In working on OS-DBTC, I can across a potential DCC++ setup that some of you might be interested in. In consists of using the “Bluno SKUFR0267” in place of the Arduino Uno, and a JMRI-PC with the “Bluno Link - A USB Bluetooth 4.0 (BLE) Dongle”. In other words “a cheep wireless-UBS connection between the PC and DCC++. There is also an open-source iThing App that demonstrates a serial connection to the DFR0267 (that does not require the dongle). Bob
