[HM | DCC (HM7000) bug reports (app and decoder)]

On 26/03/2024 at 10:06, Charles-253087 said:

Having installed the HM7k app with Dongle on Moto play 6 (because my Galaxy Tablet is currently incompatible with the app) and got it working with a couple of locos I have experienced two app crashes. The app crashes to white screen and does not respond to a Forced Stop or Clear Cache. Only Clear Storage fixes it, but that loses all input data for 30 locos etc.

Am I the only one to have experienced such an app crashes. Using other software, one of the first things to do is to backup/save the input so far. With many 'keystrokes' required for each loco and accessory, a crash is catastrophic and off-putting.

What is the recommended method to backup all this add data? I have tried several general Google backup methods. All to no avail. Shouldn't there be a built-in save data/backup facility? I would like to keep a copy of the data 'off site' as a backup.

I had this happen, and only fixed it by deleting the app and reinstalling it.

I had to reload all my locos with the images reduced to about 50k.

I have used 2 apple devices at once with no problems having divided the fleet between them. It helps keep 2 children happy at the same time. I did make sure that the locos are only on one device.

How do you get two iPhones to both link to one TXS decoder?

[HM7000 Dongle - Nice piece of kit]

I have just bought another dongle to use with one of my Samsung tablets.

Problems with two on version 14, but great with one on version 12. 
Until I loaded up a large quantity of locos with pictures that is.
It crashed and now only displays a white screen on the app.

Is this a known problem, and can I correct it?

Both of those features have been discussed previously.

Where would that be?

I am struggling a bit with the new format, and am still getting used to it.

[HM7000 Dongle - Nice piece of kit]

This has features not seemingly mentioned in any literature.

You can modify the order of the locos in the top panel to your hearts content.

You can deactivate all the locos you are not running to simplify those being shown on the top panel, making moving from one loco to another much easier.
I wonder what other hidden features there are to be discovered.

This is one very well thought out item.

 

[HM7000 Dongle - Nice piece of kit]

Thanks for your suggestion 96RAF.

It works a treat. Just entered another ten locos. Quite quick when you get a rhythm going.

Tempted to get another dongle to use with my Android tablet, just for fun.

[HM7000 Dongle - Nice piece of kit]

By function, I mean the correct map.

How do you download the sound functions to each loco?

I have set up three locos, and have downloaded the sound functions on one.

All good. However I can’t do it for any more.

[Downloading the rm software.]

On my tablet I only run Windows Defender.

I disabled it and managed to download the app.

However when I re-enabled it it ‘attacked’ the download and disabled it.

Didn’t use to behave this way. Used to to allow me to override it.

All is ok now.

[Downloading the rm software.]

Thanks for your replies chaps.

i was trying t download the latest version on my new laptop.

this has Mcafee and Defender. I tried switching them off with no success.

My Linx tablet only has Defender, which I turn off completely. Success.

Is 1.74 rev 5 the latest?

[Downloading the rm software.]

I have been trying to redownload the rm app to ensure I am up to date.

I have had no luck whatever I do.

I have searched this forum and have found nothing to sort it out.

It must be downloadable, and I have done it many times before.

Any advice?

[Bachmann class V2 sound profile]

I have a sound fitted V2 and one with the HM7000 decoder with the A1 file.

The stock one sound far better than the HM7000, but both are good enough for me.

[New Profiles Feedback]

Thanks 96RAF.

[New Profiles Feedback]

I presume one has to re-download the profile to get the latest profile, but where does Hornby advise of the update and how you apply it?

I only checked because of this post.

[Reflections on HMDCC after 6 months]

All I can say is that I am bored with it now, but in a good way.

Everything works as it should and no problems to solve.

I now have to play trains, and have never been good at that.

Just needs more sound profiles to be perfect.

[Bachmann V2 sound profile]

I have one Bachmann V2 with pre fitted sound and one with the HM7000 decoder(A1 profile).

They sound nothing like each other on the chuffing.

I actually prefer the HM7000 chuffing, as the beats of the fitted decoder sound rather clickity clackity to my ears.

[HM7000 not working on A4 mallard record breaker train set]

Isn’t the decoder supplied ready for use on dcc?

It should work on your select regardless of what the app is doing.

[No motion with HM7000, just sound and lights]

I had this happen with a Schools Class locomotive yesterday.

Tried all the tricks to no avail.

Found the loco/tender connector was loose.

Didn’t think the decoder worked without a motor connection.

[Slow start up and slow down]

If the issue is about some cv settings, resetting cv8 to 8 should fix it.

[Firebox glow control.]

It seems as said above.

Unless there is a fault somewhere it seems that the Princess LED is wired across the power pickups and the A1 LED is wired across the decoder motor feed.

Only Hornby know why they changed it.

I can understand why the decoder doesn’t allow control of the LED is because, unlike my Bachmann V2, the decoder is in the tender. This means an extra wire would be needed between tender and loco.

[Firebox glow control.]

I have just received the Knight of the Thistle, and the firebox glow works differently to the Princess Royal.

Is off when stationary and comes on when the loco moves. Still none switchable.

[Auto calibration and speed curves]

I agree.

I am a tinkerer, and can do so without fear of destroying £60 of kit.

I love these things.

[Auto calibration and speed curves]

I went through the whole procedure with this loco. It seemed to run rather slow and undoing.

I see CV144 to 1 and it ran more smoothly but still slow.

Reset CV8 and it ran just fine.

I’ll leave things as supplied.

[Auto calibration and speed curves]

Had a go with auto calibration.

Sort of no difference with five locos, but weird results with my Hornby Lord Rodney. Very erratic.

I reset them all back to factory settings.

All good enough as they came.

[Complex Speed Curves]

Thanks 96RAF.

I’m glad someone understands it.
