Hi Marshall 

I just bought a code 25, downloaded the app and tried to pair my amp to my phone which is a One Plus 3t.

However it doesn't pair like my Bose speaker, it only associates but nothing more, then in the app I can't manage to connect to the amp. Is my phone the problem? 

I bought a Code 25 for myself and my son. An older version of the app worked well but this latest udate is a complete joke ! I updated the firmware as well as the app a week ago and what a disaster!

I have spent hours and wasted energy trying to get the Gateway app and the CODE 25 to pair. I have followed every single piece of advice and  NOTHING works

For a company that makes quality products this has turned into a fricken disaster! There are so many complaints about the CODE 25 and 50 not pairing and it seesm that Marshall are doing diddly squat about sorting it out?? I am VERY pissed by the wasted time on this that I feel like throwing my CODE amp out the door into oncoming traffic!

Come on TEAM MARSHELL sort this problem out NOW... you are losing current customers and will lose future ones! 

PLEASE get back to us ASAP... it's becoming embarrasing for you!

I ask the same Question in some other Forum

And there is Help.

My Rig:

Amp Firmware 1.3

Amp DSP 1.1

Amp Blootooth 3.1

Gateway Version 1.4.1

iPhone 5s iOS 10.2.1

Here is the Answer

The first time I connected to my new Code 50 via Bluetooth on my iPad and iPhone there were no issues (2 weeks ago). Went to connect today (2/17/17) and could not with either device. 

1. Went to settings and "forgot device".

2. Shutoff amp and devices, restarted amp and devices.

3. Back to settings, Bluetooth, and paired iPhone to amp. Showed as connected.

4. Opened Gateway changed home screen to amp and tapped to sync. NOTHING!

5. Opened Menu, Code, no amp detected, tapped scan for amps, NOTHING!

Definitely a problem with your Gateway App. Please correct and email me at Olhoss.jarvis@gmail.com when issue is corrected.

if you can't correct problem please forward me the shipping costs so I can return it. The app was the deciding factor for going with the Code 50.

I was able to connect only once. What am I doing wrong? Help!

When will there be a firmwear upgrade to correct the bluetooth connection problems ? I have followed all the instructions on the forum and still only occasionaly manage to get a connection before it disconnects or freezes at rehearsals which is very frustrating to say the least.

Come on Marshall this is becoming a big issue 

I just bought this amp yesterday after flirting with a Blackstar HT20 and realising I wanted a Marshall again. Well, starting to wish I hadn't bothered.

Like so many others, I can get my phone (Samsung Galaxy S5) to connect to the bluetooth and actually play music through the amp. BUt Gateway will not find the amp within the menu. I've tried all the uninstalling Gateway, reinstalling, updating the amp's firmware - even tried using my daughter's Samsung S4-mini which again, connected to the audio but will NOT FIND THE AMP!

I have a Samsung Galaxy Tab 4 which is a good wee tablet but apparently isn't compatible with Gateway.

Seriously. So I have 3 different devices and not one of them can connect to my new amp.  Clearly this is a fault with the amp itself since the same thing happens with two different phones.

Please don't tell me to go through that long list of uninstalling, reinstalling, removing the bluetooth device and reconnecting etc etc. I've been doing all that since I got the damn amp yesterday afternoon. 24 hours later and none of it has worked.

Is it at all possible this is going to be addressed SOON in either a Firmware or Gateway update? Clearly, if the amp is faulty I will need to return it soon to get my money back but, honestly, I'm loving the sounds I'm geting with the presets, I just want to edit them rather than all the hassle of returning the amp to the shop!

I saw a review on the Google Play Store for the Gateway app from a guy in June 2016 - that's 7 months ago - and he was having the exact same issue. So if it's not been addressed in all that time and Marshall are still sending out these faulty amps, what hope for a fix? Please tell me there is one!

Hello !

Like many of lucky owners of Marshall Code 50, I also have problem to pair Gateway app with Code. My phone (Ulefone Power with Android Mashmallow 6) recognize amp thru bluetooth and even play MP3 music, but can't work with Gateway. I wonder why ? I tried to rebooth code and phone several times, also install and uninstall app few times, but nothing helps. I upgraded firmware on my Code 50, still nothing. Can i expect fixed new version of gateway soon, and will it be tested on more smartphone brands ?

