HM7000 sound decoder (Firmware updated by HM | DC App in error)

[Andrew Yates1707820370]

Hi

During the setup of my new HM7000 sound decoder, the app correctly meshed with the decoder and prompted me to update the firmware. Having done this, the decoder now responds as HM6020_5051 and will not connect in the bluetooth mesh mode. I have tried a factory reset on CV8, but nothing works.

Can anyone help please?

Are you Apple or Android?

Have you used the HM DC app by mistake? The prefix on your link code,HM6020, suggests that you may have used the wrong app.

Andrew, it sounds as if you have done exactly the same as new member Roy and used the HM6000 DC APP and not the HM7000 DCC APP. Note that at the time of writing, the HM7000 DCC APP for Android has not been released yet, only Apple IOS is downloadable.

See Roy's thread below for details of what you need to do. Link isn't clickable so copy and paste the URL text into your browser.

Many thanks. I subsequently found the other posts. Obviously I'm not the first and wont be the last to do this.

The decoder does appear to work with DCC systems, so can be installed and used, with the default sounds, although it would help to know how to switch to the diesel sounds.

I need to borrow an Apple device to see what that does.

Andrew, the development team and the test team have been talking this issue through only this afternoon.@RAF96 will undoubtedly have a definitive response in due course but you may have to return the decoder to Hornby customer services to reprogram and unlink it from the HMDC app.

Thank you Steve.

If that's the case then I'd better get it done soon as I can see Hornby being overwhelmed with returns, as soon as these decoders hit the mass market.

There is no switch from one sound to another. The process is to load a completely new sound profile onto the decoder over-writing the factory test profile.

With regard to the wrong firmware load, the HM6K app will be updated to deploy a filter that precludes ever being able to detect a HM7K device much less be able to load the wrong firmware to it.

Can I please ask folk NOT to use the wrong app in the meantime.

The advice on the other post should be followed telling the HM Customer Care folk your tale of woe. There is little to no chance of you being able to recover the device yourself, so a replacement is the only way forward.

Unfortunately priority is being placed on getting the Android app to market and sorting out if there is a profile loading problem or not.

Can I suggest adding “Firmware updated by HM | DC App in error” to the title to distinguish it from other threads with similar titles.

Funny I loaded the wrong app (not my fault QR Code pointed to wrong app initially), supposedly reprogrammed it but nothing happened. The decoder still works as a sound decoder, so could it be that something else is going wrong?

Thank you @RAF96.

I have sent an Email to customer services, to get my decoder sorted out/replaced.

I really applaud Hornby for the technological advance and look forward to using bluetooth control.
