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.
Thank you for providing more information, the Bluetooth light should automatically come on after turning the amp back on, remembering its last paired connection, Bluetooth on the Mobile device should still be on and the blue light can take up to 2 minutes to find its pair device, have you followed the steps in our troubleshooting guide.
We understand your concerns but for our technical team to look into each issue further we need some more information i.e the device you are using and which phone software. If you would like to give us this information we can then look into it further for you.
Please be advised that it is not possible to rollback the firmware as previous issues were fixed with the latest update. Our technicians are working on a update to help fix issues that some customers are having, time is being taken to ensure that there are no further issues.
Ordered the code 25 and with most .modeling amps some presets are good most need tweaking.
Can not get samsung note 9 to connect to amp after hours of trying and scouring the net for solutions.
Appears the app is needed to really get the potential out of the amp.
No problem solved soon , amp goes back for another non Marshall that is not acheadache.
Fix it quick