So I just got my CODE50 two days ago and yesterday was the first day I had to play around on it, and that being at a live rehearsal of all places.  I didn't get to do much tweaking, but I noticed a problem with the EQ. If you have all buttons deactivated then the Bass Mid and Treble knobs do absolutely nothing, NOTHING...  I tried using the Natural preamp thinking that maybe the EQ knobs are strictly digital and an amp or preamp needed to be activated to enable the EQ to function.  When the Natural preamp was selected, however, the overall volume (master knob all the way up and the volume knob at 12 o'clock) was so low hardly anything could be heard.  Am I missing a menu option to set the volume or something?

Also, I've saw a lot of people having trouble getting the Marshall Gateway app to connect to their CODE amps, myself being one of these people unfortunately, but I haven't saw anyone come up with a definitive solution other than 1. Updating the Firmware 2. Turn the amp and phone off then restart both of them and try again. 3. Delete the amps Bluetooth profile from your phone and repeat step 2. 4. Call Marshall support.  I can get my Samsung Note 5 itself to connect to the amp (getting a weird message on my phone that says verify such and such number is the correct PIN for the Marshall amp but not having any further prompts on my phone or on the amp after tapping OK, but still connecting regardsless), but when I bring up the Marshall Gateway app and go into the menu to connect to the amp I can hit the scan button all day and it will NEVER find my CODE50.  What the huh?!!!  With all the other people I've saw on this forum having the same problem with the Bluetooth connectivity, you would think there would be a end-all-fix-all solution to such a massive problem. Has anyone heard anything or should I send this amp back for a refund while I still can?

Does anyone know if you can connect Bluetooth headphones before I go buy a pair 

Hello, I ve trouble with pairing my phone - lenovo s850 with Code 25 via bluetooth. I tried it many times, but my phone just cant find amp (bluetooth is on). I also tried another phones and devices with bluetooth but neither it could not find amp. Could it be broken amp or am I just doing something wrong? Thanks.

Hi there Marshall team,

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.

Just got my Marshall CODE 25, and the iPhone 6 will not find the amp on the gateway app or on the regular bluetooth settings. Any reason why?

Hi I have purchased a new CODE 50.  I have the latest firmware update but I'm finding the bluetooth is not consistent.  I have it running on the gateway app and then if I move the phone more the 3 feet from the amp the connection is lost.  The same happens if I play spotify through it the range is about the same.  Can this be imporved or do I have a duff model.  My phone is an iphone 5.

So I just got my Code 25 amp and my guitar will show up in a couple days.

Even though my guitar isn't here yet I thought I would have a little bit of fun with it tonight.  One of the features that I really liked about this amp is being able to play music like from your phone through the amp either via Bluetooth or hardwired mini jack.   I did this tonight and to my surprise it sounded horrible! I tweaked the settings on the amp and of course it made no difference because those settings would only affect the guitar input.   I played the music through the music app on my phone then also through the Marshall Gateway app and got the same results. I thought maybe it was because I was doing it via Bluetooth?   But then I hardwired into the amp and it was the exact same issue. I guess there are other ways to listen to music while playing the guitar along with it but I just thought it was a pretty neat feature to have both sound sources coming out of the same speaker but there's no way that's going to happen.   Unless I'm  doing something wrong?

Absolutely can not get the Marshall Gateway app to work with my Marshall Code 50. I have found the device (amp) on both my Galaxy S7 Edge and IPad Bluetooth settings. I have been able to pair them both to the amp. I get a prompt to use the code to pair the device. I hit ok.  When running the app it says not connected even though I am. The amp Bluetooth light is solid though the app says not connected. None of the app parameters effect the signal. Am I missing something simple here? Ive registered the amp and loaded new firmware update. 

Hey,

i cant find my Marshall code 50 on my bluetooth list. I tried to connect it to my phone and tablet. I downloaded the latest firmware update but it didnt help. My phone is Honor 7 and tablet samsung galaxy tab A. I bougt my amp about month ago, bluetooth havent work at all. What i can do??

Hi. There is no way to connect  throught bluetooth my Ipad2  with Gateway app Code25?  I've read the issue but don't wanna to buy another Ipad only for this problem. Thanks

So...just got my new code 25 the other day and bluetooth hooked up great....played a couple of days and no problems....Tonight..cant get it to hook up.  Any ideas?...Can I ultimatley just hook up USB to my computer and adjust fromt there?

I purchased a Marshall Code 25 Watt amp today, and I am trying to connect it to my phone (Samsung s6 Edge+) via bluetooth, however, my phone will not discover it when scanning for available bluetooth devices. I have reset my phone and cycled the amp, and the problem persists. Are there any known issues with these devices or any workaround that I should look into?
