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

Please read this post in the spirit in which it is posted.

I monitor these forums regularly as I have five Marshall CODE amps. and I guess I like to see what's going on and stay up-to-date.  And I suppose I enjoy sharing my knowledge and helping others where I can.  I must also note that I've not had any of the issues described on these forums with any of my CODE amps.  And I must also note that I think they're the best modelling amps. around i.e. they're Marshalls and enough said.

But what concerns me (and hence this post) is this: there really does seem to be a lack of interest on the part of Marshall Amplification when it comes to the CODE range (at least here on the forums i.e. if emailing Technical Support yields different results then I do apologise) (and given the fact that I've had no issues at all with any of my CODE amps., as noted above, I've never had to contact Technical Support so I would not know).  It's almost as if Marshall regret the day they got into this modelling business (and if that's not the case: sorry but that's my personal impression at the moment after, what, around eighteen months or so of monitoring these forums???).  I mean to say: there are so many posts around here (dating back) asking for feedback re: apparent bluetooth issues, projected dates for new firmware updates, etc. etc. etc.  And no answers.  There's even been one or two posts asking if Marshall is going to continue with the CODE range or if it's something they want to get away from.  No answer.  I think you get the picture.

The above being said: I do understand how frustrating it must be to be asked the same old questions over and over and over again ESPECIALLY when a forum member couldn't even be bothered to search the forums for an answer before posting and asking a question or before reading the manual.  Hell: if I had a few USD or GBP or EUR for every time I've answered a question on here re: standalone software to control these amps. well, then, I'd probably buy some more CODE amps.!!!  LOL!!!  Point is and all jokes aside: I do get it.  But it's no excuse for a lack of response on some very key issues (like those mentioned above).  And what's more: for some they're not asking for favors i.e. they're quite willing to help themselves but need a little bit of input (the Master Volume issue comes to mind here) and they just don't get that input.  And (back to the firmware issue): some are even prepared to roll back their firmware to a previous version as (apparently)  some issues were not issues in previous versions i.e. they're not even insisting that a new, immediate, firmware update with fixes is made available.  Fairer than that I don't think they could be.  But: no response (or, in some cases, a very non-committal response anyway).

In closing: I don't know if I'm correct in my assumption that Marshall isn't too interested in this CODE range of amps.  I also don't know if, maybe, this (perceived on my part anyway) lack of interest is because this particular market is quite tough nowadays (what with other modelling amps. and a plethora of plugins and the rest of the junk out there) and maybe the core business (the more expensive and professional products) is being conentrated on and these CODE amps. are just an irritation.  But you need to know this (as I have noted already): they are STILL Marshall amplifiers.  And there is nothing on the market (whether it be another modelling amp. or a plugin) that sounds like these amps. (or, at very least, comes as close to emulating the more expensive and professional Marshall valve amps.).  So they are actually something to be proud of Marshall.  Just bear this in mind going forward.

As I said: please read in the spirit in which this is being posted.

No response is necessary either.  But please do take cognisance of what I've posted above going forward.

Regards,

Dale.

Hey Marshall,

I visited the dealer recently and tried another CODE 25 amp in the shop with the same latest FW version.
The same bluetooth behavior was observed (as described in many threads here, for example this ).
If you insist that it's a HW problem - please make an official statement that CODE 25 amps with serial numbers XX-XX have faulty Bluetooth Modules and you would like to recall/replace it. I think you can easily check your production and make a quality check on this case.

I think there are only few ways forward:

-  a FW update with a fix, promised a long time ago. Is it really so hard to rollback a piece of code, revert some changes from the latest FW update? 

- official recall, so that we just return it and get a 100% working unit instead.

- make the firmware code open source, so that we could fix it ourselves and make further improvements.

Regards,
Ilya

Hi, I have a Marshall Code 50, purchased in the US in 2016. I moved to Germany by the Dec. of 2017 and for whatever reason it stopped working. The PSU was replaced and the latest firmware at that time installed (repair done at Musik Meyer).

It worked fine until today, when the bluetooth is not connecting anymore. Any of my devices with bluetooth can detect the amp. I already tried installing the latest firmware, reseting to factory settings, "last resort" process on troubleshooting guide.

How can I get this issue fixed?

Hi, I already asked 03 Apr 2018. 

