Hi,
as per my emails, I seemingly was using the “develop” branch.
After pulling the “master” branch instead, building the code and firmware and re-uploading this is now working without changes to my RocRail layout.
So it seems, that MTC4PF has a bug in “develop”.
The issue is, that I also have been testing with MTC4BT on an ESP32 board with the same loco and ID and there it works. So I’m also sure, that the RocRail configuration is correct.
You can see my initial tests with MTC4BT here: https://www.youtube.com/watch?v=9158apj1uVk
Yes, it’s in the “my” folder in the MTC4PF project folder named “controller_config.h” together with the network_config.h file. If the files weren’t in the right location, the board would not have the details to connect to my WiFi network either.
Additionally, the board tells me, it’s configured for BR103 / loco 103 and then turns around, that the controller is not configured to handle loco 103.
Output from the console:
loco id: BR103
addr: 103
Message disregarded, as this controller does not handle train 103/M
