BritInVanCA Posted February 24 Share Posted February 24 Is there a known problem with a significant lag in the app updating the connectivity status of a decoder. As you can see from the picture my loco is not on the track and doesn’t have a stay alive. It took about 4 minutes to change status. This is a bit of a challenge when the loco stops on the track but shows it’s still connected Doesn’t help troubleshooting Link to comment Share on other sites More sharing options...
LTSR_NSE Posted February 25 Share Posted February 25 I don’t believe this is a known issue… (possibly the device is struggling to run the app correctly?) • What version of iPad are you using? • What version of iOS is it running? • Have you closed all other apps? (to ensure it has maximum memory available) • Have you updated the decoder with all available firmware updates? Link to comment Share on other sites More sharing options...
BritInVanCA Posted February 25 Author Share Posted February 25 Bu@LTSR_NSE iPad 5 generation Running the latest version 16.7.5 I was running other apps so I will try that but it has a 128 gb capacity less than half used I didn’t think I needed a dedicated iPad for this app! The firmware/profiles any everything are the latest 1 Link to comment Share on other sites More sharing options...
Daedalus Posted February 25 Share Posted February 25 (edited) It's how Bluetooth Mesh works, there is no permanent handshake. It uses message flooding. Edited February 25 by Daedalus Link to comment Share on other sites More sharing options...
LTSR_NSE Posted February 25 Share Posted February 25 (edited) @BritInVanCA be aware there are two types of ‘memory’ in an iPad… • RAM (usually referred to as memory) - the faster kind that running apps require/use for peak performance. Latest iPads have between 4-8GB of this, older models have less. • Solid State (usually referred to as storage) - the slower kind that simply stores/holds all files, apps, data etc until they are called into use. This is what your 128GB figure refers to. An app that requires a large amount of fast memory for sending/receiving lots of rapid communications (as Daedalus explained) will be hampered/restricted/ slowed down - if other apps are running & using up some of the available fast memory.

BritInVanCA Posted February 25 Author Share Posted February 25 (edited) @LTSR_NSE yeah I know how the different types work. I used to be in the industry. Didn’t realize HM:DCC was that RAM intensive. Good information. Thanks To date myself my ZX81 came with 1K and I upgraded to 16K. That seemed like luxury!

LTSR_NSE Posted February 25 Share Posted February 25 Fair enough - hope your next attempt is more successful. 🤞 (apologies for making you suck on those eggs!) 😉 1 Link to comment Share on other sites More sharing options...
LTSR_NSE Posted February 25 Share Posted February 25 To date myself - I grew up playing with my Dad’s BBC Master & Z88 portable - using a qwerty keyboard is more instinctive than a pen! 😂 Link to comment Share on other sites More sharing options...
BritInVanCA Posted February 25 Author Share Posted February 25 @LTSR_NSE you’re going to get me in trouble for going off topic. After the Sinclair Spectrum I graduated to the BBC (Acorn) model B. Wonderful computer. My first experience was an Apple II that my friends dad had. Hand coding games or retyping from magazines. Those were the days 1 Link to comment Share on other sites More sharing options...
BritInVanCA Posted February 28 Author Share Posted February 28 OK I found some time to do a controlled test. I did a restart of the iPad and then just opened the HM:DCC app. It takes about 10 seconds to recognize a loco that has been put on the track and 1 minute (I know I exaggerated the lag in my original post) to recognize a loco that has been removed/lost connectivity. Not the end of the world I know (I won't try to classify this as a fault!) but it does make it difficult to recognize intermittent losses of power. Perhaps just an observation. My dongle arrives tomorrow so I'll be having fun setting up my conventional OO DCC locos! Link to comment Share on other sites More sharing options...
