In February, 2014 Tamás from Digitools contacted me. He liked the application and we decided to work together. Digitools is a Hungarian company developing and manufacturing electronics for model railroading.
The plans was to enhance the functionality of the app and to change the design a bit using colors of Digitools. Furthermore instead of using the PIC 32 Starter kit we made a more complicated circuit with WiFi module and XPressNet communication. So there is no need to use a WiFi router if you use DigiWifi, it creates its own WiFi network. Also with the XPressNet connector it is compatible with the most command stations already used by modelers.
Of course I needed a circuit which communicated with the TrainDcc application running on the android devices and generated the dcc signals for the booster. I used a PIC 32 Starter kit (from Microchip) and I wrote a program which generated the dcc signals based on the commands get from LAN. The router made my LAN connection to wireless and the android devices were connected to it.
