See post below: https://community.hornbyhobbies.com/topic/35259-app-crashes-too-many-dongle-locos Issue reported to HM CC and video of problem was requested. Workaround: None known at current time. Hello Gilbo2, Could you let us know how many locomotives you currently have registered in the app and if are they all set to active? I am asking because there was a known issue in earlier versions (up to version 1.1) where registering more than 55 locomotives, especially with images, would cause the app to crash and corrupt the database if all locos were active. Thankfully, this bug was addressed and fixed with the release of version 1.3. I assume you updated the HM/DCC app and are already running version 1.3. I want to mention that I don't use a dongle; my setup relies solely on Bluetooth. For users who encountered the bug in older versions, a temporary solution was to deactivate some of the locomotives in the engine shed that were not in use. This way, you could keep a few locomotives activated at any given time for use. There's a screenshot attached that illustrates this: it shows one locomotive activated while the others are deactivated on my iPad. You can toggle the active or deactivate status directly on the locomotive's settings page, accessible from the main loco screen. This is where you can also switch between running modes, such as Bluetooth or DCC, for your selected locomotive. Please update the group if that works, but my thoughts are this could be an issue only with the code controlling the dongle. . 1 Link to comment Share on other sites More sharing options...
gilbo2 Posted March 1 Share Posted March 1 Hello @The Last Ninja, thank you for your most relevant reply and information.

96RAF Posted March 1 Author Share Posted March 1 Current advice is that it is likely an app memory problem, so please place an arbitrary limit of 30 loco images for now to avoid crashes until it is fully investigated and a fix is found. 1 Link to comment Share on other sites More sharing options...

Thank you, the other recommendations I received was to: Ensuring full charge of the ipad. Ensuring all other apps are closed other than HM | DCC. Ensuring Low Power Mode is not ON. Ensuring you have free space on the iPad. Unfortunately in my case "the horse has bolted" so hoping a fix can be found without needing to delete and start all over Link to comment Share on other sites More sharing options...
Brew Man Posted March 1 Share Posted March 1 Can you not delete back to 30 as per Rob's advice? Link to comment Share on other sites More sharing options...
96RAF Posted March 1 Author Share Posted March 1 As you can access some screens go back and make inactive as many as you can to regain control. If that doesn't work dump loco images to free memory. 1 Link to comment Share on other sites More sharing options...
The Last Ninja Posted March 2 Share Posted March 2 Hi Gilbo2, Following a conference call with Hornby yesterday, they confirmed to me that, as 96RAF stated, it indeed involves a memory issue created by a bug in the app. The temporary workaround for you is to delete some loco images in the loco profile screens. The bug originates from an arbitrary limit on the amount of image memory allocated, mistakenly imposed by the third-party developer in version 1.3. This issue will be addressed in the next update they are planning. The intention was to restrict the app to just 20 locos when using Bluetooth to prevent crashes when over 55 locos are registered and all are active. I would also recommend closing the app regularly and reopening it to clear the memory jam when changing locos or making one active or deactivated. Another workaround solution, if you have a photo editor like Lightroom or Photoshop, is to load your images into a photo editor and save the images out at a much smaller file size. By halving the image file size of the locos in the app, you will double the images you can use until the update is released. I have attached a screen grab in Lightroom of where you do this when saving/exporting the file. Try to save the image at a maximum file size 1,000 or 2,000 K. 1 Link to comment Share on other sites More sharing options...
gilbo2 Posted March 2 Share Posted March 2 Thank you @The Last Ninja, following discussions yesterday I'd managed to find a way in to delete images until the crashes stopped. I've taken your suggestion regarding smaller images and that's worked, even significantly more than the arbitrary 30 limit. Images are not quite to the same standard, but they will do for now 1 Link to comment Share on other sites More sharing options...
Matt-710603 Posted March 4 Share Posted March 4 Hi all. Has anybody encountered being unable to download sound profiles? All worked well last week and today the import running functions and sound profile options are not selectable… firmware etc all updated ok. App removed and reinstalled also (iPad). Thanks in advance Matt Link to comment Share on other sites More sharing options...
96RAF Posted March 4 Author Share Posted March 4 Already covered in great detail several times in both TT120 and HM7K sections. Use the profile page until its fixed. There is almost never any need to delete the app as you lose everything and have to start again. Power cycling is all that is necessary. Link to comment Share on other sites More sharing options...

Charles-253087 Posted March 26 Share Posted March 26 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. 1 Link to comment Share on other sites More sharing options...

I had to reload all my locos with the images reduced to about 50k. Link to comment Share on other sites More sharing options...
Sly401 Posted April 4 Share Posted April 4 Not seen this mentioned anywhere- I set the function button for the brake to toggle (the switch option) a week ago I had a problem and removed my loco from the track - this occurred when in shunting mode and the brake toggled ( I think) Next day I tried the loco and it was running very poorly, despite resetting all cv's then uninstalling the profile and even resetting the decoder the poor running (well it wouldn't run to all intents). Today I had another go - the brake function had been reset according to the app when I pressed the brake function key (not driving controls) the loco moved so I reset it to toggle and applied the brake function and the loco moved smoothly but slowly so putting 2and2 together I realised that the brake was on for the past week, and the toggle was effectively the other way round when the brake function is lit the brake is OFF and when it is not illuminated it is ON ( I was thinking I had a burned out motor). so as it was running albeit slowly I tried putting the shunting switch on and yep it now ran at a much better speed Took shunting mode OFF and back to slow speed So it appears that if you power off with a function engaged that setting then becomes the default and is working inversely Then there is the secondary issue that this was not cleared by a reset , uninstall and re-install of profile or even a hard reset using the password.

Steve-738643 Posted April 26 Share Posted April 26 Not sure if it's a bug or problem with the decoder but after working fine for 2 weeks my loco now moves a few inches then stops, all sound stop. After a few seconds it will move off again without any prompting or finger pushing but the sound and lights do not come back on. I've cleaned everything and ran the layout on DC and everything works fine. The loco works fine using the Hornby app. I am using a NCE power cab and I've found the same problem using a Bachmann EZ command. The decoder is fitted to A Hornby class 31, the decoder id HM7000_4885 Thanks for any help. Steve. Link to comment Share on other sites More sharing options...
SteveM6 Posted April 26 Share Posted April 26 Assuming you have updated the sound profile to the latest version? Is a Powerbanks fitted? It sounds like dirty track or pickups or possibly an overload tripping the NCE as you say it's ok on other controllers. Link to comment Share on other sites More sharing options...
Steve-738643 Posted April 26 Share Posted April 26 It hasn't got a power bank and I've cleaned everything. It even stoped on a rolling road. I thought if it was dirty track etc it would need a push to get going agin but it starts automatically. Interested to know how it could be tripping out?