(https://my.marshall.com/forum/question/1308/there-is-a-problem-with-the-bluetooth-connection-since-the-firmware-update.?filterType=recent&myActivity=True)

But there is still no news of the firmware that fixes the problem. How long do you have to wait?
If you plan to take a long time to upgrade your firmware, be sure to downgrade to a version older than V1.41 that has no Bluetooth issues. I am very angry about your unreasonable follow-up care.
Hope to have a quick solution.

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. 

Bluetooth issues with the latest firmware and Code amps are well known (v1.41).  These issues did not exist with the previous firmware.  I'm sure many would simply like to revert, but Marshall has been telling us they have been working on fixing this since October of last year.  Alluding to new firmware coming for quite some time now... 

My questions are simple.  Can you give any sort of an actual ETA for the next firmware revision for the Code amps (Code 25 in my case)?  If no firmware revision is soon forthcoming, will you offer us the option to revert to the previous firmware until an actual fix/update is ready?

Not asking if you are still working on things here, or if you may consider a revert option.  Asking if there is anything solid to give us here in hopes the issues firmware v1.41 has caused will soon be resolved (or not if that should be the case). It's been long enough I think, please just let us know.  

Like apparently everyone else, my Code 25 "forgets" to turn on Bluetooth, and I have to restart the pairing process all over again, everytime I want to play.  I have to delete the pairing from my phone, turn on bluetooth pairing on the amp,  and rediscover the amp.  EVERY FREAKING TIME.  Where's that update to the firmware?

Hola,

Compre un code 100h recientemente y realice la conexión vía Bluetooth, pero genera un ruido como un pitido muy molesto, ya realice la actualización del firmware pero continúa, realice un cambio de ubicación para descartar interferencias y revise polaridad de las tomacorrientes, pero aún se mantiene el pitido, alguien me puede ayudar ¿..?

Gracias

I guess with Marshall being a small company without much expertise in building amps, this should be expected.  Maybe once they've been around a while and get the hang of building amps then they'll be able to release products that work as advertised and that they are also able to maintain and provide support for.

Hang in there Marshall, you'll be a good amp company someday!

After I power off the CODE 25 and power it on again, it doesn't start Bluetooth connection automatically (there's no blue light) and I have to press 'rev+power' and perform pairing every time. It looks like the amp just doesn't store bluetooth connection configuration?

So for every guitar session I have to start bluetooth manually and re-pair the device which is not convenient.

Could you please give a possibility to downgrade the firmware? I've read that bluetooth auto-connection was working fine on previous version.

Regards,

ilya

Does anybody know when Code firmware update is expected to be released?

Current version causes serious issues with Bluetooth reconnecion after the amp is swiched off.  Also Master Volume does not work evenly and my CODE 25 is definitely too loud for practising at home.

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.

I'm using the USB connection from a PC to the Code 25, and found that the ouput sound on the headphones is only mono-left mixed.  I get sound in both speakers on my headset, but when I test left/right channels, it's obvious that the sound is only coming from left channel.

This isn't an issue when I'm playing music through the Bluetooth connection, and both left/right channels come through ok.

Is there a firmware fix so that when sound is channeled through USB to the headphone 3.5mm jack, it'd be stereo instead of mono-mixed?

Hi, I am using CODE25.

I updated the firmware to V1.41 yesterday, but since the update, Bluetooth is no longer automatically connected.

There is no problem right after pairing Bluetooth according to the way suggested in troubleshooting.
However, after rebooting CODE25 not recognize the device again on the iPhone's Bluetooth settings.
So to use the Gateway app, I have to pair it with REV and Power each time
These problems have been seen since the firmware update and before that there was no problem at all.

I hope to know if there is a way to fix the Bluetooth connection problem or roll back to older firmware.

Thanks

I phone 6 user here, latest software installed. Latest firmware installed in the CODE 50 as well. I can connect the amp and my phone via Bluetooth, but the Gateway app doesn’t even acknowledge my code to connect with it. I have tried everything I have seen in these forums from un-installing to re-installing to restarting, turning off and on. I really like this amp but this is pretty frustrating, it worked when I first got it but for some reason not anymore. Any fixes for this? 

No automatic bluetooth connection after firmware update.

Please solve this problem.

Or support firmware rollback!

Hello, there. First of all sorry for my bad english.

I got two CODE 25, and it cannot be automatically paired with my phone again if it was rebooted.

When it is turned on, the blue light does just keep off and never get reconnection process.

Both of these got this issue after firmware update, and factory reset and troble shooting guide does not help anything.

I tried every ways so many times but it was useless.

There are many users suffering from this issue just like me... it is really annoying even this amp is really good.

Please leave an advice. thank you.
