I’m about a year into modeling with JMRI DCC++ set up using Arduino Mega 2560 with Arduino motor shield. System has been working fine running single locos. Now, I am starting to run multiple locomotives simultaneously and the throttle communication begins to lag when I try to send for example a bell command or change loco speed. Soon after, I loose control of both locos and power button will go yellow if I try to turn off track power. Both Arduino and laptop USB baud set to 115200. This issue occurs when I use either laptop USB connection or WIFI connected tablet. Again, running a single locomotive and operating turnouts has been working fine. Thank you in advance to any help you may provide! Ron
It sounds like very limited bandwith between the base station and the locomotives, rather than a throttle communication issue. As you add more engines under control, the total packet of information from the base station to the track gets longer and longer.
I’m not sure but I think I may have solved the problem… still testing. So far so good. I am connected to my dedicated local router via hard wired ethernet. I was inadvertently also connected to same router with wifi from my laptop! I was showing 2 connection addresses on the WiThrottle window on my laptop. I turned off my Wifi connection to that router and have had no issues since. Still testing, but have high hopes…knock on iron rail! I’ll let you know the final result.
