLANS FOR A NEW FIRMWARE TO BE RELEASED SOON ? PLEASE

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

I see that the Bluetooth issue I am experiencing has been going on for some time now. I just bought this amp but I wouldn't have had I known how frustrtating it was going to turn out!

The whole appeal of this amp was that I could sit back with my phone or ipad and diddle with the settings peacfully. But no, you can't do that becasue first  you have to pair the amp and phone/ipad EVERYTIME you want to use the gateway app. 

Come on guys, really this is ridiculous. How many other people are complaing about this very issue. You can't sell a half baked product and not fix it. At very least allow us to roll back to the previous firmware. 

I have purchased new Code 100 (a demo from Sweetwater)  I am not able to connect the amp to my personal device.  When I press the Rev and Power buttons to connect,  the blue lights flash,  the device number shows up on the amp but either of my devices (an I Pad and an I Phone) will not recognize the Code amp.  The Code Amp does not show up in the "My Devices" so it never has the opportunity to pair or show up as connected .   My phone and Iphone recognizes other bluetooth items, ie, head phones, speakers etc. I have tried the FAQ suggestions and have tried the recommended fixes and I am still not able to connect.  

I have not done a firmware update on the Code 100.

Any assistance would be greatly appreciated.

Thank you,

Steve H.
